Mousson Atelier Jewelry Scanning

Mousson Atelier Jewelry Scanning

3D scanning allows jewelers to significantly speed up the jewelry production process, which is important with the modern pace of life and great competition. Jewelry workshops simply cannot afford to spend time and labor resources fulfilling orders, while realizing that there will be few customers who are willing to overpay for manual labor. 3D modeling followed by cutting a wax model on a CNC machine helps save manufacturing time, which means it allows you to do more work.

A regular customer of RangeVision, Mousson jewelry studio creates jewelry in a modern and classic style.

The masters of Mousson Atelier have modern and high-tech jewelry production, therefore, at certain stages they also use the RangeVision PRO 2M 3D scanner. Its equipment includes 25 mm lenses, a turntable and a 40x40 mm calibration field for scanning small objects.

You can view interactive 3D models of jewelry from the Mermaid line made using the RangeVision PRO 2M 3D scanner.

How does the process of creating jewelry from Mousson Atelier work? We are ready to lift the veil of secrecy! In this article, we will tell you how to create 3D models of Mousson Atelier jewelry using the RangeVision PRO 2M 3D scanner.

The decoration in the photo is made of translucent green wax, so it is coated with a special matting spray before scanning. This procedure avoids the refraction of light, which can lead to distortion in the model.

In order to fix the object in the center of the turntable, the craftsmen use plasticine.

After scanning the object from one side, the jeweler turns it over so as to digitize the rest of its sections, which are not visible from above. Subsequently, these fragments will be automatically combined in the RangeVision ScanCenter program, which is bundled with any RangeVision 3D scanner and is designed for fast processing of scan results.

In order to combine groups of scans, one of three stitching options is used: automatic in geometry, three-point or manual. Depending on the size and shape of the jewelry, the craftsman can choose the appropriate stitching method, which is convenient.

3D resolution plays a key role in jewelry production. This parameter indicates which minimal element on the object will be distinguishable on the 3D model. RangeVision PRO 2M has a 3D resolution of up to 0.3 mm, which allows for maximum detail when digitizing miniature objects (less than 3 cm).

The image below shows the result of a 3D scan. Jewelers do all the necessary initial processing — they remove “noise" and unnecessary elements in the scanning program. The voids that usually remain in places where the model is difficult to scan are sewn up by Mousson Atelier specialists in the Leios program. It can also be used for smoothing and other refinement of the final 3D model.

The models obtained with the RangeVision PRO 3D scanner have precise detail that allows you to view the smallest elements.

How to avoid production errors and detect equipment wear in time

Algorithm for scanning large objects

Before starting the measurement, a matting spray must be applied to the object to eliminate the effect of glare from reflective surfaces. The use of self-adhesive contrast labels improves the accuracy of scanning and automatically aligns model fragments when digitizing objects with a uniform surface.

The final STL model in the ScanCenter NG software is compared with the loaded reference design model. The result of the process is a color deviation map between the two models, which can be exported to a convenient format: JPEG, PNG, BMP or PDF.

RangeVision PRO is designed with specific production conditions in mind and uses blue backlight technology to offset the effects of bright ambient lighting. The 3D scanner allows you to obtain three-dimensional images of objects of various dimensions: from coins to the body of a car.

Advantages of professional scanning in the automotive industry

The introduction of the RangeVision PRO 3D scanner into the production process saves resources needed for product quality control. Scanning and processing of data on professional equipment is possible both in isolated cases, such as reverse engineering or custom manufacturing of parts, and in serial production of products.

Prototyping, development of new models, manufacture of interchangeable components and car parts, assembly line work and car tuning — 3D technologies are used at many stages of modern automotive production. Using the example of Antolin, we showed how RangeVision PRO saved time and optimized the solution to the problem.

Quality control at the shipbuilding giant PJSC “Krasnoe Sormovo Plant”

Quality control at the shipbuilding giant PJSC “Krasnoe Sormovo Plant”

When manufacturing single cast products, it is unprofitable to make special quality control devices, and it is more efficient to resort to 3D scanning. This was done at the Nizhny Novgorod shipbuilding plant, part of the USC.

Tankers built at Krasny Sormovo have been named "Significant Ships of the Year" several times by the English Society of Ship Engineers (RINA). The share of products in the segment of river-sea vessels with a deadweight of up to 13,000 tons has been about 40% over the past 3 years. The company closely monitors the manufacturability of production processes, therefore, it is familiar with contactless quality control with optical 3D scanners firsthand.

RangeVision engineers went to the factory to scan the hub of the adjustable pitch screw. The outer diameter of the product was 800 mm, and the height was 700 mm. The foundry's technologists have set minimum allowances for its landing diameters to reduce the casting weight and reduce the cost of machining. In addition, for the first time in the practice of manufacturing such parts, some of the internal surfaces were completely finished. Therefore, the requirements for the quality of model tooling and mold assembly have increased.

It was preferable to check the actual dimensions of the experimental casting by 3D scanning, because it gives an idea of the geometry of the entire product. Without digitization, the OTC service would have to work only with individual dimensions or cross-sections.

Markers were glued to the hub to automatically align the scans, and then the RangeVision PRO 2M 3D scanner was moved around it, collecting data from all angles. One hundred individual frames formed a single 3D model in the ScanCenter NG program. A stereolithography (stl) file was exported to GOM Inspect for comparison with the original mathematical model and the generation of a cross-sectional report. Already at the end of the working day, the technologists had data on the compliance of the actual geometry and theory, shrinkage, displacement of the rods during mold assembly, etc.

Many components for marine engineering are made by casting. Typical parts: bracket legs, cleats, fairings, blades, screws, body fittings — have a complex spatial configuration, so their control by mechanical means is difficult. Previously, it was possible only after grinding in a machining shop or even on a slipway, often months after receiving products from the foundry. Therefore, 3D scanning is now recognized worldwide as the optimal intermediate method for monitoring such details.

Manufacture of individual bionic prostheses

It would seem that it is not so difficult to make an individual prosthesis and give it to the client. And how to make sure that a person uses it? The mission of the company “Motorika” is cyberactivation: to show, teach how to use, create positive emotions. Motor skills form a new attitude towards prosthetics, create an active cyborg community with support and rehabilitation, and help people regain their inner balance.

The delivery of the prosthesis is accompanied by its fitting. It is important here that nothing rubs, presses, or squeezes, and everything fits in length and volume. Getting accurate measurements is a crucial step, which is why the company has implemented 3D scanning to create future products.

Previously, the design was based on measurements that were taken by prosthetics, clients, contractors and transferred to Motor Science. The disadvantage of this method was that the measurements were inaccurate. I had to call the client again and take 10 more measurements, which was especially difficult for children, who are difficult to occupy in one place.

The process looks much faster now. The casings made to individual sizes from the cast are digitized using a 3D scanner, and the resulting 3D models are transferred to the design department and then printed.

After the introduction of 3D scanning, there is less redesign, and the scanning process itself takes several minutes, making it much faster for customers to receive accurate prosthetics.

The scanner allows you to digitize objects of almost any size, from one centimeter to several meters, with high accuracy. With this device, it is possible to transfer all curved surfaces that cannot be obtained with a standard measuring device, which is very important in prosthetics.

Creating an exact replica of a Tengrizaur vertebra

Paleontology is the foundation by which one can see how the planet developed and what absolutely unique animals lived in ancient times. Tandem with additive technologies allows you to create exact copies of fossil organisms for further study.

Scientists from St. Petersburg State University found the vertebra of an ancient dinosaur this summer.Tengrisaurus is the first Titanosaur in the history that lived on the territory of modern Russia. The four-legged and long-necked Tengrisaurus starkovi from Buryatia looked more like a South American than a typical inhabitant of the Russian hinterland.

Part of the tengrisaurus skeleton was too large and fragile for frequent use for educational purposes. In this connection, it was decided to digitize the found fossils and transfer them to the museum as an exhibit.

The scientists scanned the vertebra using a RangeVision Spectrum 3D scanner and printed it out in a reduced form, which made it possible to use an exact copy in the educational collection.

The resulting 3D model is better suited for everyday use and allows you to study fossils in detail when choosing any scale. While the fossil will keep its historical value intact in the museum.

There are more and more examples of the use of 3D scanning in science. Creating a virtual copy of the found objects simplifies their further study and allows you to leave the originals intact in complete safety.

Preservation of the Hermitage's historical porcelain collection

Preservation of the Hermitage's historical porcelain collection

The Museum of the Imperial Porcelain Factory, managed by the State Hermitage Museum in St. Petersburg, is a unique place where the rarest works and works of art are kept. The porcelain collections contain exhibits that reflect the history and culture of Russia for several centuries. One of the historical gems of the museum is a series of porcelain figurines called "Nationalities of Russia", created in 1907-1917 by the author P.P. Kamensky. The collection has no analogues in its unique design and technique. Despite the quality and durability of the porcelain products, time and circumstances can cause irreparable damage to the exhibits. That is why one of the tasks of the Imperial Porcelain Factory is to preserve and recreate the collection. It was performed using modern 3D scanning techniques. The project was implemented jointly with the State Hermitage Museum and the Kiberon Group company, professionals in the field of 3D technologies.

There are 74 figures in the collection, which range in height from 36 to 40 cm. The Kiberon Group had the task of digitizing 28 figures: after processing the scan results, their three-dimensional models were prepared to create a digital archive of the collection. The same 3D models were used to create copies of gypsum polymer sculptures through 3D printing. A 3D scanner of the "PRO" line from RangeVision, a leader in the development and production of professional 3D scanners and related software in Russia, was used to digitize the figures. Cyberon Group specialists conducted 3D scanning on the museum's territory.

Anna Ishchenko, a 3d designer at Cyberon Group, spoke about the difficulties she faced in the process of digitizing porcelain figures.:

"The whole complexity and responsibility of the project was as follows:

The sculptures are over 100 years old. Any tactile manipulation of them was excluded. The entire process took place in the presence of museum staff, and any movement of exhibits was carried out with their help and under their supervision.
Most of the sculptures in the painting are black or even in dark blue or black color gradations. Dark colors have a poor reflection coefficient, which can lead to the scanner simply not "seeing" the object. This is the specifics of the technology. Not every 3D scanner has the ability to scan dark and black objects.
The porcelain material has its own glossiness and luster, which greatly complicates the process. Usually, shiny objects are coated with a matting spray before 3D scanning. But in this case, its use was not possible due to the age and value of the figures.
To create copies as close as possible to the original, scanning with high accuracy was required. In this regard, the sculptures were scanned in sections, not in their entirety."

How was such a difficult task accomplished?

The RangeVision "PRO" 3D scanner is customizable: it has four scanning zones for objects of various sizes. This made it possible to choose the optimal area in terms of the size of the object and the required quality of the final model.The surface of the sculptures was digitized in the second scanning area, the size of which is 300*225*225 mm. At the same time, the 3D resolution was ~ 0.17 mm. To simplify the task and due to the limitations on manipulating sculptures, a turntable was used for scanning. The object on the turntable rotated 360 degrees in 12 turns.

It was possible to achieve the maximum amount of information about the object for the light figures by making three groups of scans:

The first group of scans was captured with the scanner pointing from bottom to top, at an angle of 45 degrees;
The second one is at a 90-degree angle (scanning the middle of the sculpture);
The third is when the scanner is directed from top to bottom, at an angle of 45 degrees.

There were 6 such stages for dark and black-colored figures. The situation with figures in black/dark gradations was complicated by the fact that for successful scanning it was necessary to "illuminate the object", thereby obtaining a reflection of light from it. But in addition to the black color, there were also light shades in the painting (face, hands, patterns on clothes). The result was achieved thanks to the variable exposure settings of the RangeVision 3D scanner. The scan was repeated at standard exposure settings and with exposure increased by 2-3 times. This eliminated the "over-illumination" on the object that occurs when lighting porcelain, in conditions that do not allow the use of a matting spray. For sculptures with very complex, deep details in clothing, additional scanning was performed in the supine position of the object, in which the scanner could "see" the folds and depressions.

"As a result of the work, we received 4-5 groups of scans for light shapes and 10 for dark ones. A meaningful and convenient amount of information for post-processing," says Anna.

After digitization of the exhibits, post-processing of the results was carried out. The initial stitching and processing of the scans took place in the scanner's bundled software, RangeVision ScanCenter, which allowed combining groups of scans in automatic mode, which accelerated and facilitated the work. In the presence of groups with repeating geometry, the scans were combined manually point-by-point. The final preparation of the models and fitting to size, taking into account the shrinkage of the materials of further production, was carried out in the Blender program. As a result, 3D models in the STL format were obtained.

The gypsum polymer copy obtained by printing on a 3D printer was used to create a plaster mold, which was refined by the artists of the Imperial Porcelain Factory, taking into account modern technological features of production. Then the future product was cast into these molds and subjected to a double high-temperature firing.

The final stage of replica creation is the exact copying of the painting from the original museum. The copying of the sample and the subsequent painting of each product are carried out manually in the workshop of highly artistic products, taking into account the color nuances and the smallest details. Thanks to the professionalism of the sculptors and artists of the Imperial Porcelain Factory, the experience of the specialists of the Kiberon Group company, and the high-precision RangeVision 3D scanning equipment, it was possible to carry out a large-scale project to preserve and recreate the collection of the "Peoples of Russia", significant for the history.

Using a 3D scan of an actress when creating a commercial

Case study: Using a 3D scan of an actress to create a commercial

Briefly: An advertising agency used a 3D scan of the actress to advertise a medical product

Task: Creating a 3D model suitable for special effects and animation

Tools: Calibry 3D Scanner, Calibry Nest software

The result obtained: High-resolution 3D scanning data that was used to create the video

The modern entertainment industry (cinema, television) is largely dominated by digital technologies. We're not even talking about visual effects - it's long been a familiar part of the filming process. The next stage that the industry is moving towards is virtual actors. Combining real actors with their 3D models opens a new page in the entertainment industry.

The Robilant Associati agency has asked our partners in Italy, 3DiTALY, to digitize the actress. They needed to scan her face and hands, as these were the parts that were supposed to be shown in the frame.

The work was carried out using the Calibry 3D scanner, as it allows for fast on-site scanning without special training (unlike photogrammetry). The data was processed in the Calibry Nest program.

Retopology and animation were performed by 3D VFX/CGI specialist Agostino Davilla. The post-production was done by TEX Srl.

In October 2022, the commercial was shown on television. The video advertises an Afterapid medical device for oral hygiene, designed to treat ulcers. The action takes place in an empty red room full of motionless people. Laser beams scan them, and as soon as they identify a problem in one of the characters, a woman, the situation changes. Instead of the previous image, a 3D reality appears with a digital copy of the woman in the frame. A close–up shows the affected area - the lip with a sore that needs to be treated. After using the spray, the situation in the room changes: the alarming red light goes off and the room turns white. The viewer feels that the advertised product will bring immediate relief.

]]> Installing the Škoda Felicia engine in the LOISE-967 https://rangevision.com/en/application/cases/7027/ Thu, 06 Nov 2025 00:00:00 +0300 HELIX Design and modeling by autocast 3D scanning and modeling helped to realize a complex project to install a powerful engine in an old amphibious vehicle.

Installing the Škoda Felicia engine in the LOISE-967

Sometimes, sanctions pressure, lack of spare parts and documentation force us to look for non-standard solutions to keep critical equipment in working order…

And sometimes you just have a LoIS-967 — and you really need to cram a Škoda Felicia engine into it. Just need to.

The situations seem to be different, but the approaches and technologies used are the same.

Okay, not "just necessary" — there is also a technical justification. A carburetor engine from Zaporozhets was installed from the factory in the LoAZ-967: not the most efficient, powerful, lightweight or reliable choice for a floating transporter vehicle.

The Škoda Felicia engine is an injection engine: more compact, lighter, and even more powerful, more economical, and more reliable. The replacement is reasonable and logical.

But with approaches and technologies, everything is serious and without irony. Yes, in this article we will talk about the car of the 1970s, which you need to fit the engine of the 1990s. But in their place, they could just as well be, say, a Swedish-made screw compressor from the 2020s and a Rogachev electric motor from the same decade. The point is not the age of the units and mechanisms, but how to accurately and quickly connect what was not designed to work together.

The task for the ScanPro 3D specialist sounded extremely simple: to ensure the installation of the Škoda Felicia engine in the LOISE-967. Only the engine must be replaced — the gearbox remains native, from the LoISe.

Двигатель и маховик ЗАЗ

Extremely simple, but! The LoIS in which the new motor needs to be installed is not yet available. Only the second engine from LOISE (without gearbox), the engine and the Skoda gearbox are available.

In fact, the specialist faced several tasks at once.:

- to develop a 3D model of the transition plate for docking the new engine with the native gearbox;

- perform a virtual fitting of the motor and gearbox in the engine compartment and find their optimal relative position;

- design new engine brackets and landing elements on the power elements of the body.

The original design of the LoISe in places, to put it mildly, does not shine with thoughtfulness: the motor is attached exclusively to the gearbox and, according to the factory designers, simply "hangs" on it. This is a controversial decision that will also need to be dealt with.

Scan: the starting point for the entire project

First of all, the key surfaces were scanned.

The Felicia gearbox was scanned to determine the location of the starter on the adapter ring and to determine the location of the crankshaft sensor.

The Škoda Felicia checkpoint has been prepared for scanning: a matting spray has been applied and magnetic and volumetric markers have been placed.

The three-dimensional model of the Skoda checkpoint has all the surfaces and dimensions necessary for fitting

The Skoda flywheel was scanned to determine the desired thickness of the transition disc (looking ahead, the location of the slots for the crankshaft sensor was taken from it, but more on that below), the flange and mounting zones of the Škoda engine and similar sections of the native V—shaped Zaporozhets to combine all the mating parts.

Škoda Felicia flywheel and its digital copy

Scanning the clutch pressure plate ZAZ

Without all this data, there is no virtual assembly, no precise alignment of the axes, no gap calculation.

Skoda engine housing: it is enough to scan only its surface, which is connected to the gearbox

A RangeVision Helix handheld 3D scanner with a resolution of up to 0.15 mm was used to collect the geometry. However, in this project, most surfaces were scanned with a resolution of 0.3-0.4 mm: there were simply no small threads, grooves, or complex profiles requiring maximum detail. In this project, excessive point density is not needed: it will only slow down processing without increasing accuracy in solving the task.

Virtual Assembly: where everything should come together

After receiving all the scans, the most crucial part began — the virtual docking. A scan of the gearbox from Škoda was taken as the starting point. The goal is to align the engine, flywheel and gearbox strictly on the same axis, precisely align the mounting holes and choose a mutual position in which the starter will stand perfectly.

The surface of the LoISe motor and the Skoda flywheel, which must match

The area on the cylinder block turned out to be particularly delicate: to make room for the starter, it was necessary to carefully "chew out" part of the aluminum housing, but at the same time in no case touch the oil channels and preserve the threaded holes for the studs.

Determination of the central axis and alignment of the mounting holes with each other

It was working with accurate 3D models that allowed us to analyze the relative position of all components in advance, select the optimal geometry, simulate a CAD model for production and avoid mistakes - even before the first cutter touches the metal.

Fitting the LoISe gearbox to the Skoda engine

Transition ring: an experiment in steel

Based on the approved virtual assembly, an adapter ring was designed — it will connect the Skoda motor to the Luaz checkpoint. The structure is made of three parts: two of 5 mm steel and one of 4 mm, welded with subsequent welding of pins.

Solid-state adapter ring model: perfect matching of the mounting holes

This is an experimental sample, the purpose of which is to verify the correctness of the 3D model in reality.

The experimental adapter ring has been manufactured and is awaiting fitting

By fitting the ring, it was possible to determine exactly where to saw the Skoda motor for the new starter location: now it will look the other way relative to the native configuration.

It also became clear that the installation of the crankshaft sensor according to the factory scheme is not possible. The solution?

Transfer the reference disc from the flywheel to the front pulley. Everything has already been scanned, and designing the reference disk did not take much time. The test sample was cut from two halves of 5 mm steel and sent to assembly.

Build and go ahead — to launch

The final assembly is underway, and an experimental launch will take place in the near future. If the engine "comes to life", ScanPro 3D will begin the next stage: scanning the engine compartment and designing new brackets for attaching the motor to the LoISe spars. After all, hanging on a checkpoint is, of course, brave ... but not reliable.

We will talk about this stage of work in a separate article.

3D scanning makes it easier to create art objects

3D scanning makes it easier to create art objects

3D scanning technologies are great for learning and creativity. They create exact virtual copies of almost any objects. These copies can be modified, combined, and used in real time in various fields of visual art, or transformed into new real objects with different properties and materials.

Teachers of Russian art universities often ignore the potential of 3D modeling technologies. They consider only manual work to be truly creative. This prejudice restricts students (and in the future, artists) and does not allow them to take a broad look at the possibilities of the material and their own. In addition, there is a gap between the concept "in the head" and its implementation in practice.

But there is a different approach in art circles. Ivan Kozitsyn, a senior lecturer at the Stieglitz Academy (formerly Mukhinka, one of the oldest art universities in Russia), shared his experience of using 3D models in his work with us. His methodology shows that 3D scanning of prototypes and their computer modification simplify and accelerate the creative process. The master creates 3D models using a RangeVision 3D scanner, and his students produce finished products using CNC machines and 3D printers.

A work of decorative and applied art is created in several stages. First, a problem is posed, and a conceptual solution is sought for it. Any concept needs to be embodied in the material so that the master can visualize and refine it or even radically rework it before creating the final version. Artists call such a "probe" a protomodel.

Traditionally, protomodels are made and adjusted manually. It takes a lot of effort and time. With 3D visualization technologies, prototypes can be refined on a computer screen, compared, and combined. This significantly saves the artist's time and effort. It is also important that 3D technologies offer more opportunities for creativity and the implementation of new ideas.

An example of using a 3D scanner in an educational project

The method of using 3D scanning in the creation of works of art, which Ivan Kozitsyn teaches his students, will become clear on the example of one student's work. Her goal was to create a traditional decorative and applied art object, but using a 3D scanner and a CNC milling machine. The work was supposed to show how much easier and more flexible the creative process becomes with them.

At the first stage, the student manually molded a flat model out of plasticine. The main requirement for it was to form a prototype without axes of symmetry. This prototype was then scanned with a RangeVision 3D scanner, and the built-in program stitched individual scans into a single point model, followed by translation into a triangulated one. At the same time, the defects of hand molding were intentionally left to make the product look natural.

At the next stage of the work, the students chose the optimal compositional solution, using the well-known Osborne questionnaire to activate their creative search. They asked questions like "What can be changed, reduced or reflected in the object?" and they went over the possible options. The ZBrush program was used for visualization, which allows you to change the model in real time. This significantly accelerated the search for the best artistic solution, because students did not have to sculpt a new protomodel manually every time or vary it solely in their imagination.

As a result, the optimal composition of the object was found in the shortest possible time. A CNC milling machine has cut a model out of plaster. At the same time, manual processing became the last stage of the work anyway — the process is automated, however, a small human involvement is almost always necessary. The electroplating method was used for the final treatment: the gypsum part was coated with a thin layer of metal. The metal replica was then gilded. The finished product was named the "Scythian-style gold breastplate."

The described process of turning a project into a finished decorative object differs depending on the type of product and material. Sometimes a trial 3D model is created from scratch directly on the computer. However, such "purely computer" models do not look so natural — symmetry violations and other subtle flaws of the "real" prototypes make them more attractive and unique. This uniqueness is especially important for decorative objects.

The work of the Academy's students shows that translating a prototype into a 3D model and refining it in a virtual format is much faster and easier than making various versions manually using only imagination. At the same time, the role of the artist's creativity is not lost — the technique only takes on routine tasks.

This time they created a sculpture dedicated to firefighters, rescuers and vigilantes who took part in extinguishing forest fires in the summer of 2010. A Calibry 3D scanner and a 3D printer specially developed by Parc3D for metal printing were used in the manufacture of the sculpture. For more information about this project, see the article "Using the Calibry 3D scanner in the production of metal sculpture using a 3D printer."

Monument to the fires of summer 2010

The summer of 2010 was remembered for the large-scale fires that covered a total of twenty regions of the country. In some areas, the flames were coming so fast that people barely had time to leave their homes.

The sculptural composition dedicated to these events consists of a welded background structure and two figures. The main character is a firefighter who, restraining the onslaught of flames, covered a fawn (a symbol of wildlife).

Just like in the previous project, the human sculpture was created using 3D technology. A man in a firefighter's uniform was digitized with a Calibry 3D scanner. Then the model was printed on a 3D printer. The fawn was created in Zbrush, and the wall was created in Fusion 360.

3D models of ancient artifacts or digital archaeology

Creating a template for cutting the brain using a 3D scanner and a 3D printer

In the new Digital laboratory of the Institute of Archeology and Ethnography of the Siberian Branch of the Russian Academy of Sciences, scientists scan ancient stone tools, animal skulls and bones of primitive people, obtaining an accurate three-dimensional image with high resolution. The digital laboratory's electronic library contains hundreds of archaeological artifacts. Experimental and GIS modeling, tracological methods, and mathematical statistics are used here to study the material culture of ancient communities.

The finished 3D model becomes part of the collection documented in this way, which can then be shown to all interested parties without disturbing the physical original. The very possibility of creating and transmitting electronic copies of archaeological material is a huge step towards collective research. The digital model of the stone tool can be sent by e-mail to colleagues for joint study. Thanks to the emergence of digital archaeology, many researchers from all over the world can see with their own eyes and even hold unique artifacts in their hands (after printing on a 3D printer).

The technology of creating a three-dimensional model allows you to magnify the image many times for more thorough research and even "cut" the electronic version of the find into thin layers, make various measurements (metric, volume of the artifact, center of gravity). All of this was unavailable until recently. The mammoth tusk figurine discovered at the Tourist-2 monument two years ago was scanned, and the staff of the IAET SB RAS digital laboratory managed to restore its lost parts, reconstruct its original shape, determine the direction of the holes and calculate the center of mass. It turned out that the object was sewn onto clothes, since the holes were made diagonally and were located above the center of mass of the product, which ensured its stable position as a patch.

A digital archaeological artifact is an invaluable innovation for scientists. It can be used to carry out previously unavailable research. So, having measured thousands of coordinates, it is now possible to compare in shape both stone tools from different archaeological sites and even from different continents, as well as anthropological and paleontological finds. The main advantage of such an analysis over other humanitarian studies is its verifiability. If another scientist examines the same 3D models, he will get exactly the same result.

This method is relatively new in world practice with a high degree of accuracy and allows analyzing artifacts and bone remains from all periods and territories: from the Paleolithic to the present. An exact duplicate model of any artifact can be made using a three-dimensional sample, for example, for display at an exhibition. This is especially useful when it comes to fragile items or anthropological materials that require high DNA preservation for genetic research.

The central hall of the laboratory is decorated with two domestic Range Vision scanners – compact, portable and more powerful, stationary. They are mounted on tripods opposite the table, on which stands a small pedestal (turntable) for the artifacts under study – a small elevation with a photo frame – a soft mount made of elastic mass. The portable scanner has already managed to visit France, where the artifacts found during our field work at the Jonzac Neanderthal site were scanned. Photogrammetric studies at this parking lot were performed by Svetlana Schneider, an employee of our institute.

"The scanner is separately calibrated for artifacts of different sizes, the average number of images to create a model is 12-13," explains Pavel Chistyakov, a researcher at the Digital laboratory. – Cameras are aimed at the subject from different angles. They capture the geometry of an object and its texture. Before scanning, the projector applies a moving chiaroscuro grid to the object, and the camera captures this grid and builds a digital model of the object's surface from it. The accuracy and detail of the images is from 0.15 to 0.04 mm.

Researcher Vasily Kovalev joined the Digital Laboratory from Novosibirsk State University, where he worked on 3D modeling in the Laboratory for Interdisciplinary Research of Paleolithic Art in Eurasia.

"One of the applications of 3D reconstruction is the study of petroglyphs,– explains Vasily Kovalev. – Using photogrammetry and 3D scanning, it is possible to obtain a digital copy of the surface of drawings with high detail. Information about the technology and morphology of petroglyphs can be used for their relative dating. Together with Lidia Zotkina, an employee of IAET SB RAS, we automate the classification of traces of various types of tools on the surface of petroglyphs. With the help of a special program, you can automatically distinguish the 3D relief of the embossing applied by a stone or metal tool. A joint article was recently published on this topic.

The main goal of the laboratory is not to limit itself to 3D modeling for fixing or visualizing objects, but to move on to solving research problems using high–resolution volumetric models," an employee of the laboratory shared his plans. – Scientists have the opportunity to analyze the shape of stone tools, comparing them according to a number of metric parameters, characteristics of the faces. This allows you to avoid subjective assessments and data.

The head of the Digital Laboratory, Ksenia Kolobova, Doctor of Historical Sciences, said that 3D modeling is widely used in archeology all over the world. The technology began to be used about 20 years ago to document archaeological sites from an individual artifact to an entire monument.

– A virtual three-dimensional model created during excavations allows you to capture and save all information about the spatial characteristics of the archaeological site under study much more accurately than text, drawings and photographs. Laser scanning, structured illumination technology, and photogrammetry can be used for 3D field fixation.

DigiT is one of the first archaeological laboratories in Russia, where they are engaged in the study of scaled three–dimensional models. Here they study objects of ancient art from the Paleolithic and the Bronze Age, stone and bone tools from the Paleolithic and Neolithic, ancient tools for processing raw materials, ceramics from the Neolithic and the Bronze Age. With the help of various tools, lost fragments of artifacts or bones are reconstructed, as was recently performed by Chinese colleagues who worked with the Denisovan man's jaw, discovered on the high Tibetan plateau. Accurate measurements make it possible to conduct high-level research and, in combination with tracological studies, reconstruct the function of artifacts. Comparing the shape of stone tools and bones can provide researchers with information about the most likely migration routes and possible interactions of ancient people, about human population dynamics and animal species diversity.

The development and introduction of modern technologies into production are carried out as part of the implementation of scientific and technical projects in accordance with the national project "Science", which was developed in accordance with the May decree of the President of the Russian Federation. Its implementation period is from October 2018 to 2024. According to the goals of the national project, in 2024 Russia should become one of the five leading countries in the world engaged in scientific research and development in priority areas of scientific and technological development.

We would like to thank the specialists of the Digital laboratory of the Institute of Archeology and Ethnography of the Siberian Branch of the Russian Academy of Sciences and Vasily Kovalev personally for the material provided.

]]> Rebirth of a Legend: 3D scanning of the Buran spacecraft https://rangevision.com/en/application/cases/2253/ Fri, 23 Jan 2026 17:52:00 +0300 HELIX Reverse engineering museum business A laser handheld 3D scanner helps prepare the spacecraft for a full-scale restoration.

Rebirth of a Legend: 3D scanning of the Buran spacecraft

Nothing less than to scan the Buran spacecraft. This is exactly the request for advice that our Nizhny Novgorod partner and client Dmitry Ulybin, an expert in 3D scanning and reverse engineering, addressed to us. Without hesitation or delay, we rushed to Verkhnyaya Pyshma to take a direct part in the scan, because how can you miss the chance to touch the legend!

January, Ural, "Buran"

Verkhnyaya Pyshma is a small industrial town north of Yekaterinburg. This is the heart of the Ural Mining and Metallurgical Company, but the city is known for more than that. The Museum Complex of Civil and Military Equipment, established in 2005, is located here. This is probably the largest, most detailed and well-organized permanent exhibition of domestic and foreign equipment: four exhibition buildings and an extensive open-air exposition are located on an area of 13 hectares. The museum’s collection includes 15,000 exhibits, including 1,500 samples of military and civilian equipment.

This year, the museum plans to add a significant exhibit to its exposition in every sense. This is the only surviving flight copy of the Buran spacecraft in Russia. The space shuttle, which is currently in a rather depressing condition, will be completely restored and placed in a new pavilion built specifically for it. But first you need to restore a significant part of its body.

The legendary orbital shuttle Buran made its first and only flight on November 15, 1988. It was a real breakthrough in world space exploration, which could have been the beginning of a new era of space exploration. To date, no one has been able to repeat the achievement of Soviet designers — an automatic return spacecraft. Unfortunately, in 1993, after the collapse of the USSR, the program was finally curtailed.

Within the framework of the Energia—Buran program, only three flight ships of this type were produced. Only the first of them was called "Blizzard": the second was "Storm", and the third — the hero of this story — was called the Product 2.01 "Baikal".

The spacecraft arrived at the Museum Complex in August 2024. His transportation from Moscow to Verkhnyaya Pyshma itself makes for an exciting adventure film: on a barge along the canals of Moscow, then along the Volga through Nizhny Novgorod and Kazan, then along the Kama River to Perm, and finally on tractors along bypass roads to Verkhnyaya Pyshma.

The preparation of the multi-stage spacecraft restoration project took several months. Due to the fact that the Buran project was secret, the design documentation and drawings are almost completely missing. The only reconstruction option is to create a complete digital copy of the shuttle. Based on the data obtained, the missing parts will be designed and manufactured: the external elements of the main engines and control engines, the leaf of the nose landing gear, part of the glazing, the nose cone and the wing edge fairing.

Lasers in the snow

According to Nikolai Rezinsky, director of the Museum Complex, the restoration of the Buran is a unique project. Almost no one has ever tried to restore space technology before, there are only a few such specialists. At the same time, the museum plans not only to create a mock-up of the shuttle, but to restore its entire structure as completely as possible, including the original components and assemblies, instruments, and interior, so that visitors to the exhibition can fully experience themselves as pilots of a real orbital shuttle.

Yaroslav Portmanov, chief specialist for the restoration of the Buran, did a great job collecting all available technical information about the shuttle from various design bureaus and institutes. But still, many structural elements will have to be reinvented based on the existing design — for example, to recreate the lost hatch flap of the landing gear compartment.

The first stage of the reconstruction is a 3D scan of the hull and wings to create a basic digital model of the Buran. It was in the scanning that we were lucky enough to take an active part.

The reconstruction plan is very tight, so the 3D scanning of the Buran began as early as possible — on January 25, 2025. By spring, the museum’s specialists are going to install the wings and begin further restoration.

Ural January turned out to be invigorating: snowdrifts, freezing temperatures of -15 and a piercing wind. The museum’s specialists provided the most comfortable conditions possible: they cleared the snow, erected forests and installed heated tents.

Helix handheld 3D laser scanners and RV 3D Studio proprietary software were used to scan Buran. We scanned simultaneously with two scanners: the data was collected at different sites, including on different floors of the scaffolding, and then the scans were combined in a program to make sure that all the necessary geometry was collected.

Scanning the Buran hull

Before scanning, the shuttle body was glued with 6 mm marks. The case is almost entirely made of titanium and aluminum, so it was impossible to use magnetic tags. According to rough estimates, more than 5,000 self-adhesive markers were manually applied to the Buran.

The scanning process itself took two full-time work shifts, despite the fact that the Helix scanners showed impressive digitization speed, despite the cold. The largest scanning object in terms of area was the rear end of the case measuring approximately 6×6 meters. I had to work on three-story scaffolding.

The Buran lacks a nose cone and a front landing gear compartment cover. They will need to be re-manufactured and installed in their rightful places. During the scan, we digitized the hatch and mounting brackets so that we could re-construct these parts.

Scanning the Buran's wings

In addition to the hull, the wings removed from the shuttle and folded side by side were scanned. Their dimensions are no less impressive than the body. At the same time, wings are complex structures with a variety of diverse elements and complex geometries. During the life of the Buran, the wings were removed and placed on it repeatedly, so the attachment points of the wings were partially damaged and deformed. Even the availability of complete documentation would not have allowed for the correct reconstruction of spare parts — a local adjustment was required.

The scanner’s mounting brackets came into focus. These are typical parts: it is enough to create a digital copy of one whole bracket to copy it and replace the damaged or lost ones.

In RV 3D Studio, the initial scan matching was performed right on the spot. Deeper processing was already done in a warm room without haste. All the assembled geometries fit perfectly within the accuracy specified by the customer.

Buran scan — results

The entire planned amount of work was completed in two days. We have scanned four large and critical parts of the object.:

wing attachment
points nose cone
front landing gear
rack tail section

Constructed and processed 3D models are an excellent base for designing mating parts and assemblies.

Further development of the project

The restoration work will take a whole year. During this time, the restorers will find the missing parts or at least the documentation for them, or they will create them anew. After that, the Buran will return to its original appearance: it is expected to be contaminated, locally repaired, and the interior will be completed.

The tasks of 3D scanning the spacecraft have not ended. In February 2025, we will go to scan again, this time the full—size Buran test stand, known as OK-KS (product 0.03). This is an almost complete replica of the real shuttle, which was used for ground tests before the actual launch. This model, located in Sochi on the territory of the Sirius Educational center, has been preserved as much as possible. It will become a "3D donor" for its brother Baikal: all the parts missing from the Ural shuttle will be scanned, primarily the stern with main engines and control engines.

We will continue to talk about the Buran restoration project in the next issues of the blog.

]]> Scanning a six-meter boat matrix in the field https://rangevision.com/en/application/cases/7037/ Fri, 26 Dec 2025 00:00:00 +0300 HELIX Reverse engineering shipbuilding DASCAN Laboratory specialists scanned the boat in difficult weather conditions using a Helix handheld 3D scanner.

Scanning a six-meter boat matrix in the field

Which is easier: send a six-meter heavy matrix of a boat to another city for scanning, or invite a specialist with a manual 3D scanner to your place? The customer decided the same way as you did, and invited the DASCAN Laboratory specialists directly to his facility.

The task was to accurately reproduce the shape of the existing matrix — the model was required for subsequent reverse engineering. For the convenience of scanning, the object was carefully placed outdoors, where the temperature had been around zero for a long time. During this time, the material shrank due to the cold.

Fortunately, the customer took this into account and warned in advance: the task is not to recreate the matrix in its original dimensions "one to one", but to accurately repeat its shape. Possible deviations from the original are not critical if all proportions are observed.

The scan was performed using a RangeVision Helix handheld 3D scanner. The brightness of the blue laser was enough to stop matting the surface. Data collection was further accelerated by reducing the resolution from 0.15 to 1 mm — there is no fine geometry on the matrix, and such detail was sufficient for the task. In addition, since the object is completely symmetrical, only half was scanned — with sufficient overlap for reliable binding. The second half was recreated with a mirror image.

To make sure that the material did not shrink further during the scanning process due to possible temperature fluctuations, individual areas were scanned twice — at the beginning and at the end of the work. The comparison showed that the sizes matched.

The whole process, including applying markers, took two hours.

Despite the "comfortable" conditions — night, a lantern and falling snow — when the equipment has to be warmed by hands and the optics protected from fogging, it was possible to obtain stable and complete data on the entire surface. After processing the point cloud, a ready-made 3D model was assembled, suitable for further reverse engineering.

With the Helix handheld laser scanner, such difficult tasks as scanning a black boat in the evening in the cold are solved quite simply. All you need is a supply of markers.

Recreating BMW 328 Roadster parts using digital technology

The automobile legend of the 30s

When it comes to the BMW 328 Roadster, there are always epithets like "legend" and even "motorsport icon" — and rightly so: of the 172 races around the world in which this car participated, it won 141.

Less attention is paid to the fact that the car had an extremely short production life — it was produced from 1936 to 1940. A total of 464 copies rolled off the assembly line, and even fewer were in the back of the roadster: 403 cars.

A little over 80 years have passed, and now the BMW 328 Roadster is no longer just a legend, but a historical value. In fact, it is a real artifact. Even if only ruins remain of a particular specimen, it is still of great importance ... and, of course, requires painstaking, careful restoration.

Fortunately, modern technologies — in particular, 3D scanning — make this task much easier.

Recovery from oblivion

In this case, only fragments of the frame and individual body parts fell into the hands of the restorers — there was a huge amount of work to restore ... almost everything, including the manufacture of missing frame elements.

According to the available references, the preserved parts were carefully positioned using a laser level — relative to each other and in accordance with the original geometry of the frame — and securely fixed in the desired position.

This allowed the FivCo 3D specialist, who is engaged in 3D scanning and reverse engineering, to digitize all the preserved original elements and recreate a complete frame based on them for subsequent manufacture.

3D scanning of fragments

The RangeVision Spectrum 3D scanner was used for scanning, pre-calibrated for the largest capture area. In this mode, it is able to digitize fragments up to half a meter in size in one scan, which is especially convenient when working with large objects. At the same time, the scanner retains high accuracy: the resolution is about 0.2 mm, and the error remains within the tolerance limits sufficient for manufacturing parts for subsequent assembly. This is the optimal balance between speed, scale and detail — exactly what is needed in restoration, where both the overall appearance and small design nuances are important.

Taking into account all the preparatory work (warming up the garage with a heat gun to stabilize the temperature, applying markers to the object and the limited space in the room), the scan took a little more than one working day. And it took about 20 hours to create the final CAD model, taking into account the customer's wishes, checking with the preserved archival drawings and adjusting to the original parts.

Project results

The specialist designed the missing frame elements, which perfectly fit both with the preserved original body parts and with the rest of the native frame — without fitting "by eye" and unnecessary tests.

The resulting models became the starting point for the customer in the search for a contractor to make exact copies of the lost parts and at the same time formed the basis of the entire restoration plan.

3D scanning has long been an integral part of car tuning, whether it's the restoration of vintage cars or the refinement of modern ones. It helps you quickly and accurately remove geometry from any object, so that you can recreate a detail later or adapt something new to existing shapes.

]]> Creating replicas of antique medals for the Russian Cultural Foundation https://rangevision.com/en/application/cases/2795/ Thu, 27 Mar 2025 16:09:00 +0300 PRO II museum business Reverse engineering The tactile replicas of the antique medals were recreated in plastic for an inclusive display so that visually impaired people could explore them.

Creating replicas of antique medals for the Russian Cultural Foundation

Our partner, 3Dtool, participated in the preparation of exhibits for the Rare Gift exhibition, organized by the Russian Cultural Foundation. Especially for the exhibition, they produced precise 3D-printed replicas of rare medals returned to Russia from foreign collections.

"Rare Gift" is a unique mobile inclusive exhibition

The exhibition "A rare gift. Stories of the return of cultural treasures from the collection of the Russian Cultural Foundation" was held in 2024 in three Russian cities: St. Petersburg, Pyatigorsk and Rostov-on-Don. It was visited by more than 48 thousand people.

According to cultural experts, it has become a good example of a competent and thoughtful approach to the inclusive design of exhibition spaces in accordance with current methods and tools for expanding cultural accessibility and creating projects adapted for visitors with different experiences.

The route of visiting the exhibition implied versatility and different types of interaction with it: exhibits that can be touched, sound accompaniment and typhot commentary, Braille, convenience for people of different heights and builds, right-handed and left-handed.

Medal Collection

The Rare Gift exhibition space consists of ten thematic sections. The exhibition includes reproductions of works by Aivazovsky, Repin and Levitsky, exhibits from the 1924 Russian Exhibition in America, archives and newsreels, replicas of objects belonging to famous people.

Replicas of four antique medals from the collection of the museum of the American society "Rodina", created by Russian emigrants in 1954 in Lakewood, New Jersey, were also on display. Their exact enlarged copies were displayed on the stand as tactile exhibits.

The tactile collection includes:

medal "For the accession of Peter the Great to the throne", made by engravers Yudin and Vechter;
medal "In memory of the Twenty-five years of work of the Imperial Moscow Society of Agriculture", created by engravers Klepikov and Utkin in 1845;
table medal "In memory of the birth of Tsarevich Peter Alekseevich", cast from a bronze alloy under Empress Elizabeth Petrovna in 1759 in honor of the birth of Peter I.;
The beard badge of 1705 is a kind of “receipt" for the payment of a tax on wearing a beard.

The reproduction of the replicas included several stages:

3D scanning of original medals;
scaling 3D models;
3D printing of enlarged replicas;
artistic processing of plastic medals.

3D scanning and scaling of original medals

3Dtool specialists used a high-precision 3D metrological scanner RangeVision PRO II to scan the original exhibits. The medals were carefully placed on an automatic turntable and scanned from both sides, and then the scans were combined in RV 3D Studio.

Optical 3D scanners are not always able to digitize dark and shiny surfaces, so objects are usually coated with a special matting spray before scanning. But it is strictly forbidden to put any substances on antique medals - you can't even touch them with your bare hands. Therefore, all hope was for a powerful blue light projector, which is equipped with a 3D scanner PRO II.

The scanner did an excellent job of digitizing the medals, transferring the smallest details of the exhibits.

After digitization, the 3D models were cleaned of noise and artifacts and scaled. For example, the size of the smallest exhibit, the Beard Sign, is only 23 mm in diameter in the original, but all replicas have been increased to 90 millimeters to make them easier to view and, if necessary, even explore by touch.

3D printing of enlarged replicas

All seven replicas were printed with photopolymer resins on high-precision 3D printers using LCD mask stereolithography technology. To speed up the process, several additive systems were used at once — 3DiY Rex 6K, Anycubic Photon Mono X 6K, Elegoo Saturn 3 Ultra and Phrozen Sonic Mega 8K S. The consumable material was the photopolymer Elegoo Standard Resin 8K.

Artistic treatment of replicas

Polymer models reproduce geometry exactly and are great for tactile study — but only tactile. To make the printed medals look as much like the originals as possible, they were sent for artistic revision to specialists who reproduced all the shades of the original metal texture, including scratches and traces of corrosion.

Project results

Thanks to 3D scanning and 3D printing, visitors to the Russian Gift exhibition were able not only to see, but also to touch the unique rarities, the originals of which are hidden under the glass of the showcase. And a fairly typical and understandable task for a 3D scanner - the replication of museum exhibits — has acquired a new meaning, becoming part of a big idea to create a new inclusive exhibition space.

3D scanning in the field of funeral services

3D scanning in the field of funeral services

3D scanners have long been widely used in the industrial sector, automotive and car tuning, medicine, high-end sports, art and cultural heritage preservation.

In the field of funeral services, 3D scanning is still exotic, although the prospects for this area are quite promising.

A few days ago, we were approached by a company that provides services for the installation of monuments, as well as cleaning and beautification of burial sites, Epitaph, with a request to digitize grave monuments. They need 3D models for two potential tasks: the introduction of a special constructor on the site, where it will be possible to choose the type, color and shape of the monument, and "try on" it in virtual space, as well as the use of models for CNC turning (instead of manual labor). The use for CNC is still in the project, but the company is currently working on a designer.

Initially, grave monuments were modeled in Zbrush. However, this method proved to be economically inefficient. If it makes sense to model simple shapes in sculpting software, then complex shapes take too much time and are expensive. Digitization of existing monuments with subsequent refinement makes it more economically feasible for the designer.

Scanning granite monuments requires skill, as a large area is flat and glossy. In order to orient the scanner in space, additional geometry was added. The glossy surface was selectively matted with a special spray to avoid excessive noise in the data and obtain a uniform point cloud. In cases where granite slabs were dusted due to natural causes, the spray was not used.

Scanning of each monument took less than 5 minutes. Post–processing in Calibry Nest takes about 10 minutes. Next, the finished 3D models will be simplified by the modeler to meet the technical requirements of the designer on the website.

3D scanning of the Vrubel fireplace in the Tretyakov Gallery

3D scanning of the Vrubel fireplace in the Tretyakov Gallery

Mikhail Alexandrovich Vrubel's work occupies a unique place in the history of Russian art. Formally, the artist belongs to the Art Nouveau era, but the special style in which Vrubel worked greatly distinguishes him from his contemporaries. Despite the fact that the artist used mostly dark or cold shades in his works, his works are emotional, expressive and lively.

The artist's creative interest did not end with painting canvases. The passion for ceramics arose in the life of Mikhail Alexandrovich in 1890, thanks to which stunning sculptures, high-reliefs, panels and decorative dishes made of majolica appeared in the history of Russian art. The heroes of his plots are epic heroes and characters of Russian fairy tales. One of the most iconic works of this period is the fireplace "Mikula Selyaninovich and Volga" from the mansion of M.F.Krivoshein in Moscow. In 1900, at the World's Fair in Paris, this fireplace was shown in the stylization of the Russian interior.

The fireplace has a rather interesting fate. In the 1960s, the mansion, where the famous fireplace was installed, was transferred to the jurisdiction of the Lebanese Embassy. On this occasion, the new owners carried out repairs and the bright fireplace did not fit into the interior. It was decided to dismantle it and transfer it to the Tretyakov Gallery for preservation.

However, the design feature of the fireplace did not allow it to be safely dismantled: it was originally designed as a tiled stove, and the cladding, valuable fragments of majolica, were interconnected with metal wire and fixed to the wall on lime-cement mortar. Unfortunately, it was not possible to remove the fireplace embedded in the wall without damage. Vrubel's fireplace was delivered to the Tretyakov Gallery in the form of fragments, some fragments were badly damaged, some were lost.…

The fireplace was put on permanent display in 2007 after the fragments of majolica were put back together.

In order to preserve the cultural heritage and simplify subsequent restoration work, it was decided to digitize the fireplace. The Calibry 3D scanner was used for this task.

From the point of view of 3D scanning, this object is not simple, since:

a significant part of the panels is flat, and most scanners can digitize an object thanks to geometric tracking ("clinging" to the irregularities, which should be sufficient);
The Vrubel fireplace is an object of cultural heritage and markers cannot be pasted on it (an alternative tracking option that is used when scanning objects with undefined geometry);
lack of electricity sources in the immediate vicinity;
Majolica ceramics are glazed and can glare at a certain angle. For many scanners, such surfaces cause difficulties when digitizing;
The Calibry 3D scanner has three object tracking modes: geometry, markers, and texture. In the case of the Vrubel fireplace, there are more than enough diverse and vibrant textures. The device's algorithms also allow you to scan shiny objects without problems, and high accuracy ensures that even the smallest details will be digitized.

The Calibry 3D scanner can also be fully portable, meaning it doesn't have to be connected to an external power source, but rather powered by a battery.

3D scanning for the Kursk Battle Memorial in Ponyry

On August 23, 2023, the grand opening of the monument dedicated to the 80th anniversary of the victory in the Battle of Kursk took place. The monumental sculpture of a soldier is the first part of the memorial. The final construction of the memorial complex is scheduled to be completed by May 9, 2025.

The Battle of Kursk is considered one of the largest battles of the Second World War. Even after 80 years, search expeditions continue to find shell fragments, soldiers' personal belongings and spent shell casings at the site of the fighting. There were several significant battles in the Battle of Kursk. And if the Battle of Prokhorov was immortalized in textbooks and monuments, there was undeservedly less attention to the battle on the northern facade.

In 2021, the Russian Military Historical Society decided to restore historical justice and perpetuate the feat of the heroes of the northern facade. An international project competition was announced, which resulted in two finalists by a small margin.

The first work of the sculptor Evgeny Vuchetich, which was planned for construction back in the 60s, was never realized. The master's latest project was decided to be implemented by his students.

The second finalist is the work of Andrei Korobtsov and Konstantin Fomin, famous for their sculpture of the Soviet Soldier at the Rzhevsky Memorial.

The authors decided to "perpetuate in stone" the first stage of the Battle of Kursk – the battles for Ponyri station. This station had a very important strategic position. To break through the front, the enemy launched 32 attacks with large infantry and tank forces supported by aircraft and hundreds of guns.

The sculpture of a soldier embodies the courage of Soviet soldiers. The monumental figure does not allow the encirclement to close, literally pushing the walls apart with his hands – the onslaught of the enemy.

As in the case of creating a sculpture of a Soviet soldier for the Rzhev Memorial, the authors used 3D technology. A sketch approved by the commission was scanned using a Calibry 3D scanner. The sculpture was scanned in exactly the same way as a 3D scan of a person: from top to bottom in a spiral.

The model was used for aerodynamic tests and the design of the frame on which the sculptural composition rests. The full-size sculpture was created in "soft material" parts, which were then cast in bronze, brought to the construction site and mounted directly on site.

More scans of the sculpture and photos from the workshop can be found in our Telegram channel.

Calibry 3D Scanner helped BMW upgrade for dAHLer

Calibry 3D Scanner helped BMW upgrade for dAHLer

Case study: The Swiss dAHLer tuning studio used the Calibry 3D scanner to customize and improve the aerodynamic performance of the BMW M240i and BMW G80.

Briefly: CHROMOS Group AG, a developer of innovative solutions in the industrial sector, shared an example from the practice of its client, a design agency designunity.ch , who in turn developed the project for dAHLer. The end customer (dAHLer) has upgraded the BMW M240i and BMW G80 series, improving the aerodynamics of the vehicles by adding a splitter to the front bumper. The project was carried out using 3D technologies, where a Calibry scanner was used to digitize the front of the car.

Task: The task was to obtain a high-resolution model of the bumper, which can later be used for reverse engineering. At the same time, the project costs should not be high.

Tools: Calibry 3D Scanner, Calibry Nest software, Rhino software, 3D Printer

The result: With the help of 3D technologies, solutions were found that best meet the customer's requirements: high-quality scanning data suitable for subsequent reverse engineering, while maintaining low costs by optimizing costs. The upgrade has already been successfully implemented for the m240i. The G80 is currently in line.

The Swiss company dAHLer has been manufacturing parts and accessories for BMW since 1996. dAHLer offers a wide range of tuning products for fans of the legendary brand: tilt-adjustable suspensions, sets of lowering elements, high-performance exhaust systems, forged wheels, interior details and much more. dAHLer prioritizes speed and power. As stated on the company's website, its goal is to "turn your production car into a real top-class car."

When we talk about maximizing speed, aerodynamic drag becomes a key issue that needs to be considered. Here, dAHLer specialists offer their customers to purchase body parts such as splitters, rear fenders, side skirts, diffusers and rear-view mirror covers, which allow the car to smoothly cut through the air.

The last two upgrades carried out by dAHLer were performed for the BMW M240i and BMW G80, where a Calibry 3D scanner was used to manufacture the front splitter.

The first part of the project, scanning, took place in the dAHLer showroom. A matting spray was applied to the front bumper of the car. This was enough for the Calibry 3D scanner to capture the geometry in high resolution. No markers were needed. The scan lasted about 40 minutes, starting with unpacking the scanner and preparing the workplace.

Several single bumper scans were performed. The post-processing of the data, combining the scans into a single model, took about 1.5 hours. After the work was completed at Calibry Nest, the second part of the project, modeling, began.

The design was designed in the Rhino program and included many stages of editing and adjustments. At the final stage of the design, 2-3 of the most successful works were selected. These prototypes were printed out on a 3D printer so that they could be "tried on" to a car and choose the most successful option. All the design solutions looked good on a computer screen, but dAHLer wanted to choose what would look best in real life.

After careful selection of prototypes, the final version was painted and attached to the bumper to take pictures of the car for the press.

After the final approval of the design and mounting fixtures, the drawings were sent to the factory to produce carbon fiber parts. The planned production volume is about 30 parts per year.

The BMW M240i already has a carbon fiber splitter, and the M4 model is temporarily equipped with a 3D-printed part.

According to the project participants, Calibry was chosen "because of its ease of use, accuracy, fantastic software, portability, robustness, and finally cost compared to other systems."

High-resolution scanners turned out to be expensive, which increased the cost of production beyond the planned. Most of the affordable devices did not meet the quality requirements. Calibry was chosen for the optimal balance of these two factors.

3D scanning for contactless analysis of works of art

The prototyping center of the St. Petersburg Technopark continues to use new technologies and scanning methods for an increasingly wide range of industries. Together with colleagues from universities, engineers plan to contribute to the preservation of cultural heritage sites, in particular paintings.

Painting is a significant part of the cultural heritage of mankind. Each of the canvases has its own composition. It can be painted in oil on canvas, pencil on cardboard, gouache on plywood, pastel on sandpaper. In any case, each of these objects is a complex arrangement of materials that are subject to environmental changes.

A non-invasive, non-contact method is needed to monitor the condition. Since works of art have high historical and cultural value, it is critically important to limit the physical impact on their surface. It is advisable to detect changes at the micro level before they become visually noticeable. This will help to avoid further destruction and identify the most suitable conditions in which the paintings should be stored, transported or put on display. To carry out the complex of necessary studies, 3D scanning was used.

Today, 3D scanning is used for high-precision measurements in industrial production, medicine, criminology, and now in the field of cultural heritage preservation. Modern 3D scanners allow you to obtain information about the geometry of the surface with a high degree of accuracy: from tens to hundreds of micrometers. This is quite enough to recognize changes in the condition of the canvases. The work carried out helped us to verify this in practice.

The objects of research by Anton Zhuravlev, an engineer at the Prototyping Center, and colleagues from SBGETU LETI were oil paintings. For example, one of them, from the collection of the Military Historical Museum of Artillery, Engineering and Communications Troops of St. Petersburg, was studied using a RangeVision PRO 3D scanner. The scan was performed with an interval of 4.5 years to compare two versions of 3D models of the same work. The software made it possible to combine the two models and, as a result of the overlap, a visualization of the change in the state of the canvas was obtained.

The differences in the surface condition of the painting are highlighted in colors. Two large areas of blue are particularly noticeable: at this point, the surface of the painting has become more prominent than before. The maximum standard deviation recorded in 2014 and 2019 is approximately 200 µm.

The experiment in practice confirmed the prospects of using optical 3D scanning to monitor the condition of oil paintings. This method helps to obtain quantitative information about the deformation of the canvas, frame and the surface of the canvas itself during storage under the influence of environmental conditions.

The technology has already been appreciated by the largest museums in the world. For example, the Metropolitan Museum of Art in New York actively uses its experience in the field of contactless analysis of paintings. A number of Russian museums have become interested in the work of the Prototyping Center's engineers, one of whose key tasks is to preserve cultural heritage sites for future generations.

The legendary Maserati 3200 GT car has been given a new lease of life thanks to the RangeVision Spectrum 3D scanner

3D technologies are widely used in automotive production at the design stage of new models. However, not only large automakers can use 3D scanners, but also specialists who are engaged in automotive repair and tuning. Using this equipment, it is possible to solve tasks of varying degrees of complexity: from digitizing individual parts, geometry control to the implementation of ambitious projects in the field of restoration and modernization of classic cars. We will talk about one of these projects in this article.

Restomod – new life for old cars

Restomod is a branch of car tuning that connoisseurs of classic cars of historical value are probably familiar with. The term restomod is formed from the fusion of two words restoration (restoration) and modernization (modernization) and refers to a car with a qualitatively restored body and upgraded units, due to which its consumer parameters are improved: comfort, handling, efficiency. To make the car perfect, it is being restored and upgraded using the latest carbon fiber parts and state-of-the-art technology.

The RestoMod 2021 project

Tomaso Trussardi, a famous Italian entrepreneur, decided to make his car dream come true by turning the iconic Maserati 3200 GT car into a real racing car with its inherent elegance.

Task: it was necessary to obtain a digital copy of the Maserati 3200 GT car for reverse engineering and subsequent modernization.

A functional RangeVision Spectrum 3D scanner from the Russian company RangeVision was selected for the implementation of this project. It is designed for professional digitization of objects of various shapes and sizes.

It is worth noting that the RangeVision Spectrum scanner has already shown its effectiveness in projects such as scanning body parts to create a replica of a Shelby Cobra car in a Machinator car repair shop and developing a Kawasaki motorcycle sports fairing with improved aerodynamic parameters.

Why was the RangeVision Spectrum 3D scanner chosen for Tomaso Trussardi's project?

High scanning accuracy up to 0.04mm and 3D resolution up to 0.06mm
Using structured illumination technologies, it is possible to create color-detailed 3D models with the transfer of complex geometry and the smallest details of various objects: from miniature to large-scale
Three scanning modes allow you to work with different types of objects.
Convenient RangeVision ScanCenter NG software for scanning and processing models.

Creating a digital copy

The first stage of the transformation of the legendary Maserati 3200 GT was the scanning of the car with a RangeVision Spectrum 3D scanner. The partners of RangeVision INKAY Technology S.r.l scanned the body, dashboard, doors, trunk, hood and engine compartment.

The car was then mounted on a lift. To open access to the chassis, suspension parts and scan them, it was necessary to dismantle the bodywork, engine and wheels.

As a result of data processing, an accurate digital 3D model of the car was obtained, which had the necessary symmetry. Based on this digital copy, the Maserati 3200 GT car was recreated in its original form.

The RestoMod 2021 project has been called a revolution in the use of composite materials in the production of racing cars. He was appreciated by global brands of high-performance supercars and motorcycles.

It must be said that 3D scanners have made a great contribution to the development of car tuning and repair. They can be used to scan parts and body parts, and then produce them on a 3D printer. This is especially true for small car service stations and private specialists who perform car repairs and maintenance.

Car tuning using 3D technology

A PICASO client has ordered the production of a custom snorkel from the company, which is needed for off-road driving.

Case study: designing a car snorkel using 3D hardware and software

Briefly: PICASO, together with THOR3D, improved the car's body structure (design and installation of a snorkel) using 3D technologies in their work.

Task: Creation of an exhaust air intake for an off-road vehicle for its operation in off-road conditions.

Tools: Calibry 3D Scanner, Designer XL 3D printer, Calibry Nest software, Geomagic Design X and Siemens NX.

The result: a fully functional design that performed well in off-road driving conditions.

A PICASO client has ordered the production of a custom snorkel from the company, which is needed for off-road driving. The main task of the removed air intake is to protect the engine from a water hammer, which can lead to serious engine failure. The design of the snorkel assumes that all water and dirt entering through the nozzle, hitting the walls, flows out through special slots.

There are many ready-made solutions on the market, but the client wanted the design of the structure and the production itself to be in a single copy. For such solutions, the easiest way was to turn to 3D technologies.

First, the specialist scanned the car body with a Calibry 3D scanner. Since the client wanted to get a complete model of the car, it was scanned in its entirety, but in the future, only the part of the body to which the snorkel is attached was needed to work. Scanning of the required part took 10 minutes, and post-processing in Calibry Nest took 15 minutes.

Calibry can scan dark and shiny objects, but since the data was supposed to be used in reverse engineering, to obtain the most accurate parameters, the car body was wrapped with a special spray and markers were applied.

After designing the air intake and comparing the resulting model with the CAD original, the snorkel was printed on a Designer XL 3D printer made of plastic. The design was successfully installed in the body and tested by the owner.

]]> Dinosaur footprint scanning in Poland https://rangevision.com/en/application/cases/7058/ Wed, 01 Sep 2021 00:00:00 +0300 CALIBRY Digital archiving and visualization museum business Using the Calibry 3D scanner to digitize the largest dinosaur paw prints ever recorded in Poland.

Dinosaur footprint scanning in Poland

Dinosaur footprint scanning in Poland

Case study: Using the Calibry 3D scanner to digitize the largest dinosaur paw prints ever recorded in Poland.

In short: perfectly preserved dinosaur footprints were found in sandstone slabs, which weighed on average from several hundred kilograms to several tons. It was difficult to transfer them from the clay mine in Borkovica, so a portable 3D scanner was used to digitize the prints for further paleontological research.

Tasks: digitization of fossils (footprints) to obtain information about dinosaurs.

Tools: Calibry 3D scanner, Calibry Nest software.

The result: 3D scans of the fossils allowed paleontologists to record at least seven different dinosaur species in the Mazovia region (Poland). They also helped in the study of their behavior.

Until recently, it seemed that Poland had few chances for impressive paleontological discoveries. However, the summer of 2021 changed that. Geologist from the Polish Geological Institute (National Research Institute), Professor Grzegorz Penkovsky, Ph.D., and Dr. Grzegorz Nedzwedzky from Uppsala University (Sweden) have discovered numerous well-preserved traces of carnivorous and herbivorous dinosaurs. The footprints date back to the Jurassic period and have been preserved on sandstone slabs in a quarry in Borkovica.

The quality of the preserved dinosaur footprints is impressive; they are clearly visible to the naked eye. The findings point to a complex fauna that lived in the area 200 million years ago. The largest carnivorous dinosaur footprints ever recorded in Borkovica are almost 40 cm long.

"In order for the fossils to be so well preserved, a special chain of events had to occur in a short period of time: the fragmentation of the reservoir and the exposure of the clay bottom, the dinosaurs' exit to the still-wet, plastic soil, the drying of the substrate and the hardening of the tracks (as evidenced by cracks from drying), then rapid flooding of the territory and equally rapid the surface was covered with sediment from the sandbank of the overlying barrier, which turned the tracks into casts," comments Prof. Grzegorz Penkovsky.

Rare fossils are the subject of geological and paleontological research. Unfortunately, sandstone slabs are difficult to transport for further analysis, as their weight varies from several hundred kilograms to several tons. In addition, many parts of the fossils cannot be extracted without damaging the object. That's when 3D scanning comes to the rescue.

The footprints were scanned by a Calibry 3D scanner. It is lightweight and easy to operate - a great choice when you need to work on site. The high-resolution data allowed the experts to capture the fossils with maximum detail.

The study of fossilized footprints is of great importance to paleontologists, as it helps to learn about the behavior of ancient organisms. For example, footprints and footprints can tell scientists whether dinosaurs moved in herds or alone, how they defended themselves from predators (for example, they kept their cubs in the center of a group). Paleontologists can estimate the weight of individuals, their gait and speed.

"You can read their behavior and habits from the footprints left by dinosaurs. So, in Borkovica we have traces left by dinosaurs running, swimming, resting and sitting on muddy sediments, as well as many interesting biogenic structures, probably related to various types of life activity of dinosaurs that lived here (for example, traces of feeding or burrowing into sediments). The finds of footprints indicate an exceptionally complex fauna that once inhabited this area." - Dr. Grzegorz Niedzwedski comments.

3D scanners are widely used in paleontology to analyze, document field objects and preserve finds. They also make the discoveries of scientists more accessible to museums and a wide audience. Thus, several surfaces with paw prints found in Borkovica are of the highest value not only from a scientific point of view, but also as an exhibition object.

The prospects for research in Borkovica are promising. Administrative procedures are already underway to secure the facility.

3D scanning of exhibits of the museum's historical and artistic complex

Remote work with artifacts, increasing the speed of scientific information exchange and virtual museums, allowing you to get acquainted with collections "closed" in museum repositories without leaving home? All this is possible thanks to modern 3D technologies, which provide new opportunities for the preservation and study of cultural heritage.

3D scanning technologies have been used for a long time when working with historical values, and one of the directions is the creation of virtual expositions.

World museums already offer virtual tours that make it easy to learn about the history of a country or region from the comfort of your home or office. There are many reasons for a virtual visit: the lack of time for a trip, and the desire to get acquainted with the museum's exposition in advance before visiting it, or to study individual exhibits in detail without haste at home. Some museums may be located in remote or hard-to-reach places, in such cases virtual visits become an alternative means of studying history.

Unlike physical space, virtual space allows you to exhibit any number of exhibits, which makes the technology attractive for museums with limited exhibition space.

In the modern world, the creation of virtual museums is becoming an important direction in the fields of education, science and culture.

At the invitation of the administration of the Balakhna Museum Historical and Art Complex, RangeVision specialists participated in the preparation of 3D models for their website: it was necessary to perform high-quality 3D scanning of several exhibits with the transfer of color, shape and the smallest details of objects.

All the 3D scanning work took place on the territory of the Balakhna complex. Balakhna is an ancient Russian city founded in 1474 and located on the right bank of the Volga River, 35 km from Nizhny Novgorod. In ancient Russia, this city was the center of industry and was famous for the production of stove and architectural tiles. The tiles were used in the construction of churches, the cladding of houses and the laying of stoves.

The first of the digitized exhibits was the tile of the Church of the Savior (18th century).

The tile consisted of four elements and was carefully moved and installed for scanning. The scan was performed in parts, and after shooting the frame from one angle, the scanner moved. Upon completion of the scan, all the frames were combined and combined into a single 3D model.

The second exhibit, for which a 3D three-dimensional model was made, was a steel helmet from the second half of the 16th century from the Sheremetev collection.

The dark surface of the helmet is decorated with floral ornaments and inscriptions in Arabic. This is a difficult object to 3D scan, because it was necessary to obtain a high-quality surface texture. Since special markers cannot be attached when scanning with textures to simplify the assembly of fragments, the subsequent stitching and merging of scans, as in the first case, was performed manually.

The next digitized exhibits were a badge “Balakhninsky mayor” and an inkwell from the 17th century. They had the same requirements as a helmet.

All the work on scanning the four exhibits took 4 hours, and it took about four more hours to combine the collected data and build models. The finished 3D models were transferred for subsequent posting on the museum's website.

The administration of the Balakhna Museum Historical and Art Complex and the project participants were satisfied with the fruitful cooperation.

Case study: Creating a digital copy of a human using a Calibry 3D scanner.

Briefly: A company called Fora Robotics used a Calibry 3D scanner to create a 3D human model, animate it, and place it in a mobile game.

Task: To develop a pipeline that will allow you to easily create a three-dimensional copy of a person and place it in a mobile or video game.

Tools: Calibry 3D scanner, anthropometric suit, Calibry Nest software and 3D Max software.

The result obtained: A game concept has been created

Fora Robotics used a Calibry 3D scanner to create a digital replica of a human in a mobile game.

The company works in the field of robotics and digital technologies, is engaged in reverse engineering, 3D scanning, creation of custom robots and software. The company's new and ambitious project is to digitize real people and put them in a game where anyone can control their own avatar. The theme of the game with the working title "Fight for Yourself" or simply "FFY" is martial arts. In the near future, Fora Robotics plans to scan professional athletes who practice martial arts and put them in the game. Negotiations are currently underway with one of the national teams to participate in the project.

In the future, anyone will be able to scan themselves to compete with athletes in a mobile game. The user can interact either with characters or with the same avatars. For example, you can digitize a company's team, put all employees in a game, and arrange a competition among digital copies of colleagues. Below we will take a closer look at the process of creating a computer avatar.

1. Create a digital copy using a Calibry 3D scanner. The model was digitized without clothes, as in the future, in the game, the avatar will wear martial arts shorts.

2. The second step is character animation. Creating realistic movements is a rather laborious process. A 3D modeler needs to take into account the features of the anatomy of the created character and correctly distribute gravity so that the movements look natural. At the moment, motion capture technology is popular on the market – using an anthropometric costume, the movements of an actor/model are recorded. Traffic data is recorded in real time.

3. Before putting the model into the game, a small repotology was done in 3D Max. Below are screenshots of the game interface. At the moment, the game is still in the testing stage.

The non-profit organization uses 3D technology to offer affordable prosthetics.

Extending a helping hand…

Case study: A non-profit organization uses 3D technology to offer affordable prosthetics.

In short: the French non-profit organization E-Nable uses Calibry 3D scanners to help children with agenesis get inexpensive prosthetics.

Tasks: there are almost no individual and inexpensive prosthetics for children in France. The goal of E-Nables is to fill this niche.

Tools: Calibry 3D scanner, Calibry Nest software, various 3D printers.

The result is that the cost of prosthetics has been reduced to 50 euros while maintaining the full functionality of the device, made individually for each child.

E-Nable is a non-profit organization in France that uses 3D technology to help children with agenesis (absence or underdevelopment of a body part). According to Mr. Okidam, president and founder of E-Nable France, 3D technologies not only provide children with affordable and customized prosthetics, but also help them feel more confident.

450 children with agenesis are born in France every year. Such families usually have two options:

- Purchase a robotic prosthesis. It provides autonomous movement, but usually such prostheses are expensive, heavy and fragile. They do not always adapt to the morphology of the child's limbs.

- An aesthetic prosthesis. They are easy to find on the market, and insurance companies reimburse expenses for them. These prostheses hide disability, but they can do little to help in everyday life.

E-Nable was created for children with hand or finger agenesis to find an alternative to existing solutions on the market.

Traditionally, specialists use a mold to make prosthetics to order. 3D technologies provide faster results, which is usually comfortable for patients. Prosthetics printed on a 3D printer are not only functional, but also affordable - the cost of one device is 50 euros.

The E-Nable has 3 Calibry scanners in its arsenal. With Calibry, even a person who is far from 3D scanning can easily digitize a forearm, hand, or palm (scanning takes place in geometry mode).

In the next step, the data is processed in Calibry Nest and sent to a 3D printer. At the final stage, the prostheses are decorated in the style of popular cartoons and films, such as "Cold Heart", Superman or Batman, so that every child can become a superhero.

Every year, E-Nable France manufactures more than fifty 3D-printed prosthetics, helping children gain self-confidence.

In short: Hale Dynamics, a company that develops customized workouts for athletes, has used the Calibry 3D scanner to digitize riders for aerodynamic analysis purposes.

The objective is to reduce aerodynamic drag, which, as a result, will lead to an increase in the athlete's efficiency.

Tools: Calibry 3D scanner, OpenFOAM software (open source software for computational fluid dynamics), tape measure, digital angle sensor and levels.

The result is an increase in the rider's speed due to improved aerodynamics.

In top-level sports, every detail is important, and sometimes seconds can determine victory or defeat. Time trial cycling, triathlon, and road racing are disciplines in which aerodynamics determines the rules of the game. Thus, it is very important to optimize the rider's equipment and posture.

This article was written with the support of Hale Dynamics, a company that applies computational fluid dynamics (CFD) to the analysis of cyclists in order to improve their performance.

Aerodynamic drag is the biggest force that slows down an athlete during a race, and the rider himself makes the biggest contribution. It has been estimated that about 80% of the total resistance is created by the athlete. In addition, the aerodynamic drag increases as the speed increases, so the rider has to make more effort to "move through the air."

With the help of 3D technologies and CFD modeling, the rider's efficiency can be increased. In general, such a session can be divided into the following steps::

1. The specialist measures the client's bike with a tape measure, digital protractor and levels. It also photographs the initial position of the rider.

2. It then scans the rider in the starting position using the Calibry 3D scanner.

3. Adjusts the rider's position based on the customer's experience and wishes.

4. Takes measurements and photographs the new position.

5. Scans the rider in a new position.

6. Repeats steps 3, 4, 5 several times. The number of iterations depends on how quickly it is possible to find a preliminary optimal position, as well as on the time and cost of the session.

7. The client leaves with preliminary recommendations.

8. The specialist proceeds to post-process the scans and, if necessary, cleans the geometry. This step is one of the most important, because the quality of the data determines the accuracy of the analysis. At this stage, good geometry and careful cleaning are important.

9. Now the specialist performs an analysis for each scanned pose to obtain the coefficient of resistance (CdA). The simulation is performed in the OpenFOAM program (open source software for computational fluid dynamics) using individual developments.

a) The first step is to create a mesh of the fluid domain. A predominantly hexagonal grid is used, representing a virtual wind tunnel (from the outside of the rider to the tunnel walls). A hexahedral (hexagonal) grid is preferable to a tetrahedral (pyramidal) grid in order to increase the efficiency of the analysis. This step requires good geometry - for example, inverted mesh cells and internal elements can cause problems with the mesh!

b) After constructing the calculation area, an analysis can be performed, which usually takes from 10 minutes to several hours, depending on the required complexity.

10. Finally, the rider is provided with reporting images and a comparative analysis of projected speeds and equipment changes that will help him improve efficiency.

Conclusion:

About 80% of the total aerodynamic drag is created by the athlete. Using 3D technology, Hale Dynamics offers riders an accurate and personalized analysis that allows them to reduce drag and optimize loads.

Replacing the dilapidated Lenin monument with a 3D-printed copy

Replacing the dilapidated Lenin monument with a 3D-printed copy

3D scanning and 3D printing helped create an exact replica of the old concrete monument.

In February 2024, we were contacted by Dmitry Zhamkov's art studio from Balakhna, Nizhny Novgorod region, with which RangeVision has been cooperating for a long time. Together we have implemented projects in the field of culture and museum work, such as scanning cathedral ornaments and helping with the restoration of the Gorky Literary Museum. The new project, which we were happy to participate in, has become both applied and educational.

Dmitry's son, Daniil, who followed in his father's footsteps, has embarked on an ambitious task that requires 3D scanning and 3D printing skills. The task was related to the restoration of the monument to Lenin in the Bolsheboldinsky district.

A dilapidated monument

The original monument to Lenin

Made of sand and concrete, it had become noticeably dilapidated over the past 60 years and was in almost disrepair. The district administration decided to send the monument for a long-term restoration, and at that time replace it with a copy.

The state of the monument in April 2024. It's almost about to collapse.

They decided to make a copy using additive technologies. One of the reasons for this decision was the poor condition of the monument itself: it simply crumbled from almost any touch, its surface was severely damaged, and copying it in this form was not only unproductive, but also dangerous for the original.

A 3D scan of the original monument was also impossible. The project started in the middle of winter, and no 3D scanner could work in the cold. Therefore, a difficult decision was made: to manually recreate the monument, and to "reverse" its already edited large-scale copy.

As a result, the project was planned as follows:

Making a smaller copy of the monument.
Scan a copy of the monument.
Creating a life-size three-dimensional model.
3D printing of the monument.
Installation of a printed copy in place of the original that was used for restoration.

Sculpted repeatedly

The creation of a digital copy of the dilapidated monument turned out to be almost traditional: it was manually "sculpted" in the popular 3D sculpting program ZBrush. It took seven days to create the model.

The monument had to be digitized knee-deep in snow

The resulting model was printed on a printer on a reduced scale and "modified with a file" in the process of meticulous comparison with the original. The result of this work was a plastic replica of the monument that was as accurate as possible in the existing conditions.

Digital and printed model of the monument, requiring additional processing

Now the project team had a physical object in their hands, which was convenient to scan indoors. The scan was required to transfer the improvements to the statue, which it underwent after printing the zebra model.

Scanning training

Before starting work, Daniil Zhamkov needed to master the skills of 3D scanning and model processing. The Neopoint portable 3D scanner was chosen as the working tool for scanning. It is compact, easy to use and at the same time provides good accuracy and detail.

For training, he came to the Nizhny Novgorod office of RangeVision several times, where he learned how to use a scanner, mastered the RV 3D Studio scanning program and practiced on simple objects. The impromptu training course started in early March.

The first lesson on 3D scanning in the Nizhny Novgorod office of RangeVision

Having figured out the basics, Daniel began to practice — and immediately on museum exhibits. As a "dress rehearsal," he scanned a statue of Maxim Gorky from the collection of the Rukavishnikov Estate Museum in the Nizhny Novgorod Museum Reserve.

RangeVision Neopoint is great for digitizing small statues and busts.

The resulting three-dimensional model has completely preserved all the details of the original. The details of the Lenin monument, which was to be copied later, were more modest, so it became obvious that Neopoint could easily cope with this task.

Scan a copy

After completing his studies, Daniil began digitizing a large-scale replica of the Lenin monument.

The optimal scanning mode for such an object is basic

The scanning object is too high and does not fit entirely into the Neopoint scanning area, while it has a diverse and pronounced geometry. Therefore, the turntable and markers were not needed, the statuette was scanned in the basic mode by hand. At the same time, the accuracy of the model's dimensions turned out to be impressive: the deviation of the height in the program from the caliper reading is hundredths of a millimeter.

Impressive accuracy: the dimensions of the three-dimensional and original models match

The resulting polygonal model was then enlarged to the original size of the monument to be printed on a 3D printer.

A monument made of plastic

The Zhamkovs' workshop has several 3D printers with a large work area, as they often print rather large shapes - sculptures, ornaments, and decorative items. The model of the monument was divided into several parts, and each part was printed separately.

The new monument was printed in parts on two printers at the same time

It took 27 working days of pure time to print all the parts of the statue. But since they were printed on two printers at once, the production time was reduced to 14 days. It took another 5 days to solder all the pieces into a single sculpture.

The process of assembling a 3D-printed copy of the monument

Before installation, all seams at the joints were plastered, the finished statue was primed and painted. A replica of the Lenin monument was ready to replace the crumbling original.

The main thing is that the costume fits: the final touches before installing the copy

The plastic monument was installed on the pedestal on May 29, 2024. The original monument was carefully removed and taken away for restoration. Despite the utmost caution of the demolitionists, fragments fell off at the slightest movement from the monument — it was so dilapidated.

The new one is even better

The news about the replacement of the monument on the website of NIA Nizhny Novgorod and in the social networks of the Bolshoy Boldin administration says that the old monument after restoration will be restored in 2025 in concrete or polymer concrete.

According to the head of the Bolsheboldinsky district, the plastic monument looks even more solid and dignified. Maybe we should just leave it that way?

The use of 3D technologies in the creation of sculptures for the Rzhevsky Memorial

The Rzhevsky Memorial to the Soviet Soldier is a grandiose complex created on the initiative of veterans of the Great Patriotic War. The central figure of the composition is the famous 80-ton bronze sculpture of a soldier with a height of 25 meters. Numerous images published in the media captured the painstaking and time-consuming work of the sculptors and engineers involved in the construction of the monument. 3D technologies have also made a contribution, which simplified the preparatory stages, making it possible to avoid a number of serious mistakes.

The scale of a person to a part of a sculptural composition.

The first developments began in 2017, when the commission was presented with sketches of the works. The selection process was long. Only six months later, the sketch by sculptor Andrey Korobtsov and architect Konstantin Fomin was approved. The sculpture of the soldier has been undergoing changes for three years – edits were made by historians and engineers.

The main task was to make a reliable construction – the soil at the site of the monument is swampy and strong winds often blow. Experts had concerns that the frame of the monument might not hold up.

For these purposes, a prototype sculpture (about 2 meters high) was digitized with a Thor3D 3D scanner. We wrote more about this in a 2019 publication. The sculpture was scanned according to the same principle as people are scanned: in a spiral from top to bottom (from the top of the head to the floor). Since the sculpture was large, the scanning session was divided into two parts.: scanning of the head and torso, and scanning of the supporting structure itself. Next, our specialist combined the two parts of the scan into the software and got a ready-made model.

Next, the 3D scan was finalized by ZBrush specialists for a 3D printer and printed in a smaller copy so that it could be "blown" in an air tube.

Then, when all three parts were molded, they were divided into fragments for casting in bronze (there were a total of 600 fragments). The casting was carried out in the workshop of sculptor Alexander Rukavishnikov.

The sculpture was assembled at the site of the future monument and took place in two stages: the assembly of the upper tier and the lower (cranes). The installation started from the head.

On March 31, 2020, work on the creation of the central figure of the memorial was completed.

3D scanning for restoration of the Gorky Literary Museum

3D scanning and 3D modeling helped to restore the lost fragments of the mansion.

In Nizhny Novgorod, for the 150th anniversary of A.M. Gorky, the restoration of the mansion of V. M. Burmistrova, where the Literary Museum named after the writer is located, is being carried out. RangeVision engineers participated in the restoration — they scanned the decorative elements of the historical interior.

The mansion of merchant V. M. Burmistrova is one of the most beautiful architectural monuments of the late 19th century. The building was built in 1882 by N. D. Grigoriev, an architect from St. Petersburg, in the style of academic eclecticism with motifs of Russian Baroque and classicism. After the nationalization of 1918, the mansion served as a historical museum, a dormitory, and a hospital. Despite this, the interiors have been preserved. In the process of their restoration, 3D scanning was applied, a modern approach to the preservation and reproduction of unique specimens. Products made of any materials can be digitized quickly, accurately and safely: wood, stone, metal, porcelain, bone…

RangeVision engineers scanned the dismantled decorative elements in the office and went to the museum to digitize large objects. Beautiful examples of wooden carvings were exposed to the structured illumination of the RangeVision Spectrum optical scanner. 3D models were created using scans and the lost fragments were recovered electronically. In Dmitry Zhamkov’s art workshop, new patterns were carved on a CNC woodworking machine. Imagine how long it would take and how much it would cost to repeat the carving manually.

This method was used to restore the ornament on the entrance oak door of the museum. The scanner operator applied a matting spray so that the glare of the varnish would not affect the shape reading, and pasted several markers to increase accuracy.

Some of the carved parts were removed and digitized at the RangeVision office. The post-processing of the scans was related to the refinement of the geometry, which swam with layers of varnish, and the construction of broken elements.

3D scanning can optimize other restoration processes, such as the restoration of plaster and plastic moldings. It is easier to make molds for casting new parts using 3D scans.

Interestingly, "Small, elegant, like a royal toy…" the Burmistrova mansion and the hostess herself became the prototypes for the novel by I. S. Rukavishnikov "The Cursed Family". It should also be noted that the memorable date of Gorky’s anniversary, March 28, was included in the UNESCO list for 2018−2019.

Quality control of cast parts with RangeVision Standard+

Using the RangeVision Standard+ 3D scanner has helped Dolsatech optimize the quality control process.

Dolsatech, a partner of Iveco and Porsche in Italy, was tasked with more effectively monitoring the quality of cast parts from Chinese suppliers before they were shipped to production. Initially, classic CMMs were used for this purpose, which did not meet the customer’s expectations in some parameters:

speed of operation
inability to capture the entire surface of parts
difficult work with parts of complex shapes.

The company was looking for an easier-to-use system with more throughput for part geometry control and tolerance compliance.

The RangeVision PRO 3D scanner, Standard+ model, operating on the principle of structured illumination, was chosen as the tool for solving this problem. This 3D scanner works with an accuracy of 0.03 mm and a resolution of 0.05 mm and is suitable for working with objects of various shapes and sizes.

Unlike classic CMMs, which are located in specially equipped laboratories where all parts must be transported for inspection, the RangeVision 3D scanner is mobile. By starting to use it, the company was able to scan on its territory, without transporting parts to the laboratory, and reduced its logistics costs. The 3D scanner can be easily placed in both production and warehouse premises. To minimize time costs, the parts are scanned in an optimal location from a logistical point of view. Due to its adaptability, the RangeVision Standard+ 3D scanner allows you to select the optimal scanning area and get a high-quality final 3D model of an object of any size. In this case, a 300×225×225 mm scanning area was used to scan a large part measuring 1.7m x 0.72m.

Before scanning, markers were applied to the part, due to which the stitching of individual scans took place in fully automatic mode, which greatly simplified and accelerated the task. The entire process of creating a 3D model took place in the ScanCenter software included in the RangeVision scanner package.

Rangevision ScanCenter

It took less than 4 hours to fully scan and create a single 3D model of the largest part.

The resulting scan model is transferred by Geomagic for comparison with the original CAD model. It took less than 1 hour to analyze and generate the report.

As a result of comparing the obtained model and the original CAD file, compliance with the tolerances was revealed.

Using RangeVision Standard+, the company was able to reduce the time spent on controlling one part by more than 60%, speed up the process of transferring parts to production and completely eliminate parts from entering the production cycle with non-compliance with tolerances on all surfaces.

Technology: marker scanning, reverse engineering

Location: RangeVision Laboratory

Equipment: RangeVision PRO 2M 3D Scanner

Software: ScanCenter, CAD

Time costs: scanning and processing scans — 4 hours, building models — 8 hours, making drawings — 8 hours

It was necessary to scan three milling cutters from a woodworking machine and make design documentation for their manufacture. Many companies create their own digital archive of consumables in case of wear or operational modernization.

It was especially necessary to accurately reproduce the cutting edge of the tools, so we used a professional RangeVision PRO 2M 3D scanner. To reduce the time required to obtain primary polygonal models, all three cutters were scanned simultaneously. The parts were attached with plasticine to a horizontal surface with pre-glued markers at a minimum distance from each other, avoiding their mutual overlap. Next, we performed a step-by-step circular scan and obtained a faceted surface of objects in the stl format. Mathematical models were created based on the scans.

Since the customer had determined the accuracy criteria for the CAD file in advance, the engineers sent a comparative analysis of the mathematical model with the original scan for approval. This stage is always performed for self-monitoring, but data is provided to the customer upon request. After the verification result was approved, the engineers prepared the drawings.

Now the customer can save on the purchase of fast-wearing tools, minimize dependence on foreign suppliers and plan the production cycle more precisely.

Implementation of the Calibry 3D scanner in the technological process of the orthopedic clinic

Doctors are overloaded! A 3D scanner can help them.

Case study: the introduction of the Calibry 3D scanner into the technological process of an orthopedic clinic to reduce the workload of doctors.

Briefly: A German clinic has asked Phoenix GmbH & Co. to find a solution for automating the production of orthoses in order to minimize the workload of staff. Most of the clinic's patients are children who have to visit doctors frequently as they grow up.

Objective: To develop a standardized and reproducible process that could be used by any orthopedic surgeon without special training in 3D scanning and reverse engineering.

Tools: Calibry 3D scanner, Calibry Nest software, Geomagic Wrap software (with algorithms developed by Phoenix), Tractus 3D printer.

The result: automation of the process has reduced the burden on orthopaedists by 40% in the manufacture of orthoses. In addition, treatment has become more comfortable for patients.

Phoenix GmbH & Co. KG is an engineering company that specializes in the development of products using 3D printing and 3D scanning in the field of sports and orthopedics.

Last year, their client, an orthopedic clinic in Germany, asked Phoenix to develop a technology chain to reduce the burden on doctors, as the standard method of creating orthoses for children was very inefficient.
