Application history of 3D scanning: solving various tasks in real production facilities
Reverse engineering, geometry control, non-contact measurements, creation of equipment for scientific experiments, virtual museums, product design and other applications of 3D scanners
The 3D scanner helped in the design and manufacture of a custom snorkel, 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 processing the point cloud into a 3D model in Calibry Nest, it was the turn of the solid-state modeling of the hood and windshield parts. The work was done in the Geomagic Design X software.

Next, the task was to design the air intake itself: it had to be designed by analogy with other snorkels, so that the design was working, while repeating the geometry of the body.

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.
