3D Technology in automotive industry

Recently, one of our partners, Terem3D reached out, suggesting a project: use 3D technologies to reverse engineer a hard-to-replace car part.

The company wanted to reconstruct a sub-flap bar after a car accident with the help of Drake 3D scanner and reproduce it on the BigRep 3D printer. The bar was relatively small (45 x 5 cm), had a curvature along all axes and had a broken lug. It would be difficult to measure it using conventional tools, so the Drake scanner was used.

The step by step:

The job itself took a few minutes. We added some crumpled paper around the object to add “geometry” and help with for tracking during scanning.

After scanning was done, Terem3D post-processed the scans in the Netfabb software. At this stage the broken lug was repaired.

After post-processing, the bar was successfully printed on the BigRep 3D printer ready to be used:

The car was ready to go!
