How Does 3D Scanning Really Work? – Matt Holling – Ep53

Matt Holling is the engineering manager at Dezignworks. His company specializes in reverse engineering using both laser scanning and bridge CMM. If you don’t know what that is, listen to the podcast, we go over it.

Matt and I have done a lot of work together. While there are many ways to reverse engineer a part, laser scanning is becoming one of the most popular ways and I am often having him do this for me. Once I have the model, I can make edits to the model (add holes, threads, mirror the part, etc).

One major misconception about 3D scanning is that you simply scan a part and instantly have a usable CAD file. The reality is far from this, as the scanner itself only creates a point cloud file. We go over ALL the steps needed to go from the scan, to an STL file, and finally to a fully defined Solidworks file. His company has created a proprietary Solidworks add in to do this work, and the software is impressive (the software also works on Autodesk products).
