After monitoring 3D scanning technology for more than a decade, we have invested in a new scanner. So here is a small project undertaken to get familiar with the capabilities and solve a real problem – augmenting older designs where CAD is not available – a challenge that some of you may also be facing with legacy equipment.
Classic 1970 Ford Mustang
For my classic 1970 mustang, replacement parts are often not available. However, I could scan the area needed, create new parts, and 3D print replacement designs as a test.
To give you some idea of the accuracy of the scan, below is a scan of my gas tank lid.
Scanning example
The reference dots visible in the image are control dots with a known size used for dimension and automatic range finding. The handheld scanner live-streams to my computer screen to see the real-time results, sweeping it until I get all the data I need. Once I am happy with the scan, I export the STL files and import them to CAD. Finally, everything is fully aligned, and I can print the new part.
It is amazing how these scanners can handle all different materials and surfaces, including painted surfaces, shiny steel surfaces, glass, or films. With the proper technique, you can get fantastic results. It feels like painting where you slowly sweep the surfaces with a laser pattern and watch it fill the computer screen with captured data in real-time. A little too much fun!
Handheld scanner
Like my classic car, it is possible to use the handheld scanner to scan legacy equipment to build retrofit parts. We are heavily investing in this type of technology because we believe that 3D scanners will be a core part of mass customization in past and future factories. Our first application in this regard was done on a legacy system that needed specialized sensor retrofits. The system was scanned. Then we designed and fabricated the necessary retrofit parts and they all fit the first time.
Next up is the scanning of humans for wearable technology fitment.
