Join us on our four week journey of taking a sports car lens for which there were no CAD files or prints through reverse engineering to develop CAD, the design and creation of a tool, part production and finishing.

SHAPEMASTER’S COURSE OF ACTION:
3D Scan for Creation of Lens Covers
PROCEDURES FOR SCANNING AND 3D MODEL CREATION:
After parts were evaluated for the scanning process, it was determined that due to the amount of undercuts, a reverse clay model was needed. After the clay model was finished, it was then painted a flat white and red registration marks were applied for the scanning process.
This model was then placed in position so that the scanner could pick up the proper detail needed. The model was re-positioned many times to take multiple scanning “shots”. All of these shots were then recorded in the scanning
After all scanning “shots” were taken, the scanning software was used to align the red registration marks to create a complete scanned project.
3D MODEL CREATION:
Once the scanned object has all of the scanned “shots” aligned it is then stitched together to form a triangled mesh. This mesh looked like the part that is needed but it is not a useable model for manufacturing. A conversion process was needed that employs some different software.
The conversion to a solid model began by stitching all scanned “shots” into one object. We then implemented specialized software in the conversion process. These steps were used for both sizes of parts to be modeled. This software then created either a series of surfaces or a solid model that was then used in the design of the tooling for the manufacturing of the part.
Once the Solid Model had been produced, a 3D model or prints of the design could be made for customer approval and or development of tooling for the production of the parts.
This was quite a journey indeed. Make sure to follow us next week for designing the tool.
