3D Scan to Reusable Master Mold

- This project aims to create a mold for mass-producing silicone molds for one of our clients based on the master model they provided. To give us maximum flexibility for scaling and minor shape changes, we decided 3D scanning the piece and 3D printing the master models was the way to go. Here's a high-level workflow containing some lessons learned.
1. 3D Scanning: Spray the piece to be 3D Scanned with a developer spray. We used AESUB 3D Scanning Spray. While the scanning spray may seem expensive, it's not, considering the volume and quality you'll get from the scan. We've tried baby powder, dry shampoo, and even foot spray.
2. Scanning Software Setup: We adjusted the depth camera and unchecked the "Remove Plane" checkbox. We found that we get a better scan by disabling it for thin objects.
3. Point Cloud/Mesh Cleanup: Post-processing was pretty standard using the RevoStudio software. We'll get into those details in another video if you like.
4. Mesh Modeling: A couple of the wingtips didn't capture well, so we did need to repair those spots on the mesh. We expected some minor mesh cleanup due to the thinness of some sections of the model. During cleanup, we asked our Digital Sculptor, Gabriel Andrade, to extrude a flat back to prepare the piece so we could use it as a master model for mold making.
5. Master Model/Mold Box: We went about this mold box differently from usual. We designed a reusable master mold in Fusion 360 and 3D printed it. We need to seal up the 3D print, and we'll be ready to start mass-producing silicone molds. We'll cover that in a future video.
Tools we used (we purchased all of our tools and equipment and are not endorsing any company noted):
CAD (Computer Aided Drafting): Fusion 360 to apply finishing touches to the model and create the reusable master mold.
