I’m glad to see this work flow (engraved-casting) comes out pretty decent.
I do a lot of casting (car reproduction badges and stuff) and was wondering how well casting engraved stuff would work. Good to see that it comes out pretty decent with respect to surface finish, especially with how well silicone picks up every line. So many ideas here.
I’ve also had a lot of success with embedding fiberglass cloth or very thin metal wire in the resin to improve bulk object strength (e.g., the crack in the earlier casting), also cuts down on resin usage.
Have you thought to try any of the low-melt metals yet?
