PLA is the most common filament used in consumer 3D printers. Because this is just a quick trial slip casting mold it is practical to print two PLA case molds (lower right) with vertical sides (it is impossible to remove the plaster mold from these without significant damage to the corners. But this is not a problem, PLA filament has a very low melting point so even hot water can soften it - I use a propane torch to heat them (very carefully of course) and they peel off easily. Making these confirms how accurate 3D printers are nowadays - the plaster mold halves mate precisely. Notice there are no natches, they are not needed for prototyping (lining up the outer edges perfectly positions the pieces). And there is no spare, we use a pour spout instead.

Beer Bottle Master Mold via 3D Printing
A project that took several years of failures and blind allies and is finally coming together - so much simpler than expected! |
