One of the problems with modeling vaults, especially with 3D printing, is the many small pieces either don’t print right or get mistaken for other pieces. A new idea is to use fabric infused with the printing process to keep all the pieces intact and grouped together. This may help the modeling a much smother experience and allow for demonstration by quick disassembly and reassembly.
Did some looking into different ways to make molds for resin casting. We used a wood board with 1in pockets drilled into the surface with various materials lining the pockets. We chose, from left to right; scotch tape, aluminum foils in two methods, saran wrap, scotch tape with a bolt, silicone mold condisinor, silicone, plastic cup with a dye test.
I’ve been testing different ways to make molds for resin. Insulation foam doesn’t really work. Resin heats when setting causing the foam to melt.
