I've been trying to print a mold using some old MakeSolid CastSolid resin (because I have 2 liters of it lying around). The prints come out, but when I try to pour ceramic into the molds, they crack and break apart. Could be old resin. Could be the ceramic mix is getting too hot.
I know the intended purpose is to print the original and throw a mold around it, but we want to print the mold so that we can burn the mold away from the cast part.
Any recommendations about which resins to use?
