question about lost pla casting - often i will use red filler primer or heavy scratch primer to get rid of the print lines and make a smooth looking 3d print.
will that stuff burn out with the pla in my mold or will it leave a shell like a sheetrock mud coat might do ? thought about just plain parifin wax and painting it on the outside however i have warped pla prints with hot wax before so wanted to use the primer if it will burn out.
want to use plaster as the mold material, burn out the pla and hopefully the primer as well.
