For silicone rubber mold making, any non-porous material is suitable for a master model. This means you could use 3D prints from either filament or resin.Many foundries need a method for making high-precision castings. For a successful change from sand casting to plaster casting, it is necessary for both supervisors and molders to change their work habits and methods. This section will deal with many of these differences in production methods.
