When you need multiple parts, or when the materials and finishes that printed models can provide just don’t meet your requirements, molding and casting is another option.
RTV (Room Temperature Vulcanizing) Rubber can be used to mold your parts and make exact replicas.
Castings can be made in the materials you want, to do all the things that your prototype is meant to do.
A single rubber mold produces an average of 10-15 castings, depending greatly on the complexity of the parts and the materials used. Multiple molds can be used for short-run production.
This particular mold will produce over 20 castings.
