About Urethane Castings

Urethane casting (or polyurethane casting) is ideal for additive manufacturing short-run production of pieces made from a plastic injection molded resin. Often performed after an RTV mold (also called a room temperature vulcanization mold) is made from a stereolithography (SLA) prototype, urethane casting is a cost-effective way to reproduce production-ready parts in small quantities.

After a mold is created, urethane casting material – synonymous with polyurethane casting material – is injected into the mold’s “void.” This allows for near-perfect copies of the original prototype to be created. We have low durometer urethanes that can be very soft, but we can also make stereolithography molds and inject silicone rubber into it.

Urethane casting provides:

Typical Casting Use Cases

Small-batch manufacturing Engineering design verification Alpha and beta builds
Pre-production parts
