Using silicone molds cast over rapid SLA masters, casting is a perfect method for bridging the gap between prototyping and mass production. Simulating the injection molding method, casting is used to produce rigid or flexible parts, opaque or clear, while offering many advantages:
A wide range of urethane or silicone resins are available. In the case of prototyping, urethane resin is selected to reproduce as closely as possible the characteristics of the thermoplastic resin that will ultimately be used in series production. Some meet the UL 94V-0 flammability standard or are FDA compliant. Talk to our technical representatives for the best choice.

Tolerances vary depending on the resin. In general, a tolerance of ± 0.015″ should be expected for the first inch and ± 0.003″ for each additional inch. The geometry of the part and the wall thickness can affect tolerances. It is important to inform us of the critical dimensions to be respected.
