VC is used extensively for functional prototypes for marketing and consumer trials or as production parts for lower volume.Vacuum casting technique helps in getting a small quantity of plastic pieces with the quality of injection molded components. The method uses cast silicone molds made with the help of a master model created using stereolithography (SLA) typically. Silicone material is cast around the carefully developed master model, partially under vacuum in order to avoid air bubbles being trapped in between the master and silicone. The surface quality and the dimensional accuracy of the master is a determining factor for the quality of vacuum casted components. After curing, the mold is cut according to the parting planes and the master is removed, leaving a cavity to make copies.
