Stereolithography. This is a technology for making articles from materials that polymerize in the result of chemical reactions or have low hardening temperatures.
The advantage of this technology is simplicity and short production period of casting accessories from two-component silicones. Silicone composite precisely reproduces dimensions and surface texture of master-model, had low adhesion susceptibility and its elasticity allows in several cases to solve the problem of articles’ undercuts quite easily. Using one silicone form one can make up to 20-50 casts.
