E-TruSil

E-TruSil is the first true light curable silicone specifically designed for prototyping via cDLM additive manufacturing. It is a low viscosity yet high performance silicone that upon exposure to light, cures into a tough silicone elastomer.  E-TruSil is available in two variations with Shore A values of 50 and 70, with three colors available in each variation – Clear, White, and Black.  It is intended for use in 3D prototyping where the self-leveling characteristics of speed of cure and low shrinkage are key properties of the application.
