Somos® WaterClear Ultra 10122 is a low-viscosity Stereolithography material that produces colorless, accurate parts with excellent temperature resistance. With minimized finishing requirements, parts built in Somos® WaterClear can appear transparent. The material is best suited for applications that require optical clarity, like fluid flow analysis, bottles, lenses, and other concept and functional models. Somos® WaterClear has refractive values like the engineered plastics used in functional testing of optical light transmission work.
