Product Description
DSM Somos® 9920 is a liquid photopolymer that produces robust, functional and accurate parts using stereolithography machines. The material offers superior chemical resistance, a wide processing latitude and excellent tolerance to a broad temperature and humidity range during and after build. Parts created from Somos® 9920 exhibit superior fatigue properties, strong memory retention and high quality up-facing and down-facing surfaces. Somos® 9920 also offers a good balance of properties between rigidity and functionality.
