R5 is a liquid photopolymer that produces robust, accurate, and functional parts. 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 R5 exhibit superior fatigue properties, strong memory retention, and high quality up-facing and down-facing surfaces. R5 also offers a good balance of properties between rigidity and functionality.
