DSM Somos (Elgin, Ill.), a developer of stereolithography resins for rapid prototyping, has announced commercialization of NanoTool, the third generation of Somos ProtoComposite materials. Heavily filled with noncrystalline nanoparticles, the material reportedly enables faster processing, reduces finishing requirements and has a flexural modulus of 10,500 MPa/1,523 ksi, a heat deflection temperature of 260°C/500°F (at 0.46 MPa/0.07 ksi after thermal post-cure) and linear shrinkage of less than 0.001 inch/0.03 mm. The material’s smooth surface quality and high initial modulus also make it suitable for metal plating as an alternative to fully metal prototypes.
