DSM Somos® Momentum Stereolithography Polymer
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer

Material Notes: DSM collaborated with key footwear manufacturers to develop an additive manufacturing material that addresses the specific needs for footwear tooling. Somos® Momentum offers high part accuracy, quality and fine feature detail. The accuracy of the resin allows the forming of sharp features which in turn enables the creation of detailed soles not only in initial design, but also translated into the aluminum mold.

Properties reported after UV postcure.
