DSM Somos® 9120
Categories:	Polymer; 3D Printing/Additive Manufacturing Polymer
Material Notes:	Product Description: Somos® 9120 is a transparent stereolithography resin that is easy to use and fast to build. This stereolithography resin produces translucent, accurate parts that are semiflexible. Parts produced with Somos® 9120 exhibit excellent water and temperature resistance and mimic polypropylene. Somos® 9120 is ideal for applications such as fluid flow analysis, electrical casings and automotive parts. As this material is semi-flexible, it can also be used for snap-fit functional testing. Key Benefits: Highly transparent Semi-flexible Easy to use and finish Ideal Applications Automotive parts Electrical casings Fluid flow analysis
