DSM Somos® 9420 Epoxy Resin for Stereolithography
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer; Thermoset; Epoxy

Material Notes: Description

Somos® 9420 is an opaque white stereolithography resin that is easy to use and fast to process. This stereolithography resin produces accurate parts that are semiflexible. Parts produced with Somos® 9420 are comparable to polypropylene in mechanical properties and offer a good combination of flexibility and toughness. Somos® 9420 is ideal for applications such as the design and testing of snap-fits, electronic and automobile components as well as packaging.

Key Benefits:

  • Flexible
  • Incredible Memory Retention
  • Tough & Durable
  • Bright Opaque-White Color
Ideal Applications:
  • Prototypes where polypropylene will be the final production plastic
  • Packaging design
  • Snap fits, bottle tops, fittings
