DSM Somos® 14120 Water-resistant resin for stereolithography, White  (discontinued **)
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer

Material Notes: DSM Somos® 14120 is a low viscosity liquid photopolymer that produces strong, tough, water-resistant parts. Parts created with Somos® 14120 have a white, opaque appearance similar to production plastics.

Somos® 14120 offers many properties that mimic traditional engineering plastics including ABS and PBT. This makes the material ideal for many applications in the automotive, medical and consumer electronics markets and include:

  • functional prototypes
  • water resistant applications
  • Appearance models with minimal finishing
  • Durable concept models
  • High humidity environment applications
  • RTV patterns
