DSM Somos® ProtoTherm™ 12120 Water-resistant resin for stereolithography, UV Postcure
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer

Material Notes: Description: Somos® ProtoTherm 12120 stereolithography material is the perfect solution for applications requiring resistance to heat and humidity. Somos® ProtoTherm 12120 excels at producing highly detailed, extremely accurate parts. The material is dimensionally stable when exposed to heat and humidity making it a good candidate for high temperature fluid flow analysis, functional prototypes, and limited run, non-critical end-use parts such as wiring harnesses and support connectors in electronic devices.

Key Benefits:

  • Extremely Precise Accuracy for Small Details
  • Resistant to Heat up to 250°F (121°C)
  • Stable in High Humidity Environments
Ideal Applications:
  • High-Temperature Fluid Flow Analysis
  • Functional Prototypes Requiring Heat and Humidity Resistance
  • High-Detail Parts
  • Low Volume Connectors and Harnesses for Electronics
