Somos PerFORM Material Properties
Behaviour and use
Material Overview
Somos® PerFORM produces strong, stiff, high temperature resistant composite parts that are ideal for tooling and wind tunnel testing applications.
With the lowest viscosity of any composite stereolithography material, parts made from Somos® PerFORM are faster to build, easier to post-process clean, possess superior sidewall quality and provide unmatched detail resolution. It is the ideal material for creating strong, stiff parts with excellent high heat resistance, including wind tunnel models for aerospace and automotive applications, as well as rapid tooling for injection molding.
Key Benefits
- Excellent detail resolution
- Fast, easy processing & finishing
- Superior high heat tolerance
Ideal Applications
- Tooling
- Wind tunnel testing
- High temperature testing
- Electrical casings
- Automotive housings
