Higher Heat Deflection Temperature SLA Resin Bluish-black Somos® Taurus

Short Description:

Material Overview

Somos Taurus is the latest addition to the high impact family of stereolithography (SLA) materials. Parts printed with this material are easy to cleaned and finished. The higher heat deflection temperature of this material increases the number of applications for the part producer and user. Somos® Taurus brings the combination of thermal and mechanical performance that until now has only been achieved using thermoplastic 3D printing techniques such as FDM and SLS.

With Somos Taurus, you can create large, accurate parts with excellent surface quality and isotropic mechanical properties. Its robustness combined with a charcoal grey appearance makes it ideal for the most demanding functional prototyping and even end-use applications.
