SLA Resin liquid photopolymer PP like White Somos® 9120

Short Description:

Material Overview

Somos 9120 is a liquid photopolymer that produces robust, functional and accurate parts using stereolithography machines. The material offers superior chemical resistance and a wide processing latitude. With mechanical properties that mimic many engineering plastics, parts created from Somos 9120 exhibit superior fatigue properties, strong memory retention and high quality up-facing and down-facing surfaces. It also offers a good balance of properties between rigidity and functionality. This material is also useful in creating parts for applications where durability and robustness are critical requirements (e.g., automobile components, electronic housings, medical products, large panels and snap-fit parts).
