Somos® ProtoTherm™ 12120

Somos® ProtoTherm™ 12120 for Heat-Resistant Functional Parts

Technical Overview

Somos® ProtoTherm™ 12120 is a stereolithography (SLA) photopolymer specifically formulated for applications where high temperature resistance and accuracy are essential. This material produces rigid, dimensionally stable components with an specified surface finish directly from the printer. Its key differentiator is the combination of thermal performance and the ability to produce highly detailed, precise parts, making it a reliable solution for challenging industrial environments.

Performance: Thermal and Mechanical Stability

Engineered to perform under thermal stress, this material maintains its structural integrity and mechanical properties at elevated temperatures up to 121°C (250°F). Its defined composition ensures parts are strong and durable enough for functional testing. Furthermore, ProtoTherm 12120 demonstrates excellent stability in high-humidity environments, preventing deformation and ensuring reliable performance over time.

Performance: Surface Quality and Precision

A standout feature of this material is the professional-grade surface quality it achieves without extensive post-processing. This smooth finish reduces the need for manual sanding or finishing, accelerating the production workflow. The material also excels at capturing fine details and intricate geometries with extreme accuracy, making it ideal for complex components like electronic connectors and detailed prototypes.

Design and Processing

Somos® ProtoTherm™ 12120 is designed for use on 355 nm stereolithography systems. As with standard SLA resins, parts require post-processing, including cleaning and a final UV post-cure, to achieve their optimal mechanical and thermal properties. Its stability in humid conditions simplifies handling and storage requirements.

Lifecycle: From Functional Prototype to Production

This material is positioned to support demanding product development cycles. It is an excellent choice for creating high-fidelity functional prototypes for performance testing in heated or humid conditions, such as fluid flow analysis. It is also suitable for producing limited-run, non-critical end-use parts, custom tooling, and manufacturing aids where thermal and dimensional stability are critical.
