High Temperature SLA Resin

High-temperature SLA resins are designed for parts that need to stay stiff and dimensionally stable when exposed to elevated heat, in comparison to standard resins that can soften, creep or distort. They’re commonly used for functional prototypes, tooling-style components, jigs/fixtures, airflow parts, and test articles that must hold tight tolerances during thermal or mechanical testing.

In reality the performance of the material depends heavily on post-processing: thorough cleaning, a full UV cure and often a controlled thermal post-cure to achieve the resin’s highest heat resistance. The main trade-off with many high temperature materials is that they tend to be more rigid and less impact-tolerant than “tough” resins, so they’re best when your priority is heat performance, stiffness, and accuracy, rather than flexibility or shock resistance.
