SLA – High Temp Resin
High Temp Resin is a type of 3D printable material specifically designed to withstand high temperatures without deforming or losing structural integrity. It is commonly used in applications that require thermal resistance and dimensional stability under heat stress.
Key Material Facts:
- High Temp Resin offers a heat deflection temperature (HDT) of 238 °C @ 0.45 MPa, the highest among SLA resins.
- Use it to print detailed, precise prototypes with high temperature resistance.
- High Detail for demanding applications, capture the finest of features
- Parts can be printed solid and air / fluid tight right off the printer, no sealing required
- Compatible with assembly features including:
- Glue Joints / light welding
- Printed In Threads (However Helicoils are recommended)
Common Applications:
- Heat resistant mounts, housings and fixtures
- Hot air, gas and fluid flow visualizations
- Low quantity production of small parts
- Molds and inserts
- Semi transparent parts
- Medium temperature vulcanized rubber molding
