Formlabs® High Temp


High Temp Resin

Formlabs' Resin with the Highest Heat Deflection Temperature of 238 °C @ 0.45 MPa

High Temp resin is an ideal stereolithography material for applications that require high thermal stability such as molds and inserts, parts exposed to hot air, gas, and fluid flow, as well as heat-resistant mounts, housings, and fixtures. It is the material with the highest heat deflection temperature (HDT) of 238 °C @ 0.45 MPa in Formlabs' library of liquid photopolymers.

High Temp Resin

For Thermal Stability.

The High Temp Resin, known for offering the highest heat deflection temperature (HDT) among all Formlabs resins, is designed for the creation of detailed and precise parts that require high thermal stability. It boasts an HDT of 238°C under a pressure of 0.45 MPa, alongside enhancements in elongation to reduce brittleness, making it an ideal choice for applications demanding superior heat resistance.

Testing prototype parts exposed to high temperatures can be difficult, as many prototyping materials tend to deform under heat. To reduce costs and speed up iteration at every product testing phase, opt for 3D printing fully dense, watertight parts. These parts have low absorption and can withstand direct contact with hot liquids or steam, making them ideal for functional testing in high-heat scenarios.

A Material with Almost No Flex

High Temp Resin is ideal for applications requiring parts to endure high temperatures with minimal deformation. However, this material lacks flexibility, making it unsuitable for creating snap fits and living hinges.

Cost-Efficient Rubber Molds For Production Casting

Optimize your rubber molding process by utilizing 3D printing technology to create precise master patterns. This approach not only accelerates the development cycle but also significantly cuts down manufacturing expenses. Leverage these master patterns to fabricate molds capable of mass-producing wax models for the investment casting technique.

For projects requiring cold molding (RTV), Standard Resins are the ideal choice, offering reliability and quality. Meanwhile, for applications demanding exposure to high temperatures, such as vulcanizing natural rubber, opt for High Temp Resin for its exceptional heat resistance. This method streamlines the production workflow, ensuring efficient and cost-effective production of rubber components.

Prototype Packaging with Vacuum Forming & 3D-Printed Molds

Vacuum forming is a widely used manufacturing method for creating lightweight, cost-effective packaging for various goods, including grocery store items, coffee cup lids, and high-end consumer electronics. The vacuum-forming process involves four basic components: a mold or tool that will create the shape of the final part, a sheet of plastic, a heat source, and a vacuum source.

Opt for vacuum-forming molds rather than traditional processes such as machining, which can be quite costly and time-consuming, especially for complex geometries, textured surfaces, or fine features.

Post Processing



6 minutes


High Temp Resin should not be left in solvent for more than 6 minutes, as prolonged exposure significantly affects the quality of the final part.

form wash and form cure form wash and form cure



120 minutes


80 °C

To achieve the highest HDT of 238°C @ 0.45 MPa:

1. Post-cure parts in Form Cure for 120 minutes at 80°C.
2. Thermally post-cure parts in a non-food oven for 3 hours at 160°C.
For applications not requiring maximum heat resistance, post-cure parts in Form Cure for 60 minutes at 60°C.
