High Temp Resin is designed for functional prototyping in high heat applications. Understand the technical specifications and best uses.
TIPFor best results, print with Resin Tank LT (Long Term). Standard Resin Tanks may wear more quickly and may print less accurately with this material. Learn more about resin tank compatibility for Formlabs materials.
CAUTIONAvoid storing this material for longer than one month in a standard Resin Tank or two months in a Resin Tank LT to prevent resin leaks and subsequent damage.
The most notable property of this material is its Heat Deflection Temperature, which is the temperature at which a material will deform under a specified load. For High Temp, the heat deflection temperature is 289 °C @ 0.45 MPa.
High Temp is ideal for applications requiring the part to stand up to high temperatures with minimal loading. The material has almost no flex, however, so snap fits and living hinges are not suited for printing with High Temp Resin.

Printing with High Temp
When printing in High Temp Resin with a standard Resin Tank, observe the clarity of the elastic layer and replace the resin tank more often.
High Temp is available in 25, 50, and 100 micron layer heights for both the Form 1+ and the Form 2. Reserve the 25 micron setting only for small objects that are the size of a piece of jewelry or smaller. The only difference between printing at 25 microns and printing at 50 microns is a slightly smoother surface finish. Otherwise, the print quality is the same.
Printing in High Temp Resin requires more laser power. Keep the prints small and move parts around the Build Platform, especially when printing at 25 microns.
Always print High Temp part with supports. Avoid printing parts directly on the Build Platform with High Temp Resin because adhesion issues can occur between the part and the build platform surface. When printing very large or very heavy objects, increase the support touchpoint size or density. If the support touchpoint size is too small, the model may separate from its supports.
The finishing process for parts printed in High Temp varies slightly from the post-print steps for Formlabs Standard Resins. High Temp cannot be rinsed for more than 10 minutes in isopropyl alcohol (IPA), or the part will absorb IPA. If the part is not dried thoroughly it will crack with exposure to light and heat during post-curing. To finish a High Temp part:
- Remove the Build Platform from the machine.
- Remove the part from the Build Platform using the removal tools included in the finishing kit.
- Wash the part for 10 minutes. To automate the washing process, Form Wash agitates the alcohol bath and removes parts from the bath after a set time.
- When using a standard Finish Kit, wash in the first bucket for 5 minutes, then transfer to the second, cleaner bucket for 5 additional minutes.
- Leave the part out to dry.
Use the standard support removal and sanding techniques when post-processing parts printed with High Temp Resin.
Parts printed with High Temp Resin must be washed, dried, and post-cured in order to exhibit the high heat deflection temperature (HDT) and other mechanical properties. Refer to the Form Cure time and temperature settings for post-curing requirements.
