The HighTemp print sheet is intended for printing with special high-temperature materials, such as PEEK, PEEK-CF, PEI, PEKK, and PPSU, which may otherwise have poor (or too strong) adhesion on standard steel sheets. This sheet is compatible with Prusa Pro HT90.

OVERVIEW:

The Prusa Pro HT90 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets.

Unlike the regular Textured (TXT) sheet, the HighTemp sheet is designed for printing with high-temperature materials. It offers good adhesion to materials like PEEK, PEEK-CF, PEI, PEKK, and PPSU, plus it resists multiple cycles at temperatures over 100 °C. However, this print sheet is not suitable for printing standard low-temperature materials, such as PLA and PETG.

List of supported materials:

PEEK, PEEK-CF, PEEK-GF
PEI1010, PEI 9085, PEI-CF
PEKK, PEKK-CF
PES
PPSU
PSU

This print sheet has a very similar surface structure to the regular TXT sheet. This surface finish is made by powder coating on metal and leaves a nice, distinct textured look on your prints. The textured surface hides most of the mechanical damage caused by tools. Only the tops of the small bumps can be scratched, which will not imprint on the bottom of the model. This type of surface is used on the Prusa print farm. Look at the printed parts you have on your printer for reference.

WARNING

Never clean the HighTemp print sheet with IPA, acetone, or any other alcohol-based solvents! Doing so will damage the surface. Learn more about printing on the HighTemp print sheet in the online Prusa Help article.

Notes:

Consumable parts, such as print sheets (smooth, textured, etc.) are not covered by warranty as the coatings are designed to diminish over time unless failure has occurred due to a defect in materials or workmanship. Cosmetic damage, including but not limited to scratches, dents, cracks, or other cosmetic damage, is also not covered by the warranty. This includes dots caused by probing during the mesh bed leveling process, visible purge line, and local surface damage caused by applying an insufficient amount of Magigoo HT. Only defective sheets on arrival are covered by warranty.
