The Prusa Pro HT90 magnetic heatbed is designed to hold a removable double-sided flexible spring-steel sheet, designed specifically for easy removal of printed objects from the print surface.

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. Basic materials such as PLA or PETG do not adhere very well, as this print sheet was developed for high-performance, high-temperature materials.
The HighTemp sheet is made for the Prusa Pro HT90 printer only.
Main attributes
- Compatible with advanced high-temperature materials: PEEK/PEKK, PEI, PPSU
- Great high-temperature resistance: resists multiple cycles at temperatures over 100 °C
- Better wear resistance: better than standard PEI surface
- Textured surface similar to the standard TXT sheet
- Double-sided! Both sides can be used repeatedly
- Easy maintenance and good adhesion qualities
Considerations
Never clean the sheet with IPA, acetone, or any other alcohol-based solvents! This will damage the surface.
For good adhesion properties and easy print removal, clean the print surface with dish soap and water before every printing.
Unsuitable for PLA and PETG. The HighTemp sheet is not suitable for printing with basic materials, as they may not stick too well (or at all).
Keep the sheet as clean as possible! Any grease stain will decrease adhesion.
Not scratch-resistant! Do not use metal spatulas with sharp edges to remove the prints. Be extremely careful when removing the print.
Maintenance
Attracts fingerprints - A good indication of where your sheet is dirty/greasy and that you need to clean it.
Clean with dish soap and water when the sheet is cold. Never clean with IPA, acetone, or any other alcohol-based solvent! It might cause damage to the sheet.
Some types of paper towels may leave traces on the sheet (fiber pieces).
Always use MAGIGOO HT adhesive to ensure optimal adhesion and safe part removal.
Let the prints cool down inside the printer to avoid introducing thermal stress.
Supported filaments

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

Notes
Consumable parts, such as print sheets (smooth, textured, PP, 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.
