PEI / ULTEM Settings for Prusa MK3
Recommended slicer settings for printing PEI / ULTEM on the Prusa MK3 (250 x 210 x 210 mm build volume, 100 mm/s max speed, direct drive extruder).
غير متوافق
The Prusa MK3 has a max nozzle temperature of 300°C, which may be below the minimum recommended 350°C for PEI / ULTEM. Printing may be possible at the lower end of the temperature range but results may be suboptimal. The max bed temperature of 120°C is below the recommended 130°C for PEI / ULTEM. Adhesion may be poor without additional bed adhesion aids.
| Filament Nozzle Requirement | 350-400°C |
| Printer Max Nozzle | 300°C |
| Filament Bed Requirement | 130-160°C |
| Printer Max Bed | 120°C |
ما الذي يجب فعله بدلاً من ذلك
- Your printer's hotend maxes out at 300°C, but PEI / ULTEM needs at least 350°C. No amount of tuning can overcome this hardware limitation.
- Your printer's bed maxes out at 120°C, but PEI / ULTEM needs at least 130°C for reliable adhesion.
- Try a compatible filament for your Prusa MK3 — PLA, PETG, and ABS are good options.
- If you need PEI / ULTEM specifically, you'll need a printer with an all-metal hotend rated for 350°C+ nozzle and 130°C+ heated bed.
