PEEK Settings for UltiMaker S3
Recommended slicer settings for printing PEEK on the UltiMaker S3 (230 x 190 x 200 mm build volume, 300 mm/s max speed, direct drive extruder).
Not Compatible
The UltiMaker S3 has a max nozzle temperature of 280°C, which may be below the minimum recommended 370°C for PEEK. Printing may be possible at the lower end of the temperature range but results may be suboptimal. The max bed temperature of 85°C is below the recommended 130°C for PEEK. Adhesion may be poor without additional bed adhesion aids.
| Filament Nozzle Requirement | 370-420°C |
| Printer Max Nozzle | 280°C |
| Filament Bed Requirement | 130-160°C |
| Printer Max Bed | 85°C |
What to do instead
- Your printer's hotend maxes out at 280°C, but PEEK needs at least 370°C. No amount of tuning can overcome this hardware limitation.
- Your printer's bed maxes out at 85°C, but PEEK needs at least 130°C for reliable adhesion.
- Try a compatible filament for your UltiMaker S3 — PLA, PETG, and ABS are good options.
- If you need PEEK specifically, you'll need a printer with an all-metal hotend rated for 370°C+ nozzle and 130°C+ heated bed.
