The max bed temperature of 0°C is below the recommended 100°C for POM. Adhesion may be poor without additional bed adhesion aids.
| Filament Nozzle Requirement | 200-220°C |
| Printer Max Nozzle | 385°C |
| Filament Bed Requirement | 100-130°C |
| Printer Max Bed | N/A |
What to do instead
- Your printer's bed maxes out at 0°C, but POM needs at least 100°C for reliable adhesion.
- Try a compatible filament for your Markforged FX20 — PLA, PETG, and ABS are good options.
- If you need POM specifically, you'll need a printer with a hotend capable of 200°C+ nozzle and 100°C+ heated bed.
