The max bed temperature of 0°C is below the recommended 40°C for TPU. Adhesion may be poor without additional bed adhesion aids.
| Filament Nozzle Requirement | 210-240°C |
| Printer Max Nozzle | 385°C |
| Filament Bed Requirement | 40-60°C |
| Printer Max Bed | N/A |
What to do instead
- Your printer's bed maxes out at 0°C, but TPU needs at least 40°C for reliable adhesion.
- Try a compatible filament for your Markforged FX20 — PLA, PETG, and ABS are good options.
- If you need TPU specifically, you'll need a printer with a hotend capable of 210°C+ nozzle.
