The max bed temperature of 0°C is below the recommended 80°C for Glass-fiber PETG. Adhesion may be poor without additional bed adhesion aids.
| Filament Nozzle Requirement | 235-260°C |
| Printer Max Nozzle | 300°C |
| Filament Bed Requirement | 80-95°C |
| Printer Max Bed | N/A |
What to do instead
- Your printer's bed maxes out at 0°C, but Glass-fiber PETG needs at least 80°C for reliable adhesion.
- Try a compatible filament for your Markforged FX10 — PLA, PETG, and ABS are good options.
- If you need Glass-fiber PETG specifically, you'll need a printer with a hotend capable of 235°C+ nozzle.
