Not Compatible
The max bed temperature of 0°C is below the recommended 80°C for PA12-CF. Adhesion may be poor without additional bed adhesion aids.
| Filament Nozzle Requirement | 260-280°C |
| Printer Max Nozzle | 280°C |
| Filament Bed Requirement | 80-100°C |
| Printer Max Bed | N/A |
What to do instead
- Your printer's bed maxes out at 0°C, but PA12-CF needs at least 80°C for reliable adhesion.
- Try a compatible filament for your Markforged Onyx Pro — PLA, PETG, and ABS are good options.
- If you need PA12-CF specifically, you'll need a printer with a hotend capable of 260°C+ nozzle.
