| Filament Nozzle Requirement | 240-270°C |
| Printer Max Nozzle | 385°C |
| Filament Bed Requirement | 75-90°C |
| Printer Max Bed | N/A |
What to do instead
- Your printer's bed maxes out at 0°C, but CPE needs at least 75°C for reliable adhesion.
- Try a compatible filament for your Markforged FX20 — PLA, PETG, and ABS are good options.
- If you need CPE specifically, you'll need a printer with a hotend capable of 240°C+ nozzle.
