| Filament Nozzle Requirement | 195-220°C |
| Printer Max Nozzle | 385°C |
| Filament Bed Requirement | 50-60°C |
| Printer Max Bed | N/A |
What to do instead
- Your printer's bed maxes out at 0°C, but Copper-fill PLA needs at least 50°C for reliable adhesion.
- Try a compatible filament for your Markforged FX20 — PLA, PETG, and ABS are good options.
- If you need Copper-fill PLA specifically, you'll need a printer with a hotend capable of 195°C+ nozzle.
