The max bed temperature of 0°C is below the recommended 50°C for PLA. Adhesion may be poor without additional bed adhesion aids.
| Filament Nozzle Requirement | 190-220°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 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 PLA specifically, you'll need a printer with a hotend capable of 190°C+ nozzle.
