Wat je in plaats daarvan kunt doen

  • Your printer's bed maxes out at 0°C, but PETG needs at least 80°C for reliable adhesion.
  • Try a compatible filament for your Markforged FX20 — PLA, PETG, and ABS are good options.
  • If you need PETG specifically, you'll need a printer with a hotend capable of 230°C+ nozzle.
