Que faire à la place

  • Your printer's bed maxes out at 0°C, but PEEK needs at least 130°C for reliable adhesion.
  • Try a compatible filament for your Markforged FX20 — PLA, PETG, and ABS are good options.
  • If you need PEEK specifically, you'll need a printer with an all-metal hotend rated for 370°C+ nozzle and 130°C+ heated bed.
