The Creality Ender 3 S1 Pro has a max nozzle temperature of 300°C, which may be below the minimum recommended 350°C for PEI / ULTEM. Printing may be possible at the lower end of the temperature range but results may be suboptimal. The max bed temperature of 110°C is below the recommended 130°C for PEI / ULTEM. Adhesion may be poor without additional bed adhesion aids.

מה לעשות במקום

  • Your printer's hotend maxes out at 300°C, but PEI / ULTEM needs at least 350°C. No amount of tuning can overcome this hardware limitation.
  • Your printer's bed maxes out at 110°C, but PEI / ULTEM needs at least 130°C for reliable adhesion.
  • Try a compatible filament for your Creality Ender 3 S1 Pro — PLA, PETG, and ABS are good options.
  • If you need PEI / ULTEM specifically, you'll need a printer with an all-metal hotend rated for 350°C+ nozzle and 130°C+ heated bed.
