¶ 1. Preparation
Due to the high feeding resistance of the PTFE tube in the Ender-5 Max, printing TPU from the printer's built-in spool holder may result in empty extrusion and insufficient extrusion.
Therefore, the following steps are necessary when printing TPU:
Note: This method cannot use the Filament Detector Kit Function. You can insert a short piece of filament into the Filament Detector Kit or choose to ignore the Filament Detector Kit when printing.
- Open the upper cover of the printer and feed from the top of the machine, not through the printer's PTFE tube. The filament spool should be higher than the printer.
- Fix the original PTFE tube of the printer to prevent it from scratching the model during printing.
- Since TPU easily gets moisture, please use newly opened filament or dry it before use. Otherwise, defects such as printing stringiness and poor surface quality may occur.
- Choose TPU with a hardness of 95A or above, such as the common TPU95A/TPU64D.
¶ 2. Slicing
- Select GenericTPU or CR-TPU filament in the slicer.
- If using a third-party software, manually adjust the printing speed to below 50mm/s.
- If the surface quality is poor, you can manually lower the printing temperature to 205-215°C.
