¶ 1. Preparation
Due to the large feeding resistance of Teflon tubes in K series machines, printing TPU from the machine’s built-in filament rack will cause empty printing and insufficient extrusion.
So printing TPU requires the following work:
Note: This method cannot use the Filament Detector Kit Function. You can cut a piece of filament and insert it in the Filament Detector Kit, or choose to ignore the Filament Detector Kit when printing.
-
Open the upper cover of the machine and feed from the top of the machine. Do not feed from the Teflon tube of the machine. The filament rack is higher than the machine.
-
Fix the original Teflon tube of the machine to prevent the model from being scratched during printing.
-
TPU easily gets moisture, so please use freshly opened filaments or dry them 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. Creality Print
-
Select GenericTPU or CR-TPU filament in Creatlity Print
-
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℃
