TPU settings for the Creality K2 Plus
Creality Print's Generic TPU 64D profile prints at 220 °C, with the bed at 40 °C and the part fan at 100 %.
| Profile | Nozzle | Bed | Part fan | Max flow | Retraction |
|---|---|---|---|---|---|
| Generic TPU 64D | 220 °C | 40 °C | 100 % | 2 mm³/s | 2 mm |
| CR-TPU | 220 °C | 40 °C | 100 % | 2 mm³/s | 1.2 mm |
| Generic TPU | 220 °C | 40 °C | 100 % | 2 mm³/s | 2 mm |
| HP-TPU | 220 °C | 40 °C | 100 % | 3 mm³/s | 1.2 mm |
| eSUN TPU-95A | 230 °C | 35 °C | 100 % | 2 mm³/s | 2 mm |
How do I set up my file for the Creality K2 Plus?
Drop it here. It opens in Convert with the Creality K2 Plus and Generic TPU 64D picked, and nothing converts until you click Convert.
Which build plate should I use?
Generic TPU 64D sets a bed temperature for each plate:
- Textured PEI plate: 40 °C
- Smooth PEI plate: 40 °C
- Cool plate: 40 °C
- Engineering plate: 35 °C
How fast can I print TPU?
Prusa suggests about 20 mm/s for flexible filament and at most 30 to 40 mm/s, or it can clog the nozzle or tangle in the gears (Prusa Knowledge Base). Generic TPU 64D caps flow at 2 mm³/s, and the slicer slows any move that would push more (slicer source).
Why is my TPU stringing?
Lower the nozzle toward 215 °C, the floor Generic TPU 64D declares, since a cooler nozzle strings less (Prusa Knowledge Base). Keep retraction short: Generic TPU 64D retracts 2 mm, and longer retraction can clog the nozzle (Prusa Knowledge Base).
Do I need to dry TPU?
Yes, Bambu Lab marks drying as required for TPU, at 70 °C for 8 hours in a forced-air oven (Bambu Lab wiki). Wet flexible filament is hard to print (Prusa Knowledge Base).
Where do these values come from?
From the profiles Creality Print ships, read at CrealityPrint v7.3.1 (254250c). Where a filament profile leaves retraction unset, the table shows the printer profile's value.
