TPU settings for the Creality Ender-3 V2
Creality Print's CR-TPU profile prints at 230 °C, with the bed at 40 °C and the part fan at 100 %.
| Profile | Nozzle | Bed | Part fan | Max flow | Retraction |
|---|---|---|---|---|---|
| CR-TPU | 230 °C | 40 °C | 100 % | 2 mm³/s | 0.4 mm |
How do I set up my file for the Creality Ender-3 V2?
Drop it here. It opens in Convert with the Creality Ender-3 V2 and CR-TPU picked, and nothing converts until you click Convert.
Which build plate should I use?
CR-TPU sets a bed temperature for each plate:
- Textured PEI plate: 40 °C
- Smooth PEI plate: 40 °C
- Cool plate: 35 °C
- Engineering plate: 50 °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). CR-TPU 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 210 °C, the floor CR-TPU declares, since a cooler nozzle strings less (Prusa Knowledge Base). Keep retraction short: CR-TPU retracts 0.4 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.
