TPU settings for the Creality K1
Great match
These are tuned starting settings for printing TPU on the Creality K1. The Creality K1 has a direct-drive extruder and an all-metal hotend in an enclosed chamber, so we set the hotend to 225°C and the bed to 50°C. TPU is flexible and prints best slow with a direct-drive extruder; Bowden setups must go very slow.

FAQ
- What temperature should I print TPU on the Creality K1?
- Start at 225°C for the hotend and 50°C for the bed, then run a temperature tower across 210–235°C to dial in your exact filament brand.
- What print speed works for TPU on this printer?
- Around 25 mm/s is a safe starting point on the Creality K1. This printer can go faster once the profile is tuned, but start conservative for clean walls.
- What retraction should I use?
- Use about 1 mm of retraction (direct drive needs very little). If you see stringing with TPU, raise retraction speed before distance and dry the filament.
- Do I need an enclosure for TPU on the Creality K1?
- No, TPU prints fine in the open on the Creality K1.
