TPU settings for the Prusa MINI+
Possible with tweaks
These are tuned starting settings for printing TPU on the Prusa MINI+. The Prusa MINI+ has a Bowden extruder and an all-metal hotend, 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.

Recommended TPU profile
| Hotend temperature | 225°C (tower 210–235°C) |
| Bed temperature | 50°C |
| Print speed | 20 mm/s |
| Retraction | 3 mm (Bowden) |
| Part cooling fan | 60% |
| Bed adhesion | Sticks well; print slow and disable extra retraction. |
| Nozzle | Brass 0.4 mm is fine |
| Difficulty | Intermediate |
⚠️ TPU is flexible and the Prusa MINI+ uses a Bowden setup, so print very slowly (≤20 mm/s) and reduce retraction to avoid jams.
💡 Best uses for TPU: phone cases, gaskets, wheels.
FAQ
- What temperature should I print TPU on the Prusa MINI+?
- 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 20 mm/s is a safe starting point on the Prusa MINI+. Flexible filament on a Bowden machine must stay slow to avoid filament buckling.
- What retraction should I use?
- Use about 3 mm of retraction (Bowden setups need more). If you see stringing with TPU, raise retraction speed before distance and dry the filament.
- Do I need an enclosure for TPU on the Prusa MINI+?
- No, TPU prints fine in the open on the Prusa MINI+.
