TPU
TPU brings elasticity and impact absorption. Direct drive makes life easier; tune retraction and speed to prevent jams.
Typical print: Nozzle 215–235 °C, Bed 40–60 °C, 20–35 mm/s
Drying: 45–50 °C for 6–8h if stringing.
Adhesion: PEI or glass with light glue stick.
Notes: Ventilate as normal; avoid overheating.
Pros
- Flexible & tough
- Great grip
- Fun functional prints
Cons
- Slow prints
- Path sensitivity on Bowden
- Stringing if wet/too hot
Extruder Setup
Direct-drive preferred. On Bowden, shorten tube and reduce retraction.
