TPU (95A) print settings
Rubbery and near-unbreakable. Prints slowly and hates Bowden tubes.
Nozzle 220–235 °C
Bed 30–50 °C
Part cooling 30–60 %
Enclosure Not needed
Drying 50 °C for 6 h
Shrinkage Minimal — too soft to build meaningful internal stress
Density 1.21 g/cm³
Enclosure: Prints fine in open air.
Bed surface & adhesion
Clean PEI holds it well. Skip the glue — removal is already hard enough.
Retraction starting points
Direct drive 0–1 mm
Bowden 0–1 mm
Retraction speed 15–25 mm/s
Flexible filament — minimise retraction and print slowly; a direct-drive extruder is strongly preferred over Bowden.
Good for
