TPU (95A) print settings

Rubbery and near-unbreakable. Prints slowly and hates Bowden tubes.

Nozzle220–235 °C

Bed30–50 °C

Part cooling30–60 %

EnclosureNot needed

Drying50 °C for 6 h

ShrinkageMinimal — too soft to build meaningful internal stress

Density1.21 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 drive0–1 mm

Bowden0–1 mm

Retraction speed15–25 mm/s

Flexible filament — minimise retraction and print slowly; a direct-drive extruder is strongly preferred over Bowden.

Good for

Gaskets, seals, phone cases, tyres, feet and bumpers
Parts that must survive being crushed or bent flat

Watch out for

Print slowly — 15–30 mm/s; faster and the filament buckles instead of feeding
Direct drive strongly preferred; Bowden setups jam at the extruder gear
Retraction near zero — pulling soft filament back just tangles it
