TPU print settings

Flexible, rubber-like filament for gaskets, phone cases, and dampers. Sold by Shore hardness (95A is firm-flexible, 85–90A is softer). Prints slow and best on a direct-drive extruder; Bowden setups struggle. Moisture-sensitive. Patience over speed is the rule.

Starting points, not gospel. TPU settings vary by brand, printer and slicer — run a temperature tower on each new spool. Every per-brand number below is the manufacturer's own published recommendation, with its source grade and the date checked.

What TPU is good (and bad) for

Good for

Gaskets, seals, vibration dampers
Phone cases and grips
Flexible hinges and bumpers
Wearables

Avoid for

High-speed printing
Bowden extruders (soft grades especially)
Sharp detail and tall thin features

Drying & storage

TPU is quite hygroscopic; wet TPU bubbles and strings. Dry 65–70 °C for 6–8 h and print soon after, ideally from a dry box.

Bed adhesion

Adheres to PEI/glass at a low/no bed temp. The real requirement is mechanical: a direct-drive extruder and slow, steady flow to avoid jams.

Heat resistance

Varies by grade; generally modest. Chosen for flexibility, not heat resistance.

TPU FAQ

What temperature do you print TPU at?

Across the 2 TPU filaments in this database, manufacturers recommend nozzle temperatures of 210–230 °C and bed temperatures of 25–60 °C. Exact values are per-brand (see the table); always run a temperature tower on a new spool.

Does TPU need an enclosure?

No. TPU prints fine without an enclosure.

How do you dry TPU?

TPU is quite hygroscopic; wet TPU bubbles and strings. Dry 65–70 °C for 6–8 h and print soon after, ideally from a dry box.

How heat-resistant is TPU?

Varies by grade; generally modest. Chosen for flexibility, not heat resistance.
