About TPU

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.

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
