TPU flexible 3D printing
TPU is a rubber-like, flexible yet wear-resistant plastic. Use it for seals, grips, dampers and protective parts that must stay elastic.
Material properties
| Tensile strength | ~25–40 MPa |
|---|---|
| Heat resistance | ~60–80 °C |
| Toughness | very high (flexible) |
| Key property | flexible, wear resistant |
Values are indicative; they vary with print orientation and settings.
Why choose it?
- Rubber-like elasticity, high elongation
- Excellent wear and impact resistance
- Vibration-damping effect
- ~60–80 °C heat resistance
Typical applications
- Seals, rings, grommets
- Grips, feet, bump stops
- Dampers, protective covers
- Flexible connectors, hose joints
Keep in mind
- Fine thin details are softer and less crisp
- Not for very stiff structural parts — use PA12 or PA12-CF
