Derivatives & Variations
TPU has various variations based on hardness.
TPU 85A
Standard hardness. Balanced flexibility and printability.
TPU 95A
Slightly harder. Easier to print with good mechanical strength.
TPU 70A
Very flexible. Rubber-like texture, high print difficulty.
TPU-CF
Carbon fiber reinforced. Maintains flexibility with improved strength.
Use Cases
Suitable Applications
- • Phone cases
- • Gaskets & seals
- • Shoe soles & insoles
- • Vibration damping & cushioning
Pros & Cons
Pros: Flexibility, wear resistance, elasticity
Cons: Difficult to print, slow speed, stringing
Precautions
• Direct drive extruder printing is strongly recommended.
• Set print speed to slow 15-30mm/s.
• Minimize retraction settings to prevent stringing.
