TPU (thermoplastic polyurethane) is a polymer material that combines rubber elasticity and plastic processability. Its core advantages include:
Wide hardness range (Shore 60A-95A), capable of printing products ranging from soft rubber to semi-rigid plastic.
The elongation at break is as high as 500% -600%, with excellent resilience, suitable for dynamic load scenarios.
Wear resistance far exceeds that of ordinary rubber, suitable for friction components such as gears and tracks.
Resistant to oil and hydrolysis, can be used for a long time in oily or humid environments.
Short term temperature tolerance can reach 80-100 ° C (some modified models support higher temperatures).
It maintains flexibility in low temperature environments (-30 ° C) and is suitable for automobiles or outdoor equipment.
Part of the medical grade TPU has passed ISO 10993 certification and is suitable for medical devices or wearable devices that come into contact with the human body.
Parameter | Recommended Range | Notes |
---|---|---|
Nozzle Temp. | 210-240°C | Low temps cause clogs; high temps increase stringing. |
Bed Temp. | 40-60°C (optional) | Improves first-layer adhesion. |
Print Speed | 20-40 mm/s | High speed may cause layer separation. |
Retraction | 3-5 mm | Critical for reducing stringing. |
Cooling Fan | Off or low speed (<20%) | Prevents poor interlayer bonding. |
