Changed by 28℃ Low Temp.: when the temperature is higher than 28℃, it turns golden yellow automatically. The model will be more gorgeous.

Flexible & SoftTPU (Thermoplastic Polyurethane) is a subclass of thermoplastics which prints strong parts that are also flexible

Durable & Sturdy: Elongation at break ≥800%. It is much higher than other materials, high impact resistance, good flexibility, good tear resistance, wear resistance, and cut resistance, and low long-term compression set.

Strong UV Resistance: Good oil resistance, low temperature resistance and aging resistance. It is suitable for various outdoor scenes.

Easy to print: Compatible with most FDM 3D printers with Direct Extruder and Broden Extruder feeding. Better performance for short-range feeding.


Shore hardness 95A

Printing Speed


  1. It is recommended to dry before printing, (55°C/>4H) to achieve the best It is recommended to use a short-range double-wheel deceleration extruder for flexible design. Generally, eTPU-95A material is difficult to print on a remote extruder.
  2. The remote extruder can try to print at a slower speed. 20mm/s or slower is recommended.
  3. The nozzles may have impurities remaining after a long printing time. It is recommended to use them in conjunction with the cleaning lines. If necessary, new nozzles and throats can be replaced.
