TPU, Thermoplastic PolyUrethane, is an environmentally friendly material with excellent properties of high tension, high tension, strength, toughness, and aging resistance. TPU has been widely used in medical and health, electronic appliances, industry, and Sports, etc. The unique feature is higher elasticity, TPU filament is the most used 3d printing flexible material now.
TPU also has the properties of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, and weather resistance that other plastic materials can not match. at the same time, it has a high waterproof moisture permeability, wind, cold, anti-bacterial, anti-mildew, warm, anti-UV and energy release, and many other excellent functions.
According to molecular structure, TPU could divide into polyester and polyether types. The shore hardness of the filament could range from 60A to 80D.

Frequently Asking Questions
1. What is TPU filament shore hardness?
Our standard type is 95A TPU filament.
2. Do you provide 2.85mm TPU filament?
Yes, we also make 2.85mm TPU filament for the customer. Sometimes, we just have 1.75mm in stock.
3. Is TPU filament food safe?
Tpu is non-toxic and environmentally friendly material. Some types of TPU can be used for medical materials and come into contact with food
4. Do you provide a Tpu filament sample?
Yes, we could provide samples for your testing.
5. How to print TPU filament?
Frankly speaking, TPU filament is not easy to print. You need to search for the best temperature with nozzle and the speed should be much slower.
6. Is the filament UV resistant?
TPU filament does not have anti-UV property. TPU will be yellowing under the influence of UV. Only anti-UV TPU types have anti-UV performance.
7. Is TPU filament stringing?
Due to the high flowability, the filament will be a string in printing. For this problem, you could try with lower temperature.
8. How to set the filament retraction?
Tpu filament is flexible. We do not recommend retraction in setting, if not, the filament is easy to jam in extrusion structure.
