Thermoplastic polyurethane (TPU) is an elastomer which has the combination of both thermoplastic and rubber, and is characterized by its high durability and flexibility. TPU scores low on durometers because of its rubber-like characteristic, making it very easy to compress and flex.

Pros
Cons
Pros
TPU filament has high resistance to impact, cuts, weaars, and abrasion. It has also high resistance to oil and grease. It is easier to print compared to TPE, another flexible filament, and is better in keeping its elastic properties even at lower temperatures.
TPU can also withstand ambient temperatures of up to 80°C.
Cons
Due to its good flexibility, TPU is harder to print compared to other filament materials, and is not recommended to be used for small, thin-walled models, or those simulating high elongation materials in terms of SLA manufacturing.
Applications of TPU
The reason why many companies choose Polyethylene as their material in producing mechanical parts and robotics is because it is the perfect filament to combine ductility and strength. Also, it is considered as a great material for ornamental and artistic prints like rings, bracelets, collars, and the like.
