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.

When to use TPU?
TPU's flexibility and durability make it a good material to use in the creation of footwear, elastic soles, protective mobile phone cases, and in automotive parts like tires and shock absorbers.
Pros of TPU
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 of TPU
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.
