TPU is short for Thermoplastic Polyurethane. It is durable, flexible and strong and is also resistant to abrasion, oil, greases, chemical, and wearing. That’s not all, it’s also resistant to low temperatures so it does not get brittle or warp easily. It has many applications such as cases for electronics, footwear, sporting goods and automotive parts. TPU filament is a medium strength 3D printing material but it can withstand higher compression and tensile forces than its more common counterparts PLA and ABS.
