Thermoplastic polyurethane (TPU) belongs to a class of polyurethane plastics having many important properties such as elasticity, transparency, and resistance to grease, oil, and abrasion. It is unique due to its extremely flexible nature. Technically speaking, TPUs are made up of thermoplastic elastomers.
TPU has different advantages such as resistance to abrasion, ability to perform at low temperature, elasticity, and mechanical properties along with rubber-like elasticity.
TPU printing filament is flexible in nature. It can bend easily without any effect on the design, strength and durability. A mild soap can be used for its cleaning.
Flexible TPU filaments can be stored in a cool airtight container. Container may also have a desiccant pack, so that filament remains bone dry. This container can also help in preventing the entry of dirt and dust particles, so that the filament could be used anytime for print. Although some type of TPUs are water-resistant, prolonged contact with water could result in degradation of the product.
For optimal results print flexible TPU filaments on direct extruders; however, it is possible to print on Bowden extruders as well. Flexible TPU filaments have the ability to adhere well to most surfaces such as glass, aluminum, Kapton tape, and blue painters tape. It is important to always print in a well ventilated room regardless of the filament type.
