What is TPU filament?
TPU stands for thermoplastic polyurethane. This filament falls under the flexible filaments which are also called TPE (thermoplastic elastomer). There are different types of TPE, with thermoplastic polyurethane (TPU) being the most commonly used among the 3D printer filaments. As the name suggests, this material is elastic in nature so that the plastic can easily be stretched and bent. TPU is the easiest to print from the flexible materials.
The material can best be described as the golden mean between hard plastic and silicone. It combines the good properties of both materials, which ensures that TPU is flexible, yet form-retaining, can not break, attracts dust and hardly scratches. The material can also be completely transparent.
We call the TPU filament jokingly “pulldddrop”. It will not surprise you that TPU is used for flexible and flexible applications. TPU is widely used for rubbery solutions, because rubber itself can not be printed. TPU is for example used in the shoe industry, but also for pads and other shock absorbing applications.
