How to print with BCN3D TPU

A material ideal for prints which require flexibility and durability. In this article, you will find the basic information to print with BCN3D TPU





What is TPU?


TPU (Thermoplastic polyurethane) is an elastomeric copolymer made up of alternating soft and hard blocks, which give the material a hardness and flexibility at the same time.

This material is ideal for applications in which flexibility and durability are highly desired.

With a Shore-A hardness rating of 98, TPU is a resistant material for several industrial applications, both mechanical and chemical. Moreover, it’s been specially designed to improve the 3D printing experience.

Build plate adhesion

It is not necessary to use Magigoo when printing this filament, but you will get optimal results using a clean printing surface.


Plastics absorb moisture from the air. When the material is not in use, it is recommended to keep the TPU spools in a box or airtight container with desiccant to keep them dry.

TPU emits low levels of gasses and particles when printed. We recommend printing it in a well-ventilated area to ensure a healthy environment.
