TPU (Thermoplastic polyurethane) is an elastomeric copolymer, made up of alternating soft and hard blocks, which give hardness and flexibility at the same time. This material is ideal for those applications where flexibility and durability are highly desired.
With Shore-A hardness of 98, TPU is a resistant material for several industrial applications, both mechanical or chemical. Moreover, it’s been especially designed to improve the 3D printing experience.
You can purchase TPU from our store: BCN3D TPU

Build plate adhesion:
It is not necessary to use Magigoo when printing that filament, you will get optimal results using a clean printing surface.
Recomendations:
Plastics absorb moisture from the air. For long periods of time without printing, 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.
