Can my printer print PolyFlex™ TPU90?

We highly recommend to use a direct drive printer to print PolyFlex™ TPU90. A direct drive printer is a printer with the extruder mounted on top of the hot end.

What makes PolyFlex™ TPU90 unique?

PolyFlex™ TPU90 is easier to print than similar flexible material thank to its high melt index.

What does the number stand for?

The number next to "TPU" refers to the shore hardness. A higher number means a harder material. TPU90 is our softest, followed by TPU95 and then TPU95-HF (which is closer to a shore hardness of 98A than 95A).

In 3D printing the shore hardness is only an indication on how flexible the printed part will be. However it is important to also take in consideration the infill percentage, number of walls, top/bottom layers and the layer height.

Do you have any suggestions when printing TPU90 with support structure on single extruder printer?

Generally, when printing with TPU materials, if support structures are needed, we recommend using specialized support materials such as PolyDissolve™ S1. However, considering the single extruder devices that users may have, we suggest customers adjust the orientation of the model to minimize the use of support structures, or place support structures in inconspicuous areas that won't affect the appearance.
