What does the HF stand for?

HF stands for High Flow. This TPU is designed to print fast on direct, geared extrudres and can print even with a Bowden setup.

Can my printer print PolyFlex™ TPU95-HF?

PolyFlex™ TPU95-HF can be printed on an indirect drive printer however we highly recommend to use a direct drive printer to print PolyFlex™ TPU95-HF at its high speed settings. A direct drive printer is a printer with the extruder mounted on top of the hot end.

What makes PolyFlex™ TPU95-HF unique?

PolyFlex™ TPU95-HF is a high flow TPU, which means with the right setup (direct drive printer), it can be printed at 100mm/s+.

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 TPU95-HF 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

Printing Requirements

None! You can print a lot faster if you have your extruder set in a direct fashion and if it has a good gear ratio mechanical advantage - but it is not needed. Just print slower depending on your extruder setup.
