PolyFlex™ TPU95-HF

Engineered for High-Speed Performance PolyFlex™ TPU95-HF, developed from Covestro’s Addigy® family, is a thermoplastic polyurethane (TPU) filament designed with high flow properties. This enables significantly faster print speeds compared to standard flexible materials.

Unlocks New Manufacturing Applications With its optimized flow and reliable flexibility, PolyFlex™ TPU95-HF expands the possibilities for using flexible filaments in manufacturing, allowing for rapid production of elastic parts without sacrificing quality.

Ideal for Fast, Flexible Parts Choose PolyFlex™ TPU95-HF when you need to combine flexibility with high-speed production - perfect for rapid prototyping, manufacturing jigs, and functional, elastic components.

Print Tips

This material can be printed on most printers and is designed for high flow. That said, it can print faster on a direct extruder than a Bowden setup.

• The further the gap between your extruder and hotend, the slower you will have to print.

• Print slower if your extruder has a distance between itself and the hotend. 40mm/s - 100mm/s.

• Keep your cooling fan on for good surface quality.

• This material has amazing layer adhesion which will make using parent support material very difficult. It is suggested you design your part to not need support material as much as possible.

• TPU is known for being stringy, so it is going to be difficult to get rid of all of the stringiness/hair on the print.

• TPU95-HF is a slightly harder than 95A and has a shore hardness rating closer to around 98A.

FAQ

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.
