PolyFlex™ TPU95
PolyFlex™ TPU95 is a thermoplastic polyurethane (TPU) based filament specifically engineered to work on most desktop 3D printers. It has a shore hardness of 95A and can stretch more than 3 times its original length.

Print Tips
This material can be printed on most printers, but 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 slow, and even slower if your extruder has a distance between itself and the hotend. 30mm/s - 60mm/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.
95 refers to it's shore hardness of 95A.
FAQ
Can my printer print PolyFlex™ TPU95?
We highly recommend to use a direct drive printer to print PolyFlex™ TPU95. A direct drive printer is a printer with the extruder mounted on top of the hot end.
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 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.
