Polymaker PolyFlex™ TPU95-HF 1kg.
PolyFlex™ TPU95-HF, created from Covestro’s Addigy® family, is a TPU with high flow properties making it ideal for high speed printing. Combined with its UV resistance, PolyFlex™ TPU95-HF unlocks new applications for flexible materials in manufacturing.
HF stands for High flow and this flexible filament has a melt index higher than some PLA filaments. This means it can be printed faster than all other flexible filaments and all printing characteristics, such as, retraction and overhangs are improved. Created from Covestro’s Addigy® family, TPU95-HF combines with its UV resistance, flexibility and high-speed printing.

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+.
Printing settings
Nozzle Temperature: 200–220˚C
Bed Temperature: 25˚C-50˚C
Chamber Temperature: 20-30˚C
Printing Speed: 40mm/s-100mm/s
Cooling Fan: ON
Note: Settings are based on 0.4 mm nozzle, and may vary with different printers and nozzle diameters
Bed surface
PolyFlex™ TPU95-HF can be printed on glass, buildtak or similar products, PEI sheet or painters tape. Using Magigoo Pro Flex can improve the adhesion of PolyFlex™ TPU95-HF on the printing surface.
Direct and indirect drive extruders
Direct drive: The extruder is on top of the hot end
Indirect drive: The extruder is linked to the hot end by a Bowden tube
Usually it is recommended to use direct drive printers to print TPU, however the high flow properties of PolyFlex™ TPU95-HF allows the material to achieve high printing speed even on indirect drive printer. (~100mm/s)
Feed rates
Unlike other flexible filaments, the high flow properties of PolyFlex TPU95-HF allows it to have a more consistent extrusion rate, similar to hard materials.
Resistance from the filament spool
PolyFlex™ TPU95-HF has a carefully chosen shore hardness which allows it to not stretch excessively when pulled by the extruder which could results in under extrusion issues. This feature ensures consistent extrusion, even at very high speeds.
Retraction settings
Usually TPU filaments do not handle retraction settings very well because of the flexible nature of the filament. PolyFlex™ TPU95-HF high flow properties means that the filament requires very little pressure change to stop or begin extrusion. Therefore, PolyFlex™ TPU95-HF can handle similar retraction settings as rigid/hard materials.
Dry box system
PolyFlex™ TPU95-HF is a thermoplastic polyurethane (TPU) based material which makes it hygroscopic. This means that it is susceptible to absorbing moisture from the air which can subsequently affect the quality and mechanical properties of the final prints. We recommend storing PolyFlex™ TPU95-HF in a PolyBox™ to prevent moisture absorption. If the filament has absorbed moisture it can be dried at 70˚C for 12 hours in a convection oven.
Support material
PolyDissolve™ S1 is the recommended support material for PolyFlex™ TPU95-HF. PolyFlex™ TPU95-HF is also a great material to support itself.
