Flexible :  PolyFlex TPU-95A-HF, created from Covestros AddigyÆ family, is a TPU with high flow properties making it ideal for high speed printing. Combined with its UV resistance, PolyFlex TPU-95A-HF unlocks new applications for flexible materials in manufacturing.



 

Printing settings

  • Nozzle Temperature: 200220C
  • Bed Temperature: 25C-50C
  • Chamber Temperature: C 20C-30C
  • Printing Speed: 40mm/s-100mm/s
  • Cooling Fan: ON

PolyFlex TPU-95A-HF is a TPU specifically engineered to have high flow and UV resistance properties:

High Flow property:

To extrude a material the extruder has to push the filament towards the nozzle in order to create a certain degree of pressure to overcome the materials viscosity. The viscosity of the material mainly depends on the nozzle temperature. The higher the temperature the lower the viscosity and the pressure needed from the extruder to extrude the filament.

PolyFlex TPU-95A-HF high flow allows it to have a low viscosity at low temperatures, therefore for the same amount of pressure from the extruder, PolyFlex TPU-95A is able to extrude faster resulting in a faster printing speed. Contrarily to similar TPUs on the market, PolyFlex TPU-95A-HF does not require high temperature for high speed printing which also results in better cooling rate therefore better surface quality.

UV resistance property:

Ultraviolet (UV) light is probably the most damaging environment for plastics. All applications of plastics which are used outdoors are therefore at risk, from roofing and window frames to vehicles. ISO 4892-2 is an accelerated weathering test standard to measure the UV resistance ability by exposing samples to fluorescent UV.

It is worth noting that the correlation between outdoor and artificial weathering devices is very material dependent. Other variables need to be taken into consideration and therefore it can be difficult to correlate natural UV exposure in a particular location to a period of time in a weathering chamber. In theory, 72 hours in a weathering chamber could have the same effect as several months to several years in certain locations.

Bed surface

PolyFlex TPU-95A-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 TPU-95A-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 TPU-95A-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 TPU-95A-HF allows it to have a more consistent extrusion rate, similar to hard materials.

Resistance from the filament spool

PolyFlex TPU-95A-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 TPU-95A-HF high flow properties means that the filament requires very little pressure change to stop or begin extrusion. Therefore, PolyFlex TPU-95A-HF can handle similar retraction settings as rigid/hard materials.

Dry box system

PolyFlex TPU-95A-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 TPU-95A-HF in a PolyBox to prevent moisture absorption. If the filament has absorbed moisture it can be dried at 70C for 12 hours in a convection oven.

Support material

Polydissolve S1 PVA is the recommended support material for PolyFlex TPU-95A-HF.

PolyFlex TPU-95A-HF is also a great material to support itself.
