PolyFlex TPU95-HF UV resistant TPU Filament

PolyFlex™ is a family of high-quality flexible materials. It provides the perfect solution for applications where high flexibility and durability are required. 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.

Features

Rapid 3D Printing - The high flow of PolyFlex™ TPU95-HF allows it to have a low viscosity at low temperatures, therefore for the same amount of pressure from the extruder, PolyFlex™ TPU95-HF is able to extrude faster resulting in a faster printing speed. Contrarily to similar TPUs on the market, PolyFlex™ TPU95-HF does not require high temperature for high speed printing which also results in better cooling rate and therefore better surface quality.

Flexibility - PolyFlex™ TPU95-HF features a “Shore A” hardness of 95A, a hardness carefully chosen which allows it to not stretch excessively when pulled by the extruder. Thanks to 3D printing, a model can also be made more or less flexible depending on its design and infill.

UV Resistance - 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, PolyFlex™ TPU95-HF offers excellent UV resistance so that the appearance and mechanical properties of your 3D prints are not influenced negatively by UV light.

Wear & Tear Resistance - Featuring an elongation at break result of over 460% combined with excellent wear, tear and impact resistance; PolyFlex™ TPU95-HF is an optimal choice for manufacturing functional end-use parts, rapid-protoypes, prosthetics, custom gaskets, jigs & fixtures.

Formulated For 3D Printing - Using Covestro’s Addigy® family as its base material, PolyFlex™ TPU95-HF is specifically engineered for 3D printing to combine flexibility, UV resistance and fast printing speed for professionals and manufacturers.

Uncompromised Quality - Polymakers leading quality control process and rigorous in-house testing ensure reliable printing and consistency across spools and batches.

Industrial products can require specific equipment and skills.

PolyFlex TPU95-HF 3D Printing Filament

TPU (Thermoplastic polyurethane) is a flexible 3D printing material. One way to indicate the flexibility and softness of the filament is by looking at the Shore hardness. PolyFlex™ TPU95-HF displays a shore hardness of 95A, a hardness carefully chosen which allows it to not stretch excessively when pulled by the extruder, improving overall printer compatibility.

The flow rate of flexible materials has always lagged far behind rigid materials which has limited the reliable printing of TPU to slow speeds. PolyFlex™ TPU95-HF (TPU95 High Flow) is an industrial TPU filament with a higher melt index of 9.3 (g/10min at 185°C), which allows it to have a low viscosity at low temperatures. Therefore for the same amount of pressure from the extruder, PolyFlex™ TPU95-HF is able to extrude faster resulting in a faster printing speed.

This of course is achieved without compromising flexibility, PolyFlex™ TPU95-HF offers very similar mechanical performance to PolyFlex™ TPU95 and even offers some additional advantages. 

  • Capable of high speed printing.
  • Excellent UV resistance.
  • Excellent flexibility and durability.
  • Excellent impact resistance and resistance to wear.
  • High elongation at break up to 460%.
  • Minimal printing requirements when compared to other flexible filaments.
  • Exhibits excellent dimensional stability.

Boasting a recommended printing speed up to 100mm/s, the rapid printing speed of PolyFlex™ TPU95-HF enables both designers and manufacturers to produce functional prototypes, manufacturing jigs and end use parts much faster than before. Depending on the printer design and part geometry it is even possible print at speeds such as 140mm/s and even 200mm/s!

Polymaker PolyFlex TPU95-HF

Typically with most TPU filaments it is recommended to use a direct drive printer for the best printing results, however the high flow properties of PolyFlex™ TPU95-HF allows the material to achieve high printing speed even on indirect drive printers. Furthermore the high melt index has enabled some users to increase their retraction settings without the increased risk of jamming.

PolyFlex™ TPU95-HF is commonly used across a wide variety of applications to print flexible components such as over molded soft grips, gaskets, grommets, protective case inserts, footwear and fixtures for vibration isolation and damping applications.

Design considerations in combination with different infil densities and infil patterns can be used to control the overall flexibility of the final print. The fastest print speeds with PolyFlex TPU95-HF are best achieved by printing with linear infil patterns such as rectilinear, grid or lines. With these infil types the part will display great flexibility and the print head won’t need to change direction as often, reducing time spent accelerating and decelerating.

Three dimensional infil patterns such as Cross3D and Gyroid deliver uniform flexibility and are a great infil to choose for users who prioritize flexibility. Fast print speeds can still be used however as these infil patterns change direction quite often the print head will spend more time accelerating when printing infil. Using a moderate infil with structural infil types such as Hexagon and Triangles can increase part rigidity, enabling the production of jigs and impact-resistant parts which prioritize durability rather than flexibility.

Ultraviolet (UV) light is a damaging factor for plastics and long exposure changes the properties of the material often leading to brittle, weak, and discolored parts. All plastics which operate outdoors are therefore at risk which is usually mitigated by post processing parts with a protective coating. The UV resistance of PolyFlex™ TPU95-HF makes it an excellent candidate for automotive and outdoor applications and the color difference of PolyFlex™ TPU95-HF is imperceptible after being exposed to fluorescent UV after 72 hours under ISO 4892-2 weathering test standard.

Industry Leading Quality Control

Polymaker 3D Printing Filament

PolyFlex™ TPU95-HF like all other Polymaker materials is manufactured using state-of-the-art polymer processing technologies and equipment. Polymakers rigorous minimum 8 quality control processes ensure industrial standards of reliability for a consistent customer experience.
Tolerance: Polymakers custom developed extrusion, control and monitoring solutions to ensure filament tolerance and roundness meet Polymakers strict quality standards.
Reliable Mechanical, Colouring & Printing Properties: Every batch of filament products are tested to ensure all quality specs (melt flow, softening point, mechanical, diameter, round-ness) are met.
Drying & Vacuum Sealing: Before packaging, all Polymaker filaments are dried to a moisture level of < 0.1% to ensure the best printing quality and are vacuum sealed to protect the filament from moisture. All vacuum packaged products are left for 24 hours before boxing to ensure they are leak-free.


Packaging

Transparent Spool: PolyFlex™ TPU95-HF is wound on Polymakers 1kg transparent spools. With the transparent spool, it is easy to see exactly how much filament is left for your next printing project.
Resealable Bag: PolyFlex™ TPU95-HF is packaged in a vacuum sealed aluminium foil resealable bag to ensure your filament is moisture free. Like all other TPU based filaments, PolyFlex™ TPU95-HF is mildly hygroscopic so we recommend keeping this bag for filament storage.

It is recommended to slightly increase the extrusion multiplier (+0.15) to ensure a more consistent extrusion.

Note: Based on 0.4 mm nozzle and may vary with different printers and nozzle diameters


Storage & ​Drying

Before packaging, PolyFlex™ TPU95-HF is dried to ensure the best printing quality and filaments are vacuum sealed to protect the filament from moisture. When not in use PolyFlex™ TPU95-HF should be stored away from sunlight in the packaged resealable bag.

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 effect the quality and mechanical properties of the final prints. We recommend storing PolyFlex™ TPU95-HF in the PolyBox™ or a dry cabinet during printing to prevent moisture absorption which will lower the quality of the print. The PolyBox™ keeps the filament at dry conditions (relative humidity of 15% or less). 

If you hear popping sounds and notice that the surface quality of your print is uneven or the color is not consistent, this is a likely indicator that the filament has absorbed too much moisture. Spools of PolyFlex™ TPU95-HF can be dried in a preheated convection oven at 70˚C for up to 12 hours. Results may vary depending on the accuracy of your oven so please be conservative. For more information about filament drying please read our user guide.

Note 1: ΔE measures the change in visual perception of two given colours. On a typical scale, ΔE value will range from 0 to 100. ΔE of 1.0 is the smallest colour difference the human eye can see, so any ΔE less than 1.0 is imperceptible.
Note 2: 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.

We have full MSDS and technical data sheets for PolyFlex™ TPU95-HF and all other Polymaker products. Contact us to enquire!

The typical values presented in Polymakers data sheet are intended for reference and comparison purposes only. Due to the nature of 3D printing they should not be used for design specifications or quality control purposes.


Compatibility

PolyFlex™ TPU95-HF has been engineered with compatibility in mind to print excellently on a wide range of 3D printers.

Flexible filaments tend to have more specific feeding requirements so it is recommended to make sure your filament guide system is smooth and with minimal bends to reduce drag. Any unnecessary drag can result in under extrusion so we also recommend bypassing features that apply pressure to the filament such as mechanical filament detection switches.

Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer.


FAQ

Q: Is 100 mm/s the fastest speed I can print PolyFlex™ TPU95-HF at?
A: It is certainly possible to print PolyFlex TPU95-HF at much faster speeds, including 140 mm/s and even 200 mm/s! Not all 3D printers are equal and at these speeds the quality of your 3D prints will very much dependent on your 3D printers design.

Q: Are high speeds with PolyFlex™ TPU95-HF only possible with a direct drive extruder, or is it possible with an indirect drive ?
A: Usually it is recomended to use direct drive printer 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)

Q: Can PolyFlex™ TPU95-HF be printed at large scales without warping?
A: PolyFlex™ TPU95-HF offers excellent dimensional stability and can certainly be printed at large scales without warping.
