Polymaker PolyFlex TPU90

PolyFlex™ is a family of high-quality flexible materials. It provides the perfect solution for applications where high flexibility and durability are required. PolyFlex™ TPU90, created from Covestro’s Addigy®️ family, is a thermoplastic polyurethane (TPU) based filament designed to provide great flexibility without compromising on printing speed. It also has the ability to resist ultra-violet (UV) light or sunlight.

Features

Flexible & Durable – PolyFlex™ TPU90 features a “Shore A” hardness of 90A, enabling production of softer parts in comparison to PolyFlex™ TPU95. 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™ TPU90 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 585% combined with excellent wear, tear and impact resistance; PolyFlex™ TPU90 is an extremely durable choice for 3D printing custom over grips, vibration dampeners, footwear, phone cases and end use products.

Formulated For 3D Printing - Using Covestro’s Addigy® family as its base material, PolyFlex™ TPU90 is specifically engineered for 3D printing to combine durability, flexibility and UV resistance. PolyFlex™ TPU90 delivers a soft and flexible 3D printing filament that is compatible with a wide range of desktop FDM/FFF 3D printers.

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

PolyFlex TPU90 Flexible 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™ TPU90 displays a shore hardness of 90A, softer and more flexible than grades of 95A.

  • Excellent flexibility and durability.
  • Excellent UV resistance.
  • Excellent impact resistance and resistance to wear.
  • High elongation at break over 585%.
  • Minimal printing requirements when compared to other flexible filaments.
  • Improved flow behavior in comparison to some other TPU90 grades.
  • Exhibits excellent dimensional stability.
  • Using Covestro’s Addigy® family as its base material, Polymaker has engineered and optimized PolyFlex™ TPU90 specifically for 3D printing.

With a diverse portfolio of materials ranging from high performance plastics to unique aesthetic solutions, Polymaker will continue to add cutting edge materials to its ever-growing portfolio.

At the core of Polymaker is their research & development laboratory, this is where all Polymakers materials are formulated and fine-tuned from the ground up to create the best in class 3D printing materials. Polymakers precision testing equipment combines the latest advancements in technology to ensure they are ahead of the game.


Industry Leading Quality Control

Polymaker 3D Printing Filament

PolyFlex™ TPU90 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™ TPU90 is wound on Polymakers 750g 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™ TPU90 is packaged in a vacuum sealed aluminium foil resealable bag to ensure your filament is moisture free. Like all other TPU based filaments, PolyFlex™ TPU90 is mildly hygroscopic so we recommend keeping this bag for filament storage. 

Printing Settings
Nozzle temperature 210˚C - 230˚C 
Build surface material Almost any surface (I.e Glass, Buildtak, PEI etc.)
Build surface treatment None required, can apply PVA glue or Magigoo Flex to the build surface
Build plate temperature 25˚C - 60˚C
Cooling fan ON
Printing speed 30mm/s - 60mm/s
Recommended support material (optional) PolyDissolve™ S1

It is recommended to slightly increase the extrusion multiplier (+0.2) 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™ TPU90 is dried to ensure the best printing quality and filaments are vacuum sealed to protect the filament from moisture. When not in use PolyFlex™ TPU90 should be stored away from sunlight in the packaged resealable bag.

PolyFlex™ TPU90 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™ TPU90 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™ TPU90 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.

We have full MSDS and technical data sheets for PolyFlex™ TPU90 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™ TPU90 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: Can PolyFlex™ TPU90 be printed at large scales without warping?
A: PolyFlex™ TPU90 offers excellent dimensional stability and can certainly be printed at large scales without warping. Please note while we have never experienced warping with PolyFlex™ TPU90; we recommend a consistent room temperature as printing in a cold environment or with poor first layer adhesion can cause any material to warp. Using Magigoo Flex can improve the adhesion of PolyFlex™ TPU90 to the buildplate.

Q: What support materials can I use with this product?
A: Polymaker’s PolyDissolve™ S1 filament is the recommended support filament for PolyFlex™ TPU90. If your 3D printer is not equipped for multi-material, self-support can be used.
