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 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.
Flexible & Durable - PolyFlex™ TPU95 features a “Shore A” hardness of 95A, producing flexible parts with excellent durability. Thanks to 3D printing, a model can also be made
more or less flexible depending on its design and infill.
Fun & Functional - The flexible properties of PolyFlex™ TPU95 open up a new dimension of what one can do with desktop 3D printers. Wearable’s, hobby parts, prosthetics, custom gaskets, jigs & fixtures; with PolyFlex™ TPU95 the possibilities are endless.
Wear & Tear Resistance - Featuring an elongation at break result of 330% combined with excellent wear, tear and impact resistance, PolyFlex™ TPU95 is commonly used for a variety of demanding applications.
Formulated For 3D Printing - Flexible filaments are known to be more difficult to work with when compared to rigid filaments. PolyFlex™ TPU95 balances flexibility and usability to provide a unique 3D printing filament that is compatible with a wider range of desktop FDM/FFF 3D printers.
Uncompromised Quality - Polymakers leading quality control process and rigorous inhouse testing ensure reliable printing and consistency across spools and batches.

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 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.
- Excellent flexibility and durability.
- Excellent impact resistance and resistance to wear.
- High elongation at break up to 330%.
- Minimal printing requirements when compared to other flexible filaments.
- Exhibits excellent dimensional stability.
PolyFlex™ TPU95 is a popular material among both hobbyists and professionals interested in 3D printing flexible parts. It's commonly used by hobbyists to 3D print shock absorbent camera and drone parts, the footwear industry to print upper shoes, soles or insoles, professionals to create flexible jigs and fixtures, and is commonly used to print custom gaskets.
The soft and flexible nature of PolyFlex™ TPU95 continues to provide endless possibilities for creatives and engineers alike.

Design considerations in combination with different infil densities and infil patterns can be used to control the overall flexibility of the final print. Rectilinear and Grid infil patterns are some of the most popular choices for general purpose projects and readily available in most slicers. Advanced three dimensional infil patterns such as Cross3D and Gyroid offer some benefits in the form of uniform flexibility. 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.
PolyFlex™ TPU95 offers fantastic printability compared to many other TPU grades and demonstrates excellent dimensional stability, enabling users to print large flexible parts without warping. An enclosure isn't required however may be beneficial in particularly cold or drafty environments. PolyFlex™ TPU95 prints with excellent inter-layer adhesion and it's compatibility with specialized support materials, enabling users with a dual extrusion 3D printer the ability to complex structures and geometry.

Flexible filaments such as TPU tend to benefit from slow and consistent feed rates.
Note: Printing conditions may vary with different printers and nozzle diameters.
Storage & Drying:
Before packaging, PolyFlex™ TPU95 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 should be stored away from sunlight in the packaged resealable bag.
PolyFlex™ TPU95 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 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 can be dried in a preheated convection oven at 65˚C for up to 8 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.

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.
PolyFlex™ TPU95 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. With some extruder set ups a larger nozzle (0.5mm or 0.6mm) may be recommended to reduce pressure in the nozzle and improve extrusion consistency.
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.
Q: Can PolyFlex™ TPU95 be printed at large scales without warping?
A: PolyFlex™ TPU95 offers excellent dimensional stability and can certainly be printed at large scales without warping. Please note while we have never experienced warping with PolyFlex™ TPU95; we recommend a consistent room temperature as printing in a cold environment or with poor first layer adhesion can cause any material to warp.
Q: What support materials can I use with this product?
A: Polymaker’s PolyDissolve™ S1 filament is the recommended support filament for PolyFlex™ TPU95. If your 3D printer is not equipped for multi-material, self-support can be used however support removal will be difficult.
Don't know where to start? Or which filament will suit your application? We have a broad range of support options including telephone support. Contact us today!
