Polymaker TPU Filament 1.75mm Black - Flexible TPU95

In this review of Polymaker PolyFlex TPU95 filament, the bottom line is simple: this spool is for makers who need a stiff-yet-elastic TPU that prints on most desktop FDM/FFF machines without hardware changes. The reviewer found the 95A Shore hardness and reported over 400% strain-to-failure deliver a rubbery, resilient part useful for gaskets, phone cases, and wearable parts. Packing and spool handling reduce moisture and tangles, and prints run reliably when settings are tuned, making it a strong choice for hobbyists and small workshops who value dependable flexible filament.

Key Features

• Customizable flexibility: The 95A Shore hardness offers a firm but elastic feel that holds shape while stretching reliably for functional parts.
• Broad printer compatibility: PolyFlex prints on nearly all desktop FDM/FFF printers without hardware modifications, keeping setup simple for most users.
• Tangle and moisture-free packaging: The filament arrives dried, vacuum-sealed with desiccant in a resealable bag and carefully wound to reduce tangles during printing.
• Reliable layer adhesion: The material produces strong interlayer bonds and a rubbery texture that yields consistent, bubble-free parts when using recommended settings.
• Wide application range: Suitable for wear seals, gaskets, watch bands, phone cases, and small drone or bike components where flexibility and durability matter.
• Simple print settings: Recommended nozzle 210 C-230 C and slow print speed make it accessible for first-time TPU users willing to tune their slicer.

Who It's For

Polymaker PolyFlex TPU95 is aimed at hobbyists, makers, and small shops needing a tougher, slightly stiff flexible filament that still stretches well; it is especially useful for functional parts like gaskets, keyring cases, and protective covers. Users who print wearable items such as watch bands or insoles will appreciate the material's shape memory and durability when parts are sliced and printed carefully.

Those who require ultra-soft, limp elastomers or who expect flawless self-adhesion without any tuning may want to consider other TPU grades; some users report mixed adhesion to itself and a perception of relative stiffness compared with softer TPUs. Beginners should also be comfortable dialing in slower speeds and ensuring proper filament handling to avoid nodes.

Pros & Cons

Pros

• Excellent compatibility with many desktop FDM/FFF printers so no special hardware is needed.
• Dry, vacuum-sealed packaging and spool winding reduce moisture and tangles for easier printing.
• Strong layer adhesion and robust rubbery texture produce durable, functional parts.
• Wide practical use cases from gaskets to wearable items thanks to 95A hardness and high elongation.

Cons

• Some users report mixed self-adhesion and that the filament can feel stiff compared with softer TPU grades.
• Requires slower print speeds and careful feeder handling to avoid nodes and feeding issues on some setups.

Frequently Asked Questions

Does this TPU need a special extruder?
No, PolyFlex TPU95 is designed to work on nearly all desktop FDM/FFF printers without hardware modifications, though a direct drive or guided filament path helps.

What nozzle temperature should I use?
Use a nozzle temperature between 210 C and 230 C and a bed temperature of 25 C to 60 C, with slower print speeds for best results.

How is the spool packaged to prevent moisture?
The filament is dried, vacuum-sealed in a resealable bag with a desiccant and carefully wound to reduce tangling; keep the tip secured and use spool side holes to prevent nodes.
