Polymaker High Flow TPU Filament 1.75mm Clear - Fast, UV Resistant

Our review of the Polymaker High Flow TPU Filament 1.75mm Clear focuses on flexible prints that need speed and outdoor durability. This filament is aimed at makers and small-scale manufacturers who want a firm, rubbery material with excellent flow for faster print speeds and good UV resistance for exterior use. The single biggest reason to buy is the combination of high-flow extrusion and a Shore 95A hardness that keeps parts tough and shape-stable while still offering meaningful flexibility.

Key Features

• High-flow formulation: Allows faster printing without compromising strand consistency, so larger flexible parts can be produced quicker than with standard TPU.
• Shore 95A hardness: Produces a sturdy, rubbery feel that holds shape for functional parts like gaskets and plugs while still providing some give.
• UV resistant: Makes printed components suitable for outdoor applications where sun exposure is a concern.
• Tangle and moisture-free packaging: Supplied vacuum-sealed with desiccant and a resealable ziplock bag to keep filament ready to print and reduce failed prints from moisture.
• Excellent layer adhesion: Delivers strong interlayer bonding that minimizes delamination in flexible prints when correct settings are used.
• Wide application range: Works for wearables, protective parts, and small mechanical components such as watch bands, insoles, keyring cases, and drone parts.

Who It's For

This filament is best for hobbyists, designers, and small production shops who need a firmer flexible material that prints faster than many TPUs and can withstand outdoor exposure. It is particularly useful for printing functional parts where durability and UV resistance matter, such as bike components or protective housings.

Those seeking ultra-soft, highly elastic TPU for very flexible wearables or soft-touch prototypes should look at lower Shore options; similarly, users with printers that struggle with flexible filaments may prefer a stiffer thermoplastic or a different feed setup before attempting this high-flow TPU.

Pros & Cons

Pros

• High flow enables faster print speeds while maintaining consistent extrusion.
• Strong, rubbery Shore 95A material offers good shape memory and durability for functional parts.
• Vacuum-sealed, desiccant-packed spool helps prevent moisture and tangles out of the box.
• UV resistance makes it suitable for outdoor applications.

Cons

• Firm 95A hardness may feel stiff for users expecting very soft TPU items.
• Some users report mixed self-adhesion behavior, so tuning retraction and temperature may be required.

Our Verdict

The Polymaker High Flow TPU 1.75mm is a strong choice for users who need a fast-printing, UV resistant flexible filament with a firm Shore 95A feel. It delivers reliable layer adhesion, consistent flow, and practical packaging that reduces moisture issues, making it good value for functional, outdoor-capable parts when the slightly stiff feel is acceptable.

Frequently Asked Questions

Is this filament suitable for outdoor parts?
Yes. The formula is UV resistant, which helps printed parts hold up better in sun-exposed conditions.

What nozzle and bed temperatures are recommended?
Recommended nozzle temperature is 200 C to 220 C and bed temperature 25 C to 50 C, with fans on and speeds from 40mm/s to 100mm/s.

How is the filament packaged to prevent moisture?
The spool is dried, vacuum-sealed, and supplied in a resealable ziplock bag with desiccant to limit moisture absorption.
