Polymaker TPU Filament 1.75mm Shore 95A 0.75kg Black, PolyFlex TPU95, UV Resistant Review (2026)

Updated September 14, 2026 · Research-based review

Our verdict

Polymaker's PolyFlex TPU95 is a well regarded 95A flexible filament with tight tolerance and consistent winding, sold as UV resistant for parts that spend time outdoors. It comes on a smaller 0.75kg spool than most 1kg TPU rolls and costs more per gram, a fair trade for buyers who value predictable feeding over the lowest price.

What we liked

  • + UV resistant TPU holds up better on outdoor mounts and covers
  • + Shore 95A PolyFlex is a well-regarded, predictable flexible filament
  • + Polymaker consistency reduces feeding surprises on flexible prints

Trade-offs

  • - 0.75kg spool holds less filament than typical 1kg spools
  • - Premium pricing per gram compared with SUNLU or OVERTURE TPU

Who this filament is aimed at

PolyFlex TPU95 suits printer owners who want a dependable, well documented flexible filament for phone cases, grips, gaskets and outdoor-facing parts like mounts or covers, and who are willing to pay more per gram for that consistency. Polymaker positions it as UV resistant on this listing, which matters for parts left outside where standard TPU can discolor or become brittle over time from sun exposure. A direct drive extruder is recommended for the best results, so owners running Bowden printers should expect to tune retraction and speed down rather than get factory-fresh performance immediately. Buyers focused purely on cost per gram or who need a full 1kg spool will find this a less efficient buy than SUNLU or OVERTURE's larger TPU rolls.

What the spec sheet shows

The filament carries a 95A Shore hardness rating and prints at 210 to 230C nozzle temperature with a bed temperature between 25 and 60C, and Polymaker recommends a print speed of 20 to 40mm/s, a fairly conservative range even for a TPU marketed toward smoother printing. Dimensional accuracy is rated at +/- 0.03mm, matching the tolerance most competing 95A TPUs advertise, and Polymaker states elongation at break above 330 percent with tensile strength around 29 MPa, giving a sense of how much the material stretches before failing. It ships on a 0.75kg spool, smaller than the 1kg standard common across many rival TPUs, wound to resist tangling and sealed with desiccant in a resealable bag to keep moisture out between print sessions.

Printing and storing it

As with any TPU, a short and constrained filament path between the extruder and hotend produces the most reliable feeding, so a direct drive setup avoids the buckling that plagues flexible filament on long Bowden tubes. Reducing or turning off retraction helps prevent the skipping and grinding that soft filament causes when an extruder tries to pull it back quickly. Because the bag reseals, owners can return unused filament to its desiccant packaging between prints rather than leaving the spool exposed to room humidity, which matters more for TPU than for PLA since it absorbs moisture faster. If prints start showing surface roughness or small bubbles after storage, a short run through a filament dryer typically brings the surface finish back.

How it compares with SUNLU and OVERTURE TPU

Against SUNLU and OVERTURE's high speed 95A TPUs, both of which the site scores the same as each other and just above this Polymaker roll, this PolyFlex trades a smaller 0.75kg spool and higher price per gram for claimed UV resistance and Polymaker's reputation for consistent winding and feeding. Neither SUNLU nor OVERTURE market UV resistance on their high speed TPU lines, so for parts that will spend real time outdoors this is the more deliberate choice of the three despite ranking slightly behind them on the site's overall value score. For strictly indoor parts where cost per gram matters more, the larger 1kg SUNLU or OVERTURE spools stretch further for less money.

Verdict on PolyFlex TPU95

This is a solid pick for outdoor-facing flexible parts or for anyone who values Polymaker's consistency and is willing to pay a premium for it, especially on a direct drive printer where the tight tolerance and reliable winding show up as fewer jams. It is a weaker value choice for pure indoor use where SUNLU or OVERTURE's larger, cheaper 95A TPU spools cover the same printing needs for less money per gram. Bowden printer owners should tune settings carefully regardless of which TPU they choose, since the printer's filament path matters as much as the filament itself.

Frequently asked questions

Is PolyFlex TPU95 good for outdoor parts?

It is marketed as UV resistant, which makes it a more deliberate choice than standard TPU for parts that will be exposed to sunlight over time, such as outdoor mounts or covers.

How big is the spool on this Polymaker TPU?

It ships on a 0.75kg spool, smaller than the 1kg spools common on many competing TPU filaments, which affects cost per gram.

What print speed does Polymaker recommend for this filament?

Polymaker recommends a print speed of about 20 to 40mm/s along with a nozzle temperature of 210 to 230C for reliable results.

Does this TPU need a direct drive extruder?

A direct drive extruder is recommended for the best feeding results, though it can still be printed on a Bowden setup with reduced speed and retraction.
