Overture TPU Review

I’d consider standard Overture TPU 95A for grips, feet and flexible covers if your printer can feed soft filament and you’re willing to print slowly. I recommend it for small, practical projects where you can try a part, adjust its feel and print it again. Its main drawback is the preparation: drying, careful feeding and some tuning belong in your plans.

This review covers the standard 1 kg spool of 1.75 mm-diameter filament. Overture also sells High Speed TPU 95A, a separate formulation worth considering if printing time is your biggest concern.

How Overture TPU Fits The Parts You Want To Print

TPU stands for thermoplastic polyurethane, a flexible printing plastic with a rubber-like feel. The 95A label is its Shore hardness rating, which measures how much it resists being pressed into. It doesn’t tell you how easily a finished case will bend or a printed foot will squash.

For that, the shape matters too. Thick walls and a densely filled interior make a part harder to squeeze. Thinner walls and less infill—the pattern of plastic inside the part—usually give it more room to bend. A chunky grip and a thin cover can feel quite different even when they’re printed from the same spool.

That makes standard Overture TPU a reasonable candidate for a handle sleeve, replacement feet or a cover that needs to stretch over something. Start with a small version or section of your design so you can check the feel before printing the whole thing.

Be more demanding if you’re making a seal or protective case. Flexibility alone doesn’t prove that a gasket won’t leak or a case will protect a dropped device. Oil resistance and long service life also need evidence for the actual conditions your part will face.

What To Expect From Overture TPU Print Quality

Expect some tuning before you get a finish you’re happy with. Stringing, where thin strands remain between separate parts of a print, appears in owner reports of standard Overture TPU. Those reports also include successful prints, so stringing isn’t an inevitable outcome or proof of a bad spool.

One Prusa MK4 owner reported a pleasing first result at a 225°C nozzle and 50°C bed, with a 0.4 mm brass nozzle. They used a modified flexible-filament profile, a saved group of settings in the software that prepares models for printing. Drying conditions weren’t given.

An Ender-series owner reported less stringing after tuning at 20 mm/s and 215°C, but used unusually long, fast filament pullbacks between printed areas. That recipe isn’t a sensible default for another printer.

In published stretching tests, eight standard Overture TPU samples behaved similarly when pulled. They were printed at 30 mm/s with 100% infill on a Prusa MK3S with an upgraded direct-drive filament feeder and 0.6 mm nozzle. That’s encouraging for repeatable parts under those conditions; it doesn’t establish accurate hole sizes or strength between stacked layers.

For a part that must fit snugly, print a short test section first. Don’t assume a clean-looking surface guarantees the right dimensions. Likewise, scattered bumps alone don’t tell you whether the cause is moisture, the point where each layer starts or inconsistent filament thickness.

Getting Your Printer Ready For Overture TPU

A direct-drive printer is the easier starting point. Its feed gears sit close to the nozzle, so they push the flexible filament over a short distance. A Bowden printer pushes it through a longer tube, giving it more opportunity to bend or compress. Standard TPU can work with Bowden setups, but expect slower printing and more adjustment; check your exact printer’s flexible-filament instructions first.

Automatic filament-feeding accessories need a separate check. Overture excludes standard TPU from Bambu AMS and AMS lite, while Bambu excludes generic TPU from AMS 2 Pro. The AMS HT has a separate TPU bypass outlet; using that route isn’t automatic feeding.

Follow the instructions for your exact printer and accessory combination. If your required feed path doesn’t support this material, pass on the spool.

Plan for drying before printing. TPU absorbs moisture from the air, which can lead to stringing and a rough surface during printing. Overture specifies 70°C for seven hours. Check that your dryer can maintain that temperature and that the spool you’re using permits it; don’t exceed either item’s limits.

Keep the dried filament sealed with desiccant, which absorbs moisture. A sealed storage box helps keep filament dry but doesn’t replace heated drying.

For standard TPU, use the data sheet’s 210–230°C nozzle range and 20–40 mm/s print range as your starting guidance, beginning toward the slower end. Its bed range is 25–60°C, subject to the instructions for your build plate, the surface the print sits on.

Overture’s store page also displays 210–240°C and a much higher speed figure, but its data sheet, filament cheat sheet and product FAQ agree on slow printing. Don’t treat the higher store-page figure as a proven capability.

Start with the TPU profile for your exact printer and adjust cautiously. Keep part cooling enabled; the appropriate fan percentage depends on the printer and shape.

Retraction pulls filament back between printed areas to limit oozing. Overture’s product FAQ recommends turning it off or keeping it minimal because long pullbacks can stretch or buckle TPU and disrupt feeding.

If your printer’s TPU instructions call for retraction, Overture’s broader guide suggests 0.5–1.5 mm at 20–30 mm/s. Treat that as general guidance, not a universal setting for every printer.

Check removal instructions before printing, too. TPU can stick too firmly. For example, Prusa calls for a separating layer, such as glue stick, on its smooth and satin sheets when printing flexible materials, but not its textured sheet. Glue can help you remove a print, so don’t assume its only purpose is to help it stick.

Standard Or High Speed Overture TPU?

High Speed is the closest useful alternative if you’re planning large prints or repeated batches. Both versions are sold as 95A, 1.75 mm filament in 1 kg spools, but they need their own settings. Overture lists 60–90 mm/s for High Speed versus 20–40 mm/s in the standard material’s data sheet.

Those ranges don’t tell you how much sooner your part will finish. The shape, layer size and amount of plastic your printer can melt all affect the result. Don’t turn an advertised speed multiple into a promised reduction in printing time.

High Speed still needs drying and a suitable feed path. The matching hardness labels don’t guarantee that parts printed with the two versions will feel identical. If you’re switching a grip or flexible mount that already works, print a sample before committing to a batch.

Compare equivalent spool sizes when buying, and include any dryer you need in your budget. For occasional small parts, faster printing may matter less than getting a dependable setup. For repeated jobs, investigate High Speed with your intended model and printer profile.

Who Should Consider Standard Overture TPU?

I’d consider standard Overture TPU for a first flexible project on a compatible direct-drive printer, provided you can dry the spool and accept a few trial prints. Grips, feet and fitted covers give you a straightforward way to judge whether its feel and finish suit your needs.

I’d pass if you need unsupported automatic feeding, expect a soft, foam-like part from the hardness label alone, or need proven sealing or protective performance. If slow printing is the sticking point, investigate High Speed before buying standard TPU.

Your next step is to check your printer’s TPU instructions, the permitted feed route and your drying equipment. Then choose a small test that includes the thickness or opening your finished part needs. A successful test of that detail will tell you more about suitability than a generic demonstration print.
