Prusament TPU 95A is Prusas own in-house made filament. The whole manufacturing process is closely monitored and tested - they guarantee ±0.06 mm precision and highly consistent color. You can inspect the parameters of every spool we made at prusament.com. Ch

Prusament TPU 95A is a durable material with flexible properties and extreme wear resistance. It offers a precise and consistent diameter, which is by far not a common thing among flexible filaments. The Prusament TPU 95A polymer structure (ether diol type) slightly differs from most TPU filaments (ester diol type). This difference gives this material several advantages in both mechanical and chemical resistance. The Prusament TPU 95A offers very low moisture absorption and high hydrolysis resistance. Its high elasticity and impact resistance remain even at low temperatures (as low as -50 °C). Also, this material is resistant to microbial degradation, comes with good temperature resistance (HDT 78.6 °C at 1.80 MPa), and great chemical resistance (mostly to oil and grease).

Before printing, learn about print surface preparation in our dedicated article and material table.
Soft and bendable at thin layers, strong and durable at thick layers
High print reliability with little to no stringing
Precise diameter
Good at printing bridges and overhangs (compared with other TPUs)
Great wear resistance
Flexible and durable at sub-zero temperatures
High resistance to hydrolysis and microbial degradation
Some extra tweaking before printing may be required (depending on your printer)
Printing with a smooth sheet requires a separation layer
Drying may be necessary when stored in high-moisture conditions
Large prints tend to warp
Don’t print TPU directly on the smooth PEI sheet to prevent damage. We recommend using Satin or PA Nylon sheet instead. If you need to use a smooth sheet anyway, don’t forget to apply a separation layer onto it.
Sometimes you may encounter some stringing – this is usually caused by long storage in a humid area. Dry the filament as described in our online Help article, then store it in a drybox. Some of the stringing can be removed during the postprocessing with a lighter or a heat gun.
In thin layers with low infill, TPU is very soft and flexible. In thick layers, it becomes strong and virtually indestructible. If you want to print soft parts, use less dense gyroid infill. If you need durable and wear-resistant parts, try printing with more perimeters and high infill.
This TPU 95A is made in-house at Prusa Research.
This 1.75mm filament has a manufacturing tolerance of ± 0.06 mm.
Before printing, make sure the surface of the heat bed is clean as described in the 3D Printing Handbook.
