TPU 95A is a flexible thermoplastic polyurethane filament rated at 95A on the Shore hardness scale, making it the firmest and most common grade of TPU. It offers a good balance of flexibility and easy printability, which is why it’s the standard starting point for anyone new to flexible filaments.
The higher the Shore A number, the firmer the material. 95A holds its shape better and prints more reliably than softer grades, closer to a firm rubber than a stretchy band, while 90A and 85A flex and compress more but are noticeably harder to print without a well-tuned setup.
Most TPU 95A prints between 210–240°C on the nozzle, with a bed temperature of 30–60°C. Keep print speed slow, generally 20–30mm/s, since printing too fast is the most common cause of buckling and inconsistent extrusion with flexible filaments.
A direct drive extruder is recommended and gives the most reliable results, but 95A is firm enough that it can also be printed on a Bowden setup with reduced speed and minimal retraction, unlike softer TPU grades which struggle much more on Bowden printers.
Jamming is almost always caused by printing too fast, too much retraction, or wet filament buckling in the extruder. Stringing usually points to a nozzle temperature that’s slightly too high or moisture in the filament — reducing temperature by 5°C and drying the spool are the first fixes to try.
Yes. TPU is highly hygroscopic and absorbs moisture quickly, which causes stringing, surface bubbling, and weak layer adhesion. Dry it before printing if the spool has been open for more than a few days, and store it sealed with desiccant between print sessions.
TPU 95A suits phone cases, cable organisers, gaskets and seals, protective guards, and flexible joints in articulated models — anywhere a part needs to bend or absorb impact while still holding its shape well and printing reliably.
