What is TPU?
TPU (thermoplastic polyurethane) is a flexible, rubber-like plastic that is very hard to tear or break. We stock two hardnesses: 95A, which is firm like a skateboard wheel, and 90A, which is softer and grippier, closer to a shoe sole. How flexible the finished part feels also depends on wall thickness and infill, so the same material can make a firm bumper or a soft pad.
Design tips for TPU
- Thin walls flex more: 0.8–1.2 mm for a soft part, 2 mm or more for a firm one.
- Lower infill makes a softer, more cushioned part.
- Avoid tall, thin unsupported features; flexible plastic wobbles while printing.
- Tell us how soft it should feel and we will suggest settings.
Nozzles: 0.4 mm as standard, 0.6 mm for larger parts printed faster. General tolerance is ±0.5% with a lower limit of ±0.5 mm. More in the design guide.

TPU 3D printing FAQ
How flexible is 3D printed TPU?
It depends on the hardness, the wall thickness and the infill. TPU 95A with thick walls is firm like a hard rubber wheel; TPU 90A with thin walls and low infill is soft and squeezable.
What is the difference between TPU 95A and 90A?
The number is the hardness. 95A is firmer and holds its shape better, which suits bumpers and mounts. 90A is softer and grippier, which suits pads, feet, seals and cases.
Can TPU be used for gaskets and seals?
Yes. Printed TPU gaskets and seals work well for dust, splash and vibration sealing. Tell us the mating surfaces and we will suggest thickness and infill.
Does TPU hold up outdoors?
TPU resists abrasion, oils and impact well and is used on drones, vehicles and equipment. For rigid parts in constant sun, ASA is the better choice.
