Perhaps the best example of what can be made with TPU filament is a phone case. It gives you all the qualities that you need, with it being flexible and easy to put on. It has a level of shock absorption and also a high level of durability.
That’s just a good example, but it can be used for a lot more than that. Automotive parts are another good example due to the resistance of the material to heat and oil. The likes of seals, plugs, and gaskets can be a great use of TPU.
Beyond that, you have wristbands, insoles, door stops, straps, caps, cable ties, grips, and a lot more. Those qualities of strength and flexibility give it fantastic versatility.
