Hi, I’m searching for a fillament with a similar hardness/resistance to PLA but which doesn’t plasticly deform when bent for longer periods of time.

This is for a wearable, specificly the c3cat cat ears. I printed mine out of PLA but they got too loose after 2 days of wearing.

I already got reccommended TPU 100A, but I worry that it’s too soft.

Thankies :3

    So… PETG and ABS/ASA- as already mentioned here- will probably be the best bet.

    But if your printer can handle it (i don’t know how difficult it is, mind,) polypropylene might be a good option. For example, the tic tac lid is made out of ppe.

    Both PETG, ABS/ASA will provide a hard/strong plastic finish and much better creep (plastic deformation over time) than PLA. PETG is easier to print if your don’t have a (heated) enclosure, and fumes are less toxic.

    TPU has no strength, but very tough and pliable.

    Polypropylene, hands down. Most plastic thingies that’re meant to bend constantly without wearing out are PP. Like those little straw caps attached to big drink tumblers? The bendy part, if not the whole hinge, is usually PP i think. I think generally things that could be described as “living hinges”.

    I will say though, that it’s easily the most difficult filament I’ve ever had the displeasure of printing. It absolutely REFUSES to stick to literally anything but other polypropylene lol. What you do is just put some packing tape on your bed, that stuff’s made of PP as well.
