7 days agoTPU is what I’d suggest. You don’t need a enclosure and it should work for what you want. It’s a finicky material though so be prepared to spend some time getting to know it, figuring out it’s temps and speeds is a must for good prints.
TPU pretty completely bonds between layers, there’s not the same risks associated with pla and petg. Printing TPU can be a bit of a hassle so if you’re using it to prototype make sure you tune your profile for TPU. I think it’s a great idea.
