Hi, is it possible to print small blades that will function as a tension spring and if so, what filament should i use?
Any help is appreciated!
Grtz

In models where a printed torsion spring is used, PLA is most often recommended. You don’t want to use PETG as it is too flexible for this purpose.

Thank you, any idea how ASA would behave?

Probably too flexible, is my thought, supported by Polymaker Material Database chart of bending modulus.
