Isn't PETG much more durable than than PLA? PETG is less strong in the sense that is can flex, but it is much more impact resistant and less brittle than PLA I thoguht. Also, in something like a case with screw holes, even slightly too big screw will crack the case, while PETG will usually be okay. I could be wrong–I'm pretty new to 3D printing.
- vorpalhex 6y agoPETG isn't as hard as PLA and is less fragile, with minor flex. It's main downside is that it's a pain to glue without special glues as the usual suspects (cyanoacrylate, epoxy, etc) don't usually like to stick to it.

He measures various kinds of strengths (tensile, compressive, impact, young's modulus etc). I highly recommend it. But when people say strength they usually mean static tensile strength.
