Comment on Want some advice on which filaments to use

I’ve read that PLA will sag over time pretty much no matter what you do. I assume it would be terrible for the first use case. I assume you can’t design around it but I’m happy to be proven wrong.

I almost exclusively use PLA and I’ve had no trouble but all my stuff is indoors. I’ve heard that it doesn’t do as well in the elements so for anything outside, I’l probably look at using petg which from what I’ve read, holds up pretty well outside.

It’ll only sag if it heats up and starts to deform, like if you leave it in the sun. It’d probably be just fine under a conpressive load like that.

  Do you know what temperature range that is? Is 35 to 30C fine?

    Yeah. “glass transition temperature” is the term to look up
