      It’s funny cause I always kinda thought that was a bit of hyperbole regarding uv exposure.

      Made a bracket to fix a broken mount for our back seat cam in our car. Printed in pla just to test the dimensions. It worked so I left it in the car. Didn’t make it a single day. Completely warped.

      Reprinted in petg and it’s been going strong for 2 weeks now.

        Wouldn’t heat be the main problem in a car? On a sunny hot day a car can get up 130+ easy, add in the heating from the sun actually hitting the print and it’s not hard to imagine it could get warm enough to become a little malleable.

          Definitely heat - pretty much all windshields/windows nowadays block UV, otherwise the dash/seats/etc. would also get wrecked way quicker than they do, not to mention drivers getting sunburn even with the windows up.

          Hmm the car is parked in the garage so I just kind of assumed it was the UV during driving but yea I guess it must have been the heat.

          Yep. I was under the impression that UV radiation causes PLA to get brittle over time. But heat causes it to warp very quickly.

        in a car? during summer? Ngl that sounds more like a temperature issue than a UV one. PLA doesn’t degrade that quickly and it can get pretty hot inside a car during the summer
