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.
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

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