Obligatory I hope that’s not pla yadda yadda
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.
