Basically the title. I'm curious is PLA prints are more prone to warping in warmer weather as they age.

​

Reason for the question is I was repairing a cosplay prop I'd printed out of PLA around this time last year. It had been damaged in travel and needed some extensive repairs. After re-gluing the break and applying some bondo to the seam, I left it outside to cure. Unfortunately I got called for work and had to leave home for a few days, accidentally leaving it on my balcony. Well... I live in Arizona and it got a bit hot out, I think over 100F, and my prop deformed pretty badly, as well as cracked along my seam lines.

I know it's not good practice to expose PLA to higher heats, but heat down here is kind of unavoidable. I feel like I'd probably left the prop out while I was making it but didn't have warping anywhere nearly this dramatic.

​

Alternatively going forward I've been looking into switching to PETG, but it looks like the temps to print it and PLA are relatively close - would PETG suffer similar warping issues in high heat? I know ABS is stronger but I just don't live in a place where I can vent my printer
