Does the ABS chamber temperature melts PLA?

Prusa Enclosure MK3S+ Acrylic Case Box Tent Kit | eBay

If you intend to get an MMU2 at a later date that is. The only thing the Prusa lacks is an enclosure box or case to make full use of its capabilities. In a market awash with inexpensive printers full of crappy parts that wear out quickly, everything about the Prusa i3 is quality.

This Prusa enclosure product description says the chamber temperature can melt PLA, Is that even possible? Just how hot it really gets in there.

It doesn't melt PLA, but at around 50-60°C PLA starts to become soft and pliable. And those temperatures are easily reachable on a printer chamber at ABS temperatures.

Melt? no. But IME (with PLA+) it can get warm enough to make it warp pretty badly. I'd reprint any critical parts out of ABS/ASA.

PLA can also creep under pressure / tension. I printed the external PTFE hanger for my 2.4 out of PLA before I got the enclosure complete, then reprinted in ASA after the enclosure. I noticed a distinct bend in the middle when I replaced it.

I've been going back through and reprinting any parts that I made in PLA now that I can reach 50° chamber temps.
