The obvious difference that jumps to mind is the enclosure…
PLA is easy to deal with but it still can curl up where layers start and end.
Then the head comes around again, bumps slightly into the previous mess and with every round things get worse.
Often this can be limited by making adjustments to the print temp, e.g. increasin or decreasing it by a few degrees.
Leaving the door open with PLA can help as well but one should make sure there is no draft blowing through.
