Can too good adhesion be countered by lower bed temps? (lemmy.world)

My prints get very good adhesion to the bed, especially when doing prints with large adhesion areas. So good, that after the print is done, I actually have to wet the surface with alcohol and put it in the freezer for it to let go! (edit: I print with PLA)

My question is, if the adhesion could be a bit less violent, if I lower or increase the bed temperature? I have an ender 3 v2 with the original glass bed (it has some black layer on top of the glass).

I know that there are tons of alternative beds that I could buy, but I'd rather keep this bed if I can counter the too strong adhesion

Adhesion can be better, but it also acts as a release agent. If you are printing PETG on glass always use glue, for PLA it shouldnt be needed.

I am in deed printing with Pla but it sticks waaaay too well onto the surface

In my experience PLA just pops off the clean glass when cooled to room temp (holds extremely well if bed is at 45C or more). I have some tips, but only to improve adhesion xD You can maybe try less squish on the first layer (lower flow rate or increase nozzle distance a bit) or just use thin layer of glue. Too low or too high bed temp can ruin bed adhesion, but feels like wrong approach imo, still worth a try

glue or hairspray
