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

You could always try it…

I use PEI instead of glass and find that a thin layer of glue stick works great for helping sticky materials release.

So you use glue to make adhesion worse? That's very interesting!

I use the washable gluesticks for my polycarbonate prints. I just put PC prints under warm water for a few minutes and they pop right off. Gluesticks generally reduce bed adhesion though IME, so it's a fine line to walk; I never use gluesticks with PETG for example because then the parts don't stick to the bed enough.
