Comment on Can too good adhesion be countered by lower bed temps?

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

    Yup. My kid found the idea hilarious when I explained why I’d swiped a washable glue stick from the arts and crafts box.

    It hangs on well, but also makes removal easier.

    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.

      glue or hairspray

      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

    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.
