    Skip the glue. I’ve found it’s just gunk that separates the filament from the print bed, worsening adhesion in my testing. Clean your print bed with rubbing alcohol before hand.

    99% of printing issues with PLA are solved with a thin film of glue stick.

    IPA does not remove oils, it solubilizes them and then they deposit back down again when it evaporates. Soap and water is better because it removes oils and plasticizers.

      You don’t dump alcohol on the plate and then let it evaporate. You put it on a paper towel or microfiber cloth and rub the plate so the oils are transferred to the paper towel.

      Dish soap can be problematic because many brands include oils to be soft on hands. Palmolive is named because it has Palm oil in it. Dawn has Palm oil too
