Posted · PLA print stuck to glass plate

Hello

So every time I print with PLA, if I don't put glue on the glass plate the print won't stick to it, but if I do use it, it sticks too much and I can't remove it without doing some damage to the print. I've tried heating the print bed, running warm water, and using a spatula but none worked perfectly.

Does anyone have any different method that may help me?

Thanks

    Hey there. 

     

    One good method is to put it in the freezer and it will pop straight off. 

    Are you trying to remove it while the glass is still hot or warm as it will still hold on stong if this is the case.

    Normally PLA should stick on the glass without additional glue. I only had issues when the glass wasn't clean. Cleaning it with Isopropanol did help then. I usually wipe the glass plate with Isopropanol every few weeks and don't use any glue stick.

     

    Instead of putting the whole plate in the freezer, you also can try to cool down the print with a can of compressed air while it is still in the printer. I do that sometimes when I am too impatient to wait for the print to cool down on its own 😄

    Don't overdo the freezer - a minute at a time is usually enough. The technique works on a contraction/expansion basis so if the freezer doesn't work after a minute or two, take it out and leave it to get to room temperature again and if needs be, repeat.

    Thank you for the tip

    The glass is completely clean but it still doesn't stick. I'll try using compressed air on my next print, thank you
