Are you using a lot of spray? You only need a quick once over or two, then let that dry. You don't need to mist every time, either.

^ this. A couple of light coats should be good for multiple prints. I usually do one light coat from side to side, let it set up, then another light coat front to back to ensure even coverage. one application will usually last me for nearly a week of heavy printing. when things start to not stick anymore, I clean it off with windex and start over

i use single edge razors (bought a 100 pack at local home improvement store) to get under an edge or corner of a print to work it loose all the time - just use a bit of common sense with them - they are very sharp after all. =P

I use a razor on large prints too, but never had glass come off.

but it was so strong it took a sliver of glass off with the print...

Morganism; Carl_m1968: Looks like I am going to get some sort of razor.

I occasionally have the same problem. If you have a removable glass plate (which it sounds like you do), the glue is made to wash off the hands of kids easily in the sink. Use warm water and the glue will turn purple again, and then eventually wash off. You can also wash the residue off the bottom of your print. Just don't make it too hot.

I also bought a 4" paint scraper. I will slide this under the corner of a print and gently work it until the print comes free. BE VERY CAREFUL! Without securing the glass, you do not want to cut your other arm. Sometimes when the prints are cool, I have to give a stiff, short jab at the base to get under the print. Sometimes they will pop clean off.

Additionally, if you use ABS and let it cool sufficiently, it will usually pop off on its own because it shrinks just a little as it cools.

I have started using a glue that as far as I can see is the same as Elmers Purple Disappearing Glue. I can't get Elmers because they don't stock it in the UK but this stuff seems to be identical barring the text on the gluestick.

Anyway, it sticks the PLA print to the glass really well, no more curling... However getting it off can be a problem.

I have had some limited luck with tapping it off with the handle of a screwdriver but prints with a larger contact area with the glass get stuck hard. I have tried putting it (with the glass) in warm water overnight but with no luck and I poured 90 celcius water over it this morning to try to remove it but ended up warping the print.

Any better ideas? I have broken two glass plates so far and am going to go and buy a stock of them but obviously it would be better if I could just get the print off the glass reliably.
