use Ice Spray to remove objects stuck on glass

[Kermit65 0]

Hello

I print PLA on glass. I first clean the glass with water, then I use window cleaner and finally provide a thin layer of 3D Lac. This procedure provides superb adhesion and fine surfaces, but unfortunately sometimes objects are stuck on the glass plate. An easy method to release them from the glass is using ice spray: After cooling down the object and the glass surrounding it, you will hear a crackling noise and the object almost falls off the plate.

You can then reuse the glass plate without the need to go through the cleaning procedure again.

Hi Andreas,

I use 3DLac as well and I notice that the spray works great but if you get drops of 3DLac they will stick a lot more so try paying attention to those especially with XT because it can chip your glass surface.

ice spray: is it not just compressed air that causes ice when over pushing it?

I wonder if you can try to use the ice spray on the underside of the glass to see if it still works. This way the ice spray would not get in contact with the piece. I usually just rinse the underside of the glass with cold water in the sink and it helps to lower the temp even more.
