I stumbled on a 3D printing tip. To make it easy to remove a print, the video showed a user, using a spray bottle of 50% water and 50% alcohol.
I gave it a try this weekend and I'm very pleased with how well it works.
they say it works with glass, aluminum, glue stick and painters tape.
What I suspect happens is the alcohol lowers the water density just a bit and helps it seep into the tiny cavities between the build plate and printed part by capillary action. This can be a mighty if tiny force in it's own. The fluid expands and in about 30-50 seconds the part will pull or pop off by itself or require just a little levering using a paint scraper.
They do caution that in one instance a piece of glass broke away with the part. but I suspect that doesn't happen often.
It does make the print part come off, you can even hear a little popping sound sometimes as the fluid gets drawn in.
Most times the pieces needed a little restraint (finger on it as I worked to pry it free)
I have very good adhesion with glue stick, so good I had to change the bed temp up and down a few times to get the part loose, and use a razor blade often. This has changed the game.
Good luck if you try it. I'll see about posting the youtube link later if people want it.
