PLA print royally stuck to print bed glass

Recommended Posts

Hello all. After my first print not sticking too well to the bed and warping, I put some watered down prit stick on the glass bed. Now the print has stuck royally to the bed, I have tried prying it loose with a razor, and soaked it for a few minutes in warm soapy water and no luck. I can barely get a razor underneath it!

Anything else I can do? Trying to not damage the glass bed.

Put it in the freezer. REally. After 20 minutes take it out and immediately try to remove the part (before the part or glass warm up). It might just fall off (I'm always surprised when it does - I never learn).

Usually though I use a putty knife with one corner sharpened razor thin. Glass is tough - usually only diamond will scratch glass. It's the printed part you are more likely to damage.

For your next prints, I would suggest that you give the "salt method" a try. (=Wiping the glass plate with very salt water, prior to printing. No glue, no hairsprays.)

For PLA this gives a very strong bond when the glass is hot, but no bonding at all after cooling down to room temp: the models just pop off. No more need to take the glass out of the printer, no more recalibrating the build plate...

I use this since more than a year, and have had no problems since: no bonding problems, and no removing problems.

For the full description, see the PDF-manual at:


If you try it, could you let us know how well (or how bad) it works?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
