Smart idea: [WayBack] How-to Make Your Own 3D Printing Goo.
It is a large (22g) Elmer’s glue stick dissolved into a cup of warm water.
After applying it with a paper towel, the 3D print sticks to the warm printing bed well, but comes off easily from a cold printing bed.
It is quite easy to make. 1 cup water and 1 large 22g Elmers glue stick. I put both in water and let sit thinking it would dissolve on its own. After several hours I got impatient and put it in the microwave and heated it.(45 seconds I think). That did the trick and was only left with a few big clumps that I broke apart with my fingers to finish the dissolving.
To apply I just dip a paper towel in the solution and wipe on the bed. It leaves an extremely light layer of glue on the bed that PLA sticks very well to. When the bed cools the parts have very light adhesion to the bed. If the bed is hot it takes some force to get off.
