One of the most annoying thing with the printing is to figure out how to stick your model to the print bed. I read many articles, forums, posts and mails about it and there are many ways starting with a perfect clean heated glass surface just with the right temperature, hairsprays, glue sticks, blue tape, etc. Some of them works on PLA, other works on ABS. Some of them are available in my local store but didn’t know what kind of spray or stick to use, some of them I did not able to find at all (in my country there is no such thing as a blue tape).
Still, I found a “thing” that works best with ABS and PLA, and it is worldwide available. A “White Glue”, also know as “Wood Glue”, “C-200” or just the white glue that child uses in schools.
This glue is water based, so a water can be used as a thinner. You can apply it as it is (thick) on the glass surface (aluminium surface should work as well) for stronger bond, or you can reduce it to look and feel like a low fat milk. Just apply a thin coat with brush and turn your bed heater to dry out the glue (it dries quickly).
I have printed many parts with a small contact area, without a brim, and all of them were attached very good to the surface. After the print is finish, let the bed cools to room temperature and with a little force you can remove the part very easy. When the bed is hot, the part will be very hard to remove.
One coat of glue is enough for many prints. No glue is left on the part (like the hair spray) when the part is removed. The glass can be cleaned with a simple window spray cleaner and some kind of tissue, cloth or kitchen paper. The glue dissolves from the cleaner. PC screen cleaner works as well (that’s what I use).
Hope this info helps someone. If I new it earlier, it was going to save me a lot of nerves
