Spread on the glue stick then spread it around with a damp paper towel. Heating
the bed dries it to a smooth coating.

Never thought I would use my 3D printer as much as I do. I've also broken glass
plates with PETG and nylon sticking too
well (pulls out bits of glass) - I get mirror tiles to print on - very
inexpensive, but I still don't want to break them...
The key I've found is getting the glass perfectly clean - (A-IPA with a
chem-wipe should squeak) excellent for PLA - but
other plastics can stick too well or not well enough - so for those I use
Elmers glue stick - it breaks instead of the
glass - the problem is getting complete and consistent coverage. Supposed to
be made of an acrylic polymer - wish I
could find it as a spray.
I've printed gaskets using TBU - and used several nylon types - I've found
Nylon-X to be amazingly strong - (a bit
pricey - but printing something that is brittle isn't cheap in the long run)
These days I use nylonX unless there is a
good reason not to.. ( I use a vacuum chamber to dry filament - even PLA -
makes a lot of difference).
