Do you need specialty bed adhesives or is your pantry already hiding a perfectly suitable 3D printer bed coating? Let’s find out!
Usually the articles here are an illustrated version of the video’s script, but this one only came together once I did the experiments. So for your convenience, here’s the summary of how each one of these materials did!

Pasta Water
Once dried, pasta water creates a rigid, but tacky film that adheres well to PLA and PETG

Sriracha Sauce
Smells awesome when warm, but doesn’t hold down 3D prints

Tooth Paste
Creates a rubbery film that might stick to 3D prints, but easily peels from the glass

Soy Drink (Soy Milk)
Creates a hard film that PLA or PETG do not stick well to

Egg White
Gives a thin, clear film that sticks well, but peels off the glass with the print

Pineapple Sauce
Sticky. Gooey. Gross.

Hairspray
Depends on the exact brand used, but the one I got worked well.

Spray Paint
Gives surprisingly good adhesion, but removing prints also removes bits of the spray paint

Cling Film
Does not cling to glass well enough to hold down prints

Wood Glue
Dries hard and smooth and sticks well to the glass and prints

Packing Tape (PET Film)
Does not stick for PLA, but works well for PETG

Glue Stick
Proven solution for PLA and PETG

Clean Glass
Sticks well enough to PLA, but depending on which glass you get, PETG might take out chunks of glass when removing prints

Duct Tape
With its waxy surface, prints do not stick

3D Lac
Good adhesion and strong hold, even once cooled down
