POST IT Note glue, an amazing discovery ?
September 30, 2013 02:47PM
Hi all,..

here's a thing.
I was printing earlier today and while waiting for an upload (I always set my bed to hot, then kick off the upload, it uploads while the bed heats, saves me messing about removing / inserting SD cards)

I wanted to brush a few bits off my kapton tape over aluminium bed. I picked up a post it, intending just to use the paper to brush it off, and I accidentally wiped the gluey side on the bed ;-)

Guess what.. I've been printing all day on the same kapton tape.

I've just been wiping my post it note over now and then. Ok the bed does now look a *bit* smeary in places, but the prints are sticking nicely.

anyone tried anything similar ?

I think the discovery is the same phenomenon of elmers glue, hair spray, dissolve acetone -ABS, the binder inside certain blue tapes, etc.

What you are doing is making the surface SO SMOOTH upon contact with molten polymer, that the surface bonds to it reversibly, much like suction cup, or caulk on a ceramic. These are possibly vanderwaals forces, london dispersion, and hydrogen bonds.
