What Are the Blue 3M Platform Stickers?

[Bobbler]

Well the standard black Buildtak is available direct from their online store here - http://www.buildtak.com/product/buil...build-surface/

Certainly sounds like the right stuff, and to prove a point Buildtak do custom colours and logos on the stuff too:

I installed the FF version of the Buildtak and am having some issues with it. The parts I print stick too well to the surface. I have the nozzle height adjusted to about 0.25mm and the heated bed to 80 degrees C, so I'm not sure what's going on. I printed a 1" x 2" part and had to chisel it off. That left an air pocket between the Buildtak and the bed. I'll try it out with some different settings before switching back to the Kapton tape.
