PEI seems to be quite well known and readily available in the USA, but is expensive and hard to find here in the UK. I ended up importing a sheet from amazon.com. See [miscsolutions.wordpress.com].

Yes, but that's only a step between. And the printbed will not be flat this way.

What way? I use a thin sheet of PEI attached to 4mm float glass, which gives me a nice flat surface.

That way you have 3 layers with undefined levels of flatness stacked above each other. I do not say it wont work, maybe its good enough for you, thats ok! We all are only working with hights of the tenth of a millimeter anyways. But a milled printbed is absolutely flat. Maybe thats somehow relevant.

It is odd that it isn't readily available in the US. Is there a particular vendor you guys buy yours from in Germany?

I'd be happy if I could find PEI that was as easy to apply as BuildTak. That 468MP tape is a royal pain, it gets all bunched up on the sides. I ordered some 12x12 sheets of it to see if that's any easier to work with than the 1 inch strips.

Assuming that PEI can be kept free from damage, how long before the surface looses its ability to grip the print? Is there a way of returning it to a good grip and clean release?
In ABS, and presumably in other plastics as well, the adhesion seems to be in a layer possibly only one molecule thick. Untreated float glass has excellent adhesion but it looses it after only a few prints. Any kind of cleaning seems to be only marginally effective although a few months of UV rich sunlight seems to work quite well. Kapton tape lasts a bit longer before becoming poisoned and, like glass, no solvent brings it back to the hot grip or clean release of a new film. Surfaces applied as a liquid such as ABS slurry or Wolfbite seem to be very unpredictable.

I bought 2 of these PEI coated ALU beds on eBay. One is not flat so I haven't used it. The other one has indentations and blisters where I have printed ABS on it. The PEI doesn't seem stable at ABS temperatures (110/ 250). I prefer diffused glass as I get a better finish on my parts and it never degrades.

Skimmy - after reading through, I think I must have missed something. Hopefully you can clarify this for me?
PEI has been around for some time - but your talking about PEI covered/coated Aluminium - Is this normal aluminium sheet or aluminium plate? And how thick?
When you say "coated" - do you mean the Ali plate is "dipped" in PEI so there is a thin even film of PEI on every surface or is it a piece of aluminium with a PEI sheet applied to the top surface with an adhesive sheet? I dont understand what is "special" about this if it is just a sheet of PEI applied to an ali plate.
As you mention, PEI is not good with Nylons, Peek or PC, there are other surfacces that work with all the common filaments aswell as Nylons PC and Peek that are tougher than PEI and ever lasting, and parts self release when cooled down with that same "crack" when it releases.
Do you have a direct link? I did a brief google search but I dont think i saw your plate in the results (it was only a brief search).
