Idea: Automobile Paint Shop Powder Coated
I don't know if anyone has access to a paint shop. I wonder how a spring steel sheet coated with standard powder coated paint would work for 3d pirinting.

The "power coated" sheet Prusa is selling has a polyethylene coating.

Why no? Standard powder coating is pretty durable. We use it on launch pads to easult romove rocket motor debree and provide a slick surface but no too slick surface.

It's certainly possible, but I don't know if commonly used powder paint formulas have been tested for their bed adhesion, so there's a good chance it just wouldn't stick well or would stick too well to certain materials. That said, I believe temperatures for curing a powder coat paint are not that high, lower than the hotend gets to, so it could be that at higher bed temperatures, you would actually be softening the powder coat on there.... which would likely not end well.
I think the rocket motor stuff survives because the short duration of the heat, so the surface temperature of the finish is only really hot briefly, not sure it would seem so durable with an extended 110C bed temp print, for example.

there are high temp ceramic coats used on exhaust manifolds and the like but they are glass powder based and fused at very high temperatures and then you are back using a pyrex glass build surface... fusing such a ceramic to a steel sheet would defeat the major reason for using one as you flex it the glassy surface will crack an flake off. that isis you could get past the warping problem caused by the high temperature fusing... getting a flat sheet at the end of the process would be quite a trick... i understand that the temperature used in the current PC sheet process was one of the early problems with the process... I would love to learn the whole process they are now using to yield a few thousand sheets a month. you would think that by now they would have found a way to increase production....
