I personally would think heated brushed stainless steel bed would work properly. If you can control either the room temperature or build a shroud around the bed or even better have a temperature controlled build chamber it should make the stainless ideal in those circumstances. I have seen where people were printing on stainless in such a manner, once the print is done they simply let it cool, the SS shrinks at a different rate than any plastic and causes the part to pop off the bed with no real fuss. I am going to experiment with my own printer at a later time with SS, the nice thing about it is you can use steel wool to polish it up if you happen to get crud on it.
It seems to me that thermal shock is the biggest problem people have with their printers.
