Nathan, I asked before but we never went anywhere with it. Can you please add all the cool new PLA materials to the list we can choose from? I have received requests for bronzeFill from another site that shall remain nameless. I just got some copperFill and I preordered ProtoPasta's stainless steel & iron PLA filaments. I'll also get some brassFill when it gets released. I also got a request for high temp PLA. Any way we could list ret to list these?
