This is overblown. We still need food, we still need heavy engineering, we still need nanotech. Yes, there are some simple things that can be manufactured differently to how they had been in the past, but even those are still not free. The printers are not free, their consumables are not free and they can't produce more than a small fraction of the things we currently buy. I think this tech will be revolutionary, don't get me wrong, but I don't think everything is going to be free nor do I think capitalism is going anywhere fast (at least, not on account of 3d printers!)
