I'd say the two go hand-in-hand. The holy grail of the maker movement is microfactories where individuals or small teams can produce local-scale consumer products out of their garages/basements to sell to their communities. That by definition is a small business with a small warehouse. :) From a marketing standpoint alone the ability to rapidly produce metal cases for things would give products an air of quality that you could never match with a plastic 3D printer and might cost too much to CNC. Between this and the costs of pick-and-place machines coming down I'd love the ability to design/build my own consumer electronics products and sell them out of my garage.
