What about commercial 3-D printing? A large scale facility that can afford to invest in the latest and greatest printers could turn a profit in just-in-time prototyping, small runs of specialized custom designs, etc. Email us your design and we'll have 100 units ready for you to pick up in the morning. Overseas manufacturers can't beat that. They're using glass, metals, and fabrics now. It seems like only a matter of time before you can order up almost anything at the corner print shop. If I were China, I'd be trying to get upstream of this trend as soon as possible and become the main supplier of the printers in the world.
