Large-scale low-cost metal 3D printing. We're _very_ close and it could be a game changer for a number of industries since the price for one unit is very close to the mass-production per-unit cost. It could allow custom-fit application or modification of a design on a per-customer level for things that would in the past require significant outlay. If I need a new part for something that's no longer supported, no problem. If I want to test an idea, fine. etc.
