Perhaps the wafers are expensive, but you get quite a number of chips per wafer, so the cost per CPU isn't that much. And when you look at less complex parts - simple logic chips, LEDs, even PV - the cost is pretty low.

Also, if I understand it correctly, the tech isn't limited to "machining" parts of uniform composition. It can create microstructured composites. Think e.g. creating something like a seashell: Seashells Get Their Strength from Interlocking 'Bricks'
