If we can digitize a human with a milling machine, it seems to me that we ought to be able to fabricate robots in a single pass. I doubt they'd be the clanking tin monsters of last century. Instead, they'd be rubbery humanoids, hydraulically or pneumatically powered. At first, they'd probably have electronic brains and hydraulic pumps built in the usual fashion, but perhaps with the invention of extremely high-resolution fabricators, even those could be printed or extruded along with the rest of the unit. Eventually, they might literally walk off the assembly line.
