Self replicating machine: apparently possible but not yet done because there's too many parts. But 3D printers can apparently make complex and many-parted things out of a plan and a tub of plastic grains, can we do it now?

Including circuitry in the definition of the printer? I'd be surprised if we can build a printer right now or in the near future that can print its own control circuitry, and without that it's not really self-replicating.

OTOH 1: Chips are so cheap and ubiquitous that in practice this might not be that much of an issue (although this is kind of cheating; if we put real manufacturing effort into making 3D printers, they'll be cheap and ubiquitous as well).

OTOH 2: I guess that if we move away from contemporary computer hardware technology it can be somewhat possible --- something like a huge mechanical computer controlling the printer from 3D printed slabs of code? (run from a manual crank?) It'll look more like "The Differential Engine" than grey goo, that's for sure.
