At which point does self-assembly and 3d printing overlap? Is there some minimal viable size for a 3d printer to be shrunk down to, aka, cellular level? Is there diminishing returns or does one eventually just go to nanites for this?

> Is there some minimal viable size for a 3d printer to be shrunk down to, aka, cellular level? Great, not only chemicals, bacteria/virus, nuclear radiation, drones with guns can kill us all very efficiently, bot soon nanobots can devour us alive.

In principle you can pick-and-place individual atoms with an electron microscope. But if you think macro-scale 3D printing is slow, you'll be flabbergasted by how much slower this is.
