Lovely idea, but we can't even 3D print plastic reliably and that's 20 years old. I don't see how this can scale atomic printing until they can utilize 1000s of parallel print heads, none of which make a mistake that would short out the circuit.

Printing a lithium battery is also a nice idea, but is much easier to accomplish by layer-based lithographic-style methods -- the ultimate in parallel "printing" -- currently used in chip fabrication factories for 3D chips.

Haven't we gotten better at 3d printing?

Yes, better, but they still mess up, producing what’s called a spaghetti print.
