OK, here is the *most complex* 3D printer ever built.
Does anybody know about the Cubital Solider?
It weighed about a ton.  It was a fabrication shop in a box:

https://www.efunda.com/processes/rapid_prototyping/sgc.cfm

The Additive Manufacturing (AM) technology the Cubital Solider used
was called Solid Ground Curing.

It did photolithography of masks it used for exposing photopolymer layers
and it had a *mill* in it for finishing the layer surfaces.

I think it is pretty clear that it would be an almost trivial step to add
copper circuit trace plating.  And you would have multi-layer PCB
fabrication.

Why not?
Add an electronic component pick-and-place capability?
Connection soldering?  Might be a bit more complex.
But what the heck -- the machine is already way complex.
So, it's like a trivial upgrade.

It is the machine I think is the closest to being able to build itself
or other robots of different types.
