The PWB process allowed the wires to be stacked up, crossed over, etc. Didn't have layers of cards.
As I said tho, its been surpassed by gluing multilayer cards together.

...or has it...?

Well, maybe that's not the same thing, but on the wikipedia page for "printed circuit board":

http://en.wikipedia.org/wiki/Printed_circuit_board

...they mention a (patented) process called "MultiWire" which sounds close to what the OP desires (in a certain manner), which was (per the article) still available from Hitachi as of 2010 - I found this:

http://www.hitachi-chemical.com/products_pwb_05.htm

So maybe it is still possible to get...?

Other than the patented process, I wonder how difficult it would be to homebrew a machine to do something like this (probably not easy, certainly)...

/loved the old "cordwood" PCB fab method shown on that wikipedia page...
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

Some people in the reprap project have tried this. They printed a plastic circuit board with channels for tracks and filled them in with another extruder using Field's metal at first then solder later. Take a look here: http://blog.reprap.org/2009/04/first-reprapped-circuit.html

Might not be quite the level of precision you had in mind though :)

Maybe take the reprap idea and use solder paste to fill the track, either from syringe that squeezes it out under printer control also, or hand squeegied out like when applying paste with a mylar/steel stencil.

The Panasonic link above mentions using copper paste. Could you solder to that later?

I find it harder to express logic in English than in Code.
Sometimes an example says more than many times as many words.
