Agreed.Quote
Thoughts?

Is there a particular advantage of using extruded plastic and solder over say, drawing or printing the circuit in ink, on a bare copper PCB and then using chemical to etch it?

Or you could possibly cover the bare copper with tape and use the reprap to cut ( with a rotating exacto-knife like blade ) the circuit for etching.

A precise enough milling head could even cut away the copper from a bare pcb and drill the holes too ( which is certantly nothing new, but it's tested and proven to work well ).

Correct. There's no preliminary advantage. Adrian et. al. have focused on trying to innovate a new process rather than first demonstrate success and workflow with a way to do the old technology that actually works, by you know, bolting a marker on to their machines and just etching some pcbs.

Yup. I've read that it's expensive and slow compared to other methods. CNC drilling is supposed to be really helpful, though.

I figured that these efforts were mostly driven by the desire to keep the project true to it's sustainable roots.

Why would this process necessarily be slow or expensive? Couldn't you use a fine tip bit and just trace around all of the lines, leaving the unused space as ground?

Laser toner is actually super-fine black plastic powder - maybe we could just print a layer straight onto the copper with our reprap and etch?
