A quote:

Parmod VLT inks and pastes - which include silver, copper
and a variety of other metal compositions - are quickly
and easily applied to industry-standard substrates such
as silicon, polyimide and FR-4, by printing processes such
as screen printing, laser mill and fill, computer-controlled
micro-dispensing, and ink-jet printing.The result is fully
additive circuits and interconnects.

Don't know anything about it (cost, printertype, etc), just found the site by accident :-)
