Epson prints multilayer circuit board with inkjet

Adapting printing techniques to manufacturing may allow some very cool small-batch, custom tech products in the future, and Espon seems to have taken things one step closer by printing a 20-layer circuit board with inkjet technology:
Epson recently succeeded in producing a 20-layer circuit board sample by using an inkjet system to alternately "draw" patterns and form layers on the board using two types of ink: a conductive ink containing a dispersion of silver micro-particles measuring from several nanometers to several tens of nanometers in diameter, and a newly developed insulator ink.
Will we be downloading the latest GPU design and printing it out in 20 years? Hmm. (Thanks Slashdot.)
