Just like with inkjet printing, you could have a printer head for different types of material - one for plastics, one for glass or some other clear composite, and one for metal and/or silicon. As the printer head passes back and forth, it would spray the material in picoliter droplets (or smaller) in the exact spot it needs to be. Different combinations of heads would make the casing, the printed circuit board, the CPU, and then the OLED screen and clear screen. I don't see the battery happening this way, but everything else could.
I think that currently, the screens for large-screen OLED TVs are actually printed by a printer onto a substrate. So, that part of the printing process is already in place. The part where metal would be involved would be the newest part, and would be a big challenge.
