Wow, that is current state of the art in printing!
Basic dream is to create a Star Trek replicator, a shop with a 3D printer, you walk in and request a particular phone or other gadget, shopkeeper downloads a pattern, prints it off and sells it to you. To do that you need to be able to print in multiple materials to create electronics, mechanics etc.
3D printers are a spin-off of this.
Latest is ink jet printing of electronic circuits, one application that has taken off is printing transistors onto glass for Oled manufacture.
O stands for Organic, organic polymers exist that allow creation of electronic components, 3 dots give NPN parts of transistor, other dots give conductive part for connections etc.
Same technology is also being used in USA and shortly Europe to produce disposable mobile phones, usually about $20 to buy, size of a credit card, no display, minimal keypad, plug in handsfree, receives texts, can't send texts, receives calls, one hour calling time then throw in the bin.
Basically injet technology creating smaller dots than normal using special bio polymers, printing onto paper base.
Currently not small enough (silicon is currently on pico metre dot size, I think this technology has got to micron dot size), currently not fast enough, currently not robust enough (bio polymers break down quicker than silicon).
Your current printer is probably running at 3600 dpi = 141 dots per millimeter, dot size approx 0.7 mm. 1 uM = 1000 dots per millimeter.
I don't think RepRap will be going this way, but I could be wrong.
I'm afraid this is all from my head so please excuse inaccuracies.
