What this is is a sort of inkjet printer that uses ABS plastic to "print" prototype parts. Things like this have been promised for decades and are only now just becoming fact.
Feed in a CAD file and some materials and some time later you open the door and remove your part. It's probably not quite that simple, but even so, this is a huge leap forward. At various times in my life, I have been involved in what we used to call "rapid prototyping" and there was nothing really rapid about it, except perhaps the pace of the cursing.
It's just cool. And it's only $18 grand!! MissM? It's almost my birthday time.
