The thing a lot of people don't get about 3D printing is that it has been around since the early 80s. And unlike semiconductors which follow Moore's Law, not much has changed in the past 30 years except some of the earlier patents have expired. So the printers good for printing cheap plastic junk, like figurines, now only cost about $1K. SOURCE: My company has been using $1-500K 3D printers for the past 15 years.
