3D printers have been around for over a decade, actually. They are only just beginning to become affordable to consumers, though. Even so, the cheapest 3D printer can cost several hundred dollars, plus the cost of materials.

In other words, unless you buy a super-expensive 3D printer, don't expect lots of detail in your models. Stuff like detailed facial features will need to be handled either by hand or by a more potent industrial 3D printer (which can cost well over $ 10 000).

Have you ever seen a 3D printer at work? You'll probably be impressed by how coordinated and fast the whole process is. It's like each component has a production planning circuit to maximize its efficiency. Here's quick look, if you're interested:
