Rise of the replicators - New Scientist
MakerBot is one of a range of desktop manufacturing plants being developed by researchers and hobbyists around the world. Their goal is to create a machine that is able to fix itself and, ultimately, to replicate … MakerBot and most of its kin are essentially a cut-price reinvention of the 3D printer. While professional machines still cost upwards of tens of thousands of dollars, a coalition of academics and tinkerers has created versions that do much the same thing for much less. Anyone with a few hundred dollars and some spare time can build their own 3D printer from a set of plans distributed free on the internet.
