"...So here’s my point. Such progress in the industrialization of 3D-printing technology is probably the best thing that could happen to the Maker movement. It’s only a matter of time before spin-off technologies start trickling down into the hands of hobbyist and neighborhood makers at affordable prices. Greater R&D investment will in time surely yield a steady flow of more capable and presumably cheaper home printing technology, including new machines, enhanced design software, more and better fab materials and deeper processing knowledge. These innovations should help bring 3D-printing and additive manufacturing firmly into the mainstream and maybe into your own home.
Real-world replicators have taken a lot longer to materialize than I’d thought; it’s been nearly half a century since Star Trek first appeared. (Yeah, they also promised me jet-packs…) But the replicator revolution seems to be happening at last. Now where are those beers?" from source: http://boingboing.net
