Invetech 3D bio-printer is ready for production, promises 'tissue on demand'

Say hello to "the world's first production model 3D bio-printer." What you're looking at is a machine capable of arranging human cells and artificial scaffolds into complex three-dimensional structures, which result in such wonderful things as replacement liver and kidney tissue, or such simple niceties as artificially grown teeth. All we're told of the internal workings is that the bio-printer utilizes laser-calibrated print heads and that its design is the first to offer sufficiently wide flexibility of use to make the device viable. Organovo will be the company responsible for promoting the new hardware to research institutions, while at the same time trying to convince the world that it's not the fifth sign of the apocalypse. Maybe if the printer didn't have a menacing red button attached to it, we'd all be a little less freaked out by it.
