15 Gadgets That Will Change the World

3D Bioprinting Machines

We know that 3D printing technology can be used to do more than make odd plastic trinkets. Thanks to a group of bioengineers around the country, we now know that the technology can also be used to develop human tissue. Dubbed Bioprinting Machines, these devices can build patches of skin, blood vessels, and cartilage using living cells. Though years away from clinical use, one company, Organovo Inc., has already released a commercial 3D bioprinter that cost "several hundred thousand dollars each," according to the Wall Street Journal. It's not the hardware that's holding the technology back, however, Hod Lipson of Cornell's Creative Machine Lab, says, "We have machines that can make almost anything, but we don't have the design tools/ In bioprinting, there is no computer-aided design software for body parts."
