Organs on Demand? 3D Printers Could Build Hearts, Arteries

Off-the-shelf 3D printers could one day help create living organs to aid in repairing the human body, researchers say. Scientists have developed a way to 3D print models of various anatomical structures, including hearts, brains, arteries and bones. Another application for this innovative technology could be food printers, reminiscent of the replicators seen on the TV show "Star Trek," the scientists added.
