Gregory Ferenstein covers 3D printing for TechCrunch from two opposite angles. The life saving one:
Doctors 3D-printed an emergency airway tube that saved a 20-month old baby boy’s life. After imaging the boy’s faulty windpipe, doctors at the C.S. Mott Children’s Hospital printed 100 tiny tubes and laser-stitched them together over the trachea.
and the life killing one:
A new bulletin from the U.S. Department of Homeland Security warns that lethal, undetectable 3D-printed firearms may be “impossible” to contain, Fox News reports After a Texas law student designed and released digital blueprints for the world’s first fully printable gun, the files have allegedly been downloaded more than 100,000 times, despite a domestic ban on distributing the files from the U.S. State Department.
3D printing could be a life changer in a number of areas: implants, synthetic tissue, and even houses. I’d hate to slow down innovation on those fronts because humans can also print guns.
