Surgeon Anthony Atala demonstrates an early-stage experiment that could someday solve the organ-donor problem: a 3D printer that uses living cells to output a transplantable kidney. Using similar technology, Dr. Atala's young patient Luke Massella received an engineered bladder 10 years ago; we meet him onstage.
It's exciting to see the development of 3D printing move from little objects to human organs. This advancement illustrates soon many objects will be printable from home - with a printer we drop resources into, or even a sorter that breaks apart other objects to salvage resources for new products.
