PUSHING INNOVATION
3D printing has already begun to transform several industries. The health and medical field has made several breakthroughs thanks to 3D printers, which have been used to create hearing aids, custom leg braces and even a titanium jaw at a fraction of the cost of a traditionally manufactured equivalent. NASA is also interested in using 3D printers in space, to let astronauts print whatever they require, cutting down on the amount of supplies and equipment required on the initial launch. Perhaps the most intriguing development is in the area of 3D-printed food. Modern Meadow, an American startup is researching how to print a steak. The process involves animal cells being grown in a cell culture media, which is then combined and printed out as muscle and fat, and can then be matured and conditioned into a familiar and tasty meat product.
