With concerns about our ability to feed 12 billion people by the end of the century, one engineer is looking to replace conventional food with something produced by a 3D printer, and he’s getting a grant from NASA to create a prototype.
A US start-up company has a solution for people who want to eat meat, but don't want to harm animals either: 3D printed meat. The 3D printing technique is already being used to create things from bike parts to chocolate to dental crowns and bridges. And scientists are working towards using 3D printing to make organs for transplant.
