A Indian-origin mechanical engineer has developed a 3D printer that makes pizza fit for astronauts.
Mechanical engineer Anjan Contractor had won a 125,000-dollar-grant last year to build a prototype 3D printer designed to print food for astronauts on long missions, the Verge reported.
In the video from late last year, the 3D printer takes food "building blocks" to make the crust, cheese, and so-called "protein layer" for the dish, all cooked while being printed out.
Contractor had promised last spring that the cartridges the printer uses would be able to last for 30 years.
