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.

The $125,000 grant gives Anjan Contractor and his company, Systems & Materials Research Corporation, six months to create a prototype.

Contractor ultimately expects to see a 3D printer in every kitchen, replacing food with powder and oil cartridges loaded into a printer to create custom meals for an individual’s diet and nutritional needs.

The 3D printers could end food waste as Quartz reports cartridges would be shelf-stable for up to 30 years.
