Feeding the Final Frontier: 3-D Printers Could Make Astronaut Meals
Several decades from now, an astronaut in a Mars colony might feel a bit hungry. Rather than reach for a vacuum-sealed food packet or cook up some simple greenhouse vegetables in a tiny kitchen, the astronaut would visit a microwave-sized box, punch a few settings, and receive a delicious and nutritious meal tailored to his or her exact tastes.
This is the promise of the rapidly maturing field of 3-D food printing, an offshoot of the revolution that uses machines to build bespoke items out of metal, plastic, and even living cells. Sooner than you think, 3-D printed designer meals may be coming to a rocketship, or a restaurant, near you.
