It is true. You can print food now.
NASA paid to develop a prototype 3D printer for food, so astronauts may one day enjoy 3D-printed pizza on Mars. NASA hopes the technology may one day be used to feed astronauts on longer space missions, such as the roughly 520 days required for a manned flight to Mars. Manned missions to destinations deeper in the solar system would require food that can last an even longer amount of time.
Dividing the various components of food in powder cartridges would theoretically enable users to mix them together, like the ingredients in normal recipes, to create a diverse array of nutritious meals.
To prove his idea works, Contractor printed chocolate. Now, he’s aiming to build a more advanced prototype to print a pizza, according to Quartz.
The system will start by “printing” a sheet of dough, followed by a layer of tomato “sauce,” which will consist of the powder mixed with water and oil. Instead of traditional toppings, the 3D-printed pizza will be finished off with a layer of protein, which can be derived from animals, milk or plants, Contractor told Quartz.
While NASA sees applications for 3D printers on future manned space missions, Contractor said his food synthesizer could also be an effective way of addressing the problem of food shortages from rapid population growth.
I guess 3D printed food is not only useful for the astronauts in space, it is useful for the ordinary people during food shortages on earth and probably it is the ultimate food for new busy and lazy future generation.
3D printed food will definitely be nutritious and healthy. But what about taste? Will the printer be able to print taste?
