NASA has given mechanical engineer Anjan Contractor (apparently his real last name) a $125,000 grant to create a unit that will use the molecular technology to create food. According to Quartz, "Pizza is an obvious candidate for 3D printing because it can be printed in distinct layers, so it only requires the print head to extrude one substance at a time." And, yes, that was a glib headline, but the actual goal of the project is pretty impressive:

[Contractor] sees a day when every kitchen has a 3D printer, and the earth’s 12 billion people feed themselves customized, nutritionally-appropriate meals synthesized one layer at a time, from cartridges of powder and oils they buy at the corner grocery store. Contractor’s vision would mean the end of food waste, because the powder his system will use is shelf-stable for up to 30 years, so that each cartridge, whether it contains sugars, complex carbohydrates, protein or some other basic building block, would be fully exhausted before being returned to the store.

The auxiliary benefit of this would be another rather amazing thing: food for prolonged space travel, which is probably also essential to the survival of the human race due to the phenomenon of the human race continuing to barf pollution all over Mother Nature's face all the time. Have a look at this video, in which chocolate is printed. In short, go Anjan Contractor!
