A mechanical engineer (awesomely) named Anjan Contractor has won a NASA grant to prototype a 3D printer for food -- specifically pizza. It will lay down layers of food and flavor powder and melt them together; the powders are room-temperature stable for long periods and can be made from relatively abundant, sustainable foodstocks like insects and soylent green. He prototyped the concept with the 3D chocolate printer in the video above, and he holds out hope that food-printing could solve world hunger by allowing billions to feast on low-wastage, low-energy-input, low-carbon-footprint foods that are printed to order.
Contractor's printer is RepRap based, and is open source hardware; he promises to keep the plans open and free.
I suspect that there's a lot of nutritional subtleties lost when you turn food into processed elements that are recombined (in the same way that beta-carotene in carrots is reliably shown to have health benefits, while beta-carotene supplements are far more questionable). But as a form of food processing, it certainly is exciting!
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. Contractor’s “pizza printer” is still at the conceptual stage, and he will begin building it within two weeks. It works by first “printing” a layer of dough, which is baked at the same time it’s printed, by a heated plate at the bottom of the printer. Then it lays down a tomato base, “which is also stored in a powdered form, and then mixed with water and oil,” says Contractor.
Finally, the pizza is topped with the delicious-sounding “protein layer,” which could come from any source, including animals, milk or plants.

John Deere is notorious for arguing that farmers who buy its tractors actually “license” them because Deere still owns the copyright to the tractors’ software; in 2015, the US Copyright Office affirmed that farmers were allowed to jailbreak their tractors to effect repairs and modifications.

When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
