[Anjan 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.
Ubiquitous food synthesizers would also create new ways of producing the basic calories on which we all rely. Since a powder is a powder, the inputs could be anything that contain the right organic molecules. We already know that eating meat is environmentally unsustainable, so why not get all our protein from insects?
Also, CNN reports on how a 3D printer saved the life of an infant with breathing problems:
“We can put together a complete copy of a body part on the 3-D printer within a day,” [Dr. Glenn] Green said. “So we can make something very specific for a patient very quickly.”
Green then took the splint, measuring just a few centimeters long and 8 millimeters wide, and surgically attached it to Kaiba’s collapsed bronchus. It was only moments before he saw the results.
“When the stitches were put in, we started seeing the lung inflate and deflate,” Green said. “It was so fabulous. There were people in the operating room cheering.”
