Three-dimensional printing is changing the way the Army treats injuries and builds bombs, and now the technology is poised to revolutionize how soldiers are fed. 3D printing will allow the Army to print food on demand, from pasta to pizza, and tailor its nutritional content to an individual soldier’s needs. Feeding thousands of soldiers in the wilderness of a far-flung battlefield has never been an easy task. The food served to Army personnel needs to be unspoiled, nutritious, and reasonably tasty. For decades, soldiers have dined on Army-supplied Meals, Ready to Eat, but MREs are usually pretty unappetizing and limited to 24 options like “beef taco filling” served in a tinfoil bag. You couldn’t even get a pizza until last year when Army researchers developed a groundbreaking pizza that stays fresh for three years.
