3D printing with meat and sugar is fine, but where's the food for the more health conscious futurists among us? Cambridge based design studio Dovetailed might have the solution, after developing hardware that can print fruit, or at least, a close approximation. Droplets of fruit juice and alginic acid are dropped into a bath of calcium chloride, which causes them to form a gelatinous ball. By repeating this action several times, molecular gastronomists chefs are able to build them up into structures that kinda look like berries. We're not sure if we'd be able to switch this out for our regular apple-per-day, but hell, it's better than a diet entirely comprised of burgers and delicately-crafted candy.
