3D printed food
This cake with a topping made of sugar was printed by 3D Systems, which is also developing technology for printing chocolate candies. But 3D printing of food doesn’t stop with sweets.
Intellectual Ventures Laboratory in Bellevue, Wash., is one of many research groups developing systems designed to print everything from steak and hot dogs to rice. Equipped with toner-type cartridges that hold pulverized freeze-dried foods, the meal printers would add water and minuscule amounts of healthy ingredients, such as green vegetables, while extruding the freeze-dried material to create edible foodstuffs that look like the meals we eat every day.
