Cooking devices that incorporate three-dimensional (3D) printers, lasers, or other software-driven processes may soon replace conventional cooking appliances such as ovens, stovetops, and microwaves. But will people want to use a 3D printer to calibrate the exact micro and macronutrients they need to stay healthy? Will 3D food printing improve the ways we nourish ourselves? Researchers from the Columbia University School of Engineering and Applied Science believe that it will and, 3D food printing for some people, could mean better control and tailoring of nutrition. Laser cooking and 3D food printing could allow chefs to localise flavors and textures on a millimeter scale to create new food experiences. People with dietary restrictions, parents of young children, nursing home dieticians, and athletes alike could find these personalised techniques very useful and convenient in planning meals.
