3D food printing allows for personalized and customized food production. Key benefits include personalized nutrition, flavors, and textures based on individual preferences. Food can be printed at home, in restaurants, grocery stores, or by food companies. Current food printers use techniques like fused deposition modeling, binder jetting, and stereolithography to print foods. Examples of early printed foods include decorated cakes and desserts. Ongoing research aims to develop methods for printing new textures, fully personalized meals, and faster production. The future of 3D food printing may include on-demand personalized meals produced via integrated food printers, software, and ingredient systems.
