• In the last few years, 3D printing has really taken off in the food industry. There have been several reports of even NASA 3D printing food (where the ‘D’ stands for ‘dining’) including a pizza. While this might seem like it is straight out of a sci-fi movie, edible 3D printing is becoming more popular with both the food industry and consumers. Most food 3D printers use extrusion technology that engages paste-type ingredients. Some of the most commonly printed foods are chocolate, pancakes and pizzas.
