ABSTRACT
Three-dimensional (3D) printing is a process that creates 3D objects from a virtual model, usually designed through computer aided design (CAD) software. The principle of a 3D printer is analogous to that of a regular office printer, to which has been added a third dimension, giving the ability to print three-dimensional objects from a range of materials. 3D printing has rapidly become a disruptive technology in many industrial areas around the globe. 3D printing has progressively appeared in the realm of food manufacture. 3D food printing has been seen to be used in a variety of applications, ranging from home-cooking with families to professional chefs at Michelin star restaurants. Currently, 3D food printing has been established in food areas as diverse as the military, meals for the elderly, confectionery and food designed for space missions.
