3D Printing Approaches

Abstract

Despite 3D food printing being a nascent emerging technology in the food industry, it has a greater potential in fulfilling commercial and consumer needs. 3D printing has been forecasted to be revolutionizing the technology of the future. Various well-known 3D printing technologies are material extrusion, powder bed fusion, binder jetting, material jetting, vat polymerization, sheet lamination, and direct energy deposition. In context with food, not all the printing technologies are suitable for the printing process as food is a complex perishable commodity that often undergoes desired amount of pre- as well as postprocessing operations. Hence, this chapter envisages the major considerations of the food-printing process, material properties, and selectivity of materials that are suitable f
