Abstract: As a new type of molding technology, 3D printing is based on the preparation principle of “layered manufacture, layer by layer superposition”. It has the advantages of convenience, flexibility and wide range of application. Food 3D printing technology has given birth to new idea of healthy diet. It can provide unique nutrition meal according to individual requirement. Recently, its application in food processing has been rapidly developed. Especially under the situation of seeking for healthy diets by nowadays society, 3D printing technology has even more shown its superiority in personalized printing. This paper introduced the development status of 3D printing technology; categorized food ingredients available for 3D printing and current printing technologies in food processing; summarized available food printers and their applications in food processing, so as to provide technical guidance for further applications of 3D printing technology in food fabrication.
