Abstract: Food 3D printing technology is a future food processing technology with the functions of customizing specific shapes, realizing personalized nutrition and developing new resources. In the meat industry, the application of food 3D printing technology can upgrade the meat processing industry chain by reducing the waste of raw meat, increasing the added value of products, and developing by-products of livestock and poultry. Therefore, this article introduces the reader to the operating principle of food 3D printing technology, overviews recent studies on the printability of meat materials. Meanwhile, it presents an outlook on the application of food 3D printing technology in meat production and processing. This review is expected to provide a scientific and theoretical basis for the application of food 3D printing technology in the field of meat products.
