The present invention discloses a 3D food printer, which comprises a large hopper in a print head with a cooling system, so as to store and supply a large amount of a food material and print reliably at a high ambient temperature, and an automatic conveying system for printed products, so as to automatically output the food product after printing it, and then proceed with the next one. These features make the printer more effective, easier to operate, and in line with the requirements of food hygiene. The technical solution includes: the 3D food printer comprising a print head for extruding a food material a cooling system for keeping the food material at a low temperature at which the food material does not melt or agglomerate a conveying system for automatically outputting a printed food product a frame for supporting the entire 3D food printer a drive system for driving the 3D food printer to move in the X-, Y- and Z-directions and a control system for controlling the operation of the entire 3D food printer.
