Three-dimensional food printer

A three-dimensional food printer is composed of a mechanical arm (1), a stepping motor turn plate (2), a food nozzle (3), a conveying belt (4), a baking oven (5), a tray (6) and a computer (7), wherein a designed three-dimensional model of food to be preprinted and a control signal in the computer (7) is output to the mechanical arm (1) and the stepping motor turn plate (2) through a data line, the mechanical arm (1) and the stepping motor turn plate (2) are controlled to cooperatively work according to the layer property of the designed food three-dimensional model, the food nozzle (3) is controlled to print the food sequentially according to the layer, the food is conveyed to the baking oven (5) to be baked through the conveying belt (4) after the food is printed, and manufacture of the food is finished. The three-dimensional food printer has the advantages of being capable of automatically, rapidly, directly and accurately converting the design in the computer into the model, directly finishing the manufacture of the food, and having a wide market prospect.
