The invention discloses a soft food 3D (three-dimension) printing system. The printing system is characterized by comprising a user operation interface (1), system software (2), an integrated controller (3), a jet molding module (4), a horizontal positioning module (5), a normal direction positioning module (6), a support framework (7), a temperature control module (8), an intelligent cleaning module (9) and a raw material supply module (10). Taking high-strength composite gel as a printing material and combining the temperature control module, the printing system is capable of rapidly shaping soft food. Meanwhile, a touch screen, which is adopted by the user interface in design, can be used for improving user experience and enhancing the enjoyment of a user in design, and the printing system has good market prospect.
