Controllable jetting type food 3D (Three-Dimensional) printing equipment and method

The invention discloses controllable jetting type food 3D (Three-Dimensional) printing equipment and method. The controllable jetting type food 3D printing equipment comprises a space three-dimensional locating device and a discharging device with rotatable nozzles, wherein the space three-dimensional locating device comprises sliding blocks which can freely move in an XY plane and a substrate which can move up and down along a Z direction, a nozzle fixing device is installed on a sliding block by virtue of a rotatable disc, the rotatable disc is provided with the five cylindrical nozzles, the nozzles correspond to different feeding cylinders, and flat mouth nozzles which are slantingly installed is also equipped and can be used for replacing the cylindrical nozzles. The controllable jetting type food 3D printing equipment and method are suitable for 3D printing of arbitrary flowing paste liquid food, can have the arbitrary functions of 2D drawing, 3D stereo-lithography and the like and have the advantages of high efficiency, wide application range, high precision and the like.
