Abstract: The present invention relates to a 3D model dividing and layering control system and method which, in a method for forming a three-dimensional shape by spraying a layering material having a predetermined viscosity or more, minimize stringing which occurs during repeated spraying, through a nozzle, of a layering material and stopping spraying, can improve the layering rate of a three-dimensional shape, can also form the desired three-dimensional shape by layering, inside a specific material, a material having a viscosity different from that of the specific material, can readily and simultaneously form a three-dimensional shape inside each of a plurality of containers, and do not require separate washing of a nozzle and replacing of a layering material, and thus the present invention is suitable for a mass production process.
