Computer simulating method of 3D printing process based on networked particles

The invention discloses a computer simulating method of a 3D printing process based on networked particles. The read-in networked data is the same as initial required CAD file data of a 3D printed piece, and the initial data starts from a CAD file in text simulation. By means of a method oriented to objects, all factors of a printing system in the printing process of a 3D printing machine are objectified, so comprehensive virtual printing is achieved, the three aims of obtaining grid nodes, node sequence objects and codes of the node sequence objects, obtaining grid units, unit set objects and codes of the unit set objects, and obtaining printing step size objects, printing line objects and codes of the printing line objects are achieved, a printing track model is established, a transverse back-forth scanning mode printing track algorithm is designed to generate a printing track, through the read-in of the networked data and the assembly of printing body data, the stacking process based on the grid units is d
