The present invention relates to the technical field of printing. Disclosed are a 3D printing method and system. The method comprises: converting a to-be-printed three-dimensional model recording material information, into two-dimensional polygons on multiple layers, and making each two-dimensional polygon comprise the material information; dividing a two-dimensional polygon comprising various types of material information on each layer into a plurality of two-dimensional sub-polygons, and making each two-dimensional sub-polygon only comprise one type of material information; and controlling multiple spray nozzles to print the two-dimensional sub-polygons one by one by layer according to the material information comprised in each two-dimensional sub-polygon. Also disclosed is a 3D printing system. In the present invention, multi-spray- nozzle and multi-material 3D printing is implemented. |
