The invention discloses a light-curing 3D printing method based on multiple light source modules. The method comprises the following steps: controlling a light-curing 3D printer to acquire a pluralityof slice images and a plurality of offsets of multiple layers of a corresponding 3D object; selecting a slice image of one of the layers; adjusting the illumination range of the plurality of light source modules according to the offsets of the same layer so as to allow the illumination ranges of the plurality of light source modules to be not overlapped in a horizontal axial direction after adjustment; based on the selected slice image, controlling the plurality of light source modules to perform illumination according to the adjusted illumination ranges; and repeating the above steps to generate a 3D solid model. The light-curing 3D printing method of the invention can effectively realize large-size light-curing 3D printing and can generate the 3D solid model without obvious bonding lines. 本发明公开种多光源模块的光固化3D打印方法，
