3D printing method for binary light-cured 3D printer

The invention discloses a 3D printing method for a binary light-cured 3D printer. The 3D printing method comprises the following steps: controlling the binary light-cured 3D printer to acquire a plurality of gray-scale slice images; mapping the value of each pixel of each gray-scale slice image in a total pixel range to an accumulated value range so as to acquire the printing parameters of each pixel; sequentially selecting one of the plurality of gray-scale slice images; controlling a binary light source module to carry out irradiation according to the printing parameters of each pixel of theselected gray-scale slice image so as to generate a layer of a slice solid model; and repeating the above steps to generate a 3D solid model formed by stacking of a plurality of layers of slice solidmodel. The method of the invention can realize the 3D printing effect of multi-stage light source modules by using the binary light source module, so the fineness of the generated 3D solid model canbe obviously improved. 本发明公
