Mask printing route generating method for force line distribution

The invention discloses a mask printing route generating method for force line distribution. A manifold mesh model of a part is loaded, and the direction and height of layered sections manufactured through additives are determined; a three-dimensional rectangular coordinate system is set up, aixe align bounding boxes are constructed, and the aixe align bounding boxes are parallel to the printing plane; section layering treatment is carried out, and the height proportion, the section connected domain contour and aixe align bounding box of each layer of layered section are obtained; the sectionconnected domain contours are subjected to rasterizing treatment, and the mask pattern of each layered section is dynamically constructed; the mask characteristic lines of the mask patterns are extracted through Hough transformation; thus, areas are divided, and the scanning angles of all the areas and the framework line and scanning density of the manifold mesh model are determined; and the parallel scanning lines of the
