Method, system and equipment for automatically generating supporting structure supporting 3D printing forming

The invention discloses a method, a system and equipment for automatically generating a support structure supporting 3D printing forming, and relates to the field of 3D printing, the method comprises the following steps: generating a plurality of vertical planes according to fixed intervals, respectively intersecting the vertical planes with a first patch model and a second patch model to obtain a plurality of first and second intersecting contour lines, the contour points of the first intersecting contour line vertically and downwards intersect with the second intersecting contour line, the closest intersection point below the contour points is selected, a group of corresponding points corresponding to the first intersecting contour line is obtained, and whether the lower intersection points are on the second intersecting contour line with the same serial number or not is detected between the front and back two-by-two corresponding intersection points in the group; and constructing a triangular patch of the
