Claim 13:
14. A printing system for printing the support structure according to claim 1, wherein the printing system comprises:
a print head configured to print a layer solid portion using a first material and print a layer non-solid portion using a second material according to support structure layer printing data in a same slice layer, and configured to print a plurality of layer solid portions and a plurality of layer non-solid portions in such a manner that the plurality of layer solid portions forms a solid portion of the support structure and the plurality of layer non-solid portions forms a non-solid portion of the support structure;
wherein a hardness of the first material is different from a hardness of the second material; the solid portion comprises a grid structure, and both inside and outside of each grid unit of the grid structure are filled with the non-solid portion;
a grid density of the grid structure varies within a printing plane,
and/or
an area of a cross-section of a connecting edge of the grid unit varies in a direction perpendicular to the printing plane;
a controller configured to control the print head to perform a printing operation;
the print head is connected to the controller.
