Design method and manufacturing method of photocuring multi-material 3D printing model based on capillary action

The invention discloses a design method and a manufacturing method of a photocuring multi-material 3D printing model based on capillary action, and relates to the technical field of 3D printing, and the design method comprises the following steps: S1, partitioning according to different material distribution of different parts of a pre-printing model, and dividing the pre-printing model into a main body material region and a plurality of auxiliary material regions; s2, the structure of each auxiliary material area is adjusted; and S3, according to the material proportion needed by each auxiliary material area, the porosity of the frame structure is determined, and finally the frame structure of the pre-printing model is determined. According to the photo-curing multi-material 3D printing device, the materials of different parts of the pre-printing model are partitioned, and the frame type structure of the auxiliary material area and the solid structure of the main body material area are combined into the tota
