At present, the construction method of 3D printing wall is generally to use large-scale building 3D printer to directly print the wall structure of the house when the site space permits, and pour concrete or cement mortar inside the wall structure after 3D printing is completed. It is understandable that the length, width and height of common houses are more than 2 meters respectively, which requires the movement stroke of the large-scale construction 3D printer in the three directions of the length, width and height of the house to be more than 2 meters. The working process occupies a very large area and space, and has high requirements for the working environment. Therefore, the current 3D printed walls can only be built when there is enough space in the environment, which limits the application of 3D printed walls.

In order to solve the above problems, as shown in FIG. 1 , the present embodiment provides a 3D printed wall body, the 3D printed wall body includes a plurality of stacked components 100, and a plurality of stacked components 100 are stacked on top of each other, and each stacked component 100 includes A plurality of stacking modules 110 are connected end to end.
