Detailed Description

To explain technical contents, structural features, achieved objects and effects of the present invention in detail, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. Moreover, the various exemplary embodiments may be different, but are not necessarily exclusive. For example, the particular shapes, configurations and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

In the present application, unless expressly stated or limited otherwise, the term "coupled" is to be construed broadly, e.g., "coupled" may be a fixed connection, a removable connection, or an integral part; may be directly connected or indirectly connected through an intermediate.

Fig. 1 shows the 3D printed shoe provided by the present invention, which is worn by a user to protect the foot. This 3D prints shoes including being located the bottom and being used for supporting sole 1 of user's foot, being located the vamp 2 of 1 upside of sole, being located top and opening welt 3 up and arranging in anterior tip 4, sole 1, vamp 2, welt 3 and tip 4 are made and integrated into one piece by 3D printing.

With reference to fig. 2 and 4, the sole 1 is formed by three-dimensionally interconnecting a plurality of first hollow unit cells (not shown), so that the sole 1 is elastic. The first unit grids have a face-centered cubic structure, and each first unit grid is communicated with air flow so as to improve the air permeability of the sole 1. In addition, because this sole 1 is for having certain thickness and loose porous structure, it can provide better shock attenuation buffering effect and sweat-absorbing effect for user's foot, is particularly suitable for the user that the heavy or foot sweat gland teaches well.

The sole 1 has a front sole portion 11 and a rear heel portion 12 which are arranged in a front-rear direction and are respectively suitable for supporting a front sole and a rear heel of a foot of a human body. The heel portion 12 is configured to have a height of 30-60mm and higher than the forefoot portion 11 to follow the contour of the sole of a human foot. When the foot of a human body applies pressure to the sole 1, the sole 1 can generate adaptive deformation and always fit the sole of the human body, and the arch collapse can be prevented or slowed down to a certain extent.

Furthermore, a number plate area 13 is further arranged on the ground of the sole 1, and the number plate area 13 can display information such as corresponding number, brand name and the like.

Referring to fig. 1-2, the shoe upper 2 is formed by two-dimensionally interconnecting a plurality of second hollow unit grids (not shown), which are also air-permeable. The upper 2 is configured to conform to the contours of the upper surface of a human foot, wherein the mesh of the second grid cell at the instep of the human foot is directly larger than the mesh diameter of the second grid cell at other locations to enhance breathability and further enhance comfort for the user when worn.

Referring to fig. 3, the collar 3 is a solid elastic rib structure extending circumferentially and configured to fit the wave shape of the ankle of the user. The collar 3 includes a pair of lips 31 at the front and a gap (not shown) defined by the pair of lips 31, which can expand the deformable range of the collar 3 to facilitate the user to put on and take off the 3D printed shoe.

The toe cap 4 is located on the upper side of the sole 1 and on the front side of the vamp 2, and is formed by two-dimensional interconnection of a plurality of third unit grids. The mesh diameter of the third unit cell is smaller than that of the second unit cell and the opening ratio at the toe cap 4 (the ratio of the total area of the meshes on the toe cap 4 to the total area of the toe cap 4) is smaller than that of the upper 2 to ensure that the toe cap 4 has sufficient structural strength to protect the toes of the user.

Further, the 3D printing shoe further comprises a circumferentially extending edge portion 5 arranged on the upper side of the sole 1, the edge portion 5 being formed by a plurality of ribs. The vamp 2 and the toe cap 4 are both positioned on the upper side of the edge part 5, and the edge part 5 is simultaneously connected with the sole 1, the vamp 2 and the toe cap 4 so as to prevent the connecting parts of the first unit grid and the second unit grid and the first unit grid and the third unit grid from being broken due to insufficient strength.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
