[0019] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0020] Figure 1The crystal-type integrated shoe 100 provided by the first embodiment of the present invention is shown. The crystal-type integrated shoe 100 includes a shoe upper 110, a shoe sole 120 and an adhesive layer 130. The shoe upper 110 and the shoe sole 120 are connected together by an adhesive layer. The adhesive layer 130 is a solid structure.

[0021] Combined View Figure 2 The upper surface 110 includes a first lattice region 112, a second lattice region 114 and a third lattice region 116. The first lattice region 112 includes a rear upper surface. The second lattice region 114 includes a middle upper surface and a portion of a front upper surface. The third lattice region 116 includes a tongue and another portion of a front upper surface. The sole 120 includes a fourth lattice region 122.

[0022] The first lattice region 112 includes a first lattice structure. The first lattice structure is an isotropic structure, has high tensile strength in all directions, and is not easily damaged. Therefore, the average strength of the back upper surface including the first lattice structure is high, and can provide good support for the upper surface 110, thereby locking the heel. In this embodiment, the first lattice structure is a six-pointed star structure. In other embodiments, the first lattice structure can also be other isotropic structures.

[0023] The second lattice region 114 includes a second lattice structure. The second lattice structure is an anisotropic structure, and its strength in the vertical direction is greater than its strength in the horizontal direction, and its ductility in the horizontal direction is higher than its ductility in the vertical direction. Therefore, the average strength of the middle upper surface and a part of the front upper surface including the second lattice structure is medium, which can provide sufficient lateral protection, protect the instep and allow a certain degree of mobility, thereby reducing the pressure on the instep. In this embodiment, the second lattice structure is a triangular and diamond mixed weaving structure. In other embodiments, the second lattice structure can also be other anisotropic structures.

[0024] The third lattice region 116 includes a third lattice structure. The third lattice structure is an anisotropic structure, and its strength in the direction of the long axis of the shoe is higher than its strength in the direction of the wide axis of the shoe, and its ductility in the direction of the wide axis of the shoe is higher than its ductility in the direction of the long axis of the shoe. Therefore, the tongue and another part of the upper surface including the third lattice structure have low average strength, good tensile properties, fit the foot shape, and facilitate the wearer's wearing and taking off operations. In this embodiment, the third lattice structure is a tensile expansion structure. In other embodiments, the third lattice structure can also be other anisotropic structures.

[0025] The fourth lattice region 122 includes a fourth lattice structure. The fourth lattice structure is a polyhedral structure with a moderate structure density, which can ensure that the sole 120 has a suitable weight and excellent resilience. Figure 3As shown, the fourth lattice structure adopts a hexagonal truncated polyhedron structure based on Archimedean bodies. In other embodiments, the fourth lattice structure can also be other polyhedron structures. In addition, the front and rear soles of the sole 120 can adopt different lattice structures, different lattice densities, or different lattice rod diameters, so as to obtain different rebound forces and support performances of the front and rear soles.

[0026] The crystal-shaped integrated shoes provided in the embodiment of the present invention are made by 3D printing technology. The 3D printing technology that can be used in the specific embodiment of the present invention is selective laser sintering (SLS). Selective laser sintering (SLS) mainly uses an infrared laser as an energy source to shape the powder material. In actual production, the first step is to preheat the powder material; when the temperature of the powder material is raised to slightly below its melting point, the second step is to perform a flattening treatment on the powder material by using a scraping stick; the third step is to selectively sinter the flattened powder material using an infrared laser beam under computer control, wherein the selective sintering is mainly performed according to the layered cross-sectional information provided by the computer, and in practice, the sintering operation of the lower layer is generally performed after the upper layer is sintered; the fourth step is to remove the excess powder after all the powder layers are sintered, thereby completing the crystal-shaped integrated shoes made by 3D printing technology. The finished product. In addition, in an embodiment of the present invention, the 3D printing material of the crystal-shaped integrated shoes uses thermoplastic polyurethane resin (TPU) powder. Thermoplastic polyurethane resin (TPU) is a copolymer composed of hard segment and soft segment materials, which has high tensile properties and wear resistance, as well as excellent elasticity and biocompatibility.

[0027] In other embodiments, the 3D printing technology of the crystal-shaped integrated shoe can also use digital light processing (DLP). Digital light processing (DLP) mainly performs digital processing on the image signal, and then uses a high-resolution digital light processor (DLP) projector to photocuring the liquid photopolymer layer by layer according to the data information to complete the crystal-shaped integrated shoe finished product made by 3D printing technology. As for the 3D printing material of the crystal-shaped integrated shoe, polyurethane (PU) photocurable resin material can also be used. Polyurethane (PU) is a polymer with a repeating structural unit of a carbamate segment made by the reaction of isocyanate and polyol, which also has high tensile properties and wear resistance, as well as excellent elasticity and biocompatibility.

[0028] The upper surface 110 of the crystal-patterned integrated shoe 100 provided by the present invention adopts a first lattice region 1112 with an isotropic structure and a second lattice region 114 with an anisotropic structure, so that the crystal-patterned integrated shoe has a multifunctional regional structure while realizing an integrated structure, providing the wearer with a more comfortable wearing experience.

[0029] Although the description and illustration of the relevant embodiments of the present invention have been given, it should be understood by those skilled in the art that the description and illustration of these embodiments do not constitute a limitation on the scope of the present invention, and the present invention may be transformed in various forms and details without exceeding the concept and scope of the present invention. Therefore, the scope of the present disclosure is not limited to the above embodiments, but should be determined by the claims and the equivalents of the claims.
