The whole shoe is formed in one time, with fewer processing steps and faster processing speed. The upper layer 1 is formed by a plurality of elastic structures. The elastic structure is composed of a first T-shaped frame 12, a second T-shaped frame 13 and a square frame 11 that are staggered with each other, so that the first T-shaped frame 12 and the second T-shaped frame 13 can produce a small displacement in the square frame 11 while maintaining a buckled state, and will not loosen or crack. In this way, when the upper is subjected to lateral extrusion, that is, after the shoe is inserted, the first T-shaped frame 12 and the second T-shaped frame 13 can produce displacement in the square frame 11 to absorb the extrusion force, and cooperate with the elastic plastic material to produce a larger deformation to absorb the extrusion force and generate elastic force, so that after the foot is inserted, the upper is deformed by the first T-shaped frame 12 and the second T-shaped frame 13 The inner cavity of layer 1 deforms quickly and becomes the shape of the wearer's foot.

The upper triangular frame 211 and the lower triangular frame 213 are both triangular structures.It has high stability. When standing normally, it will not easily produce excessive deformation and tilt. At the same time, when stepped on, the upper triangular frame 211 and the lower triangular frame 213 can shrink inward to squeeze the X-shaped connecting frame 212 to absorb the squeezing force. Since there are more cavities between the X-shaped connecting frame 212 and the upper triangular frame 211 and the lower triangular frame 213, it can obtain a large deformation and contraction ability when impacted, providing strong shock-absorbing and rebound performance, and evenly dispersing the impact when subjected to force.

[0029] The middle section of the mid-bottom layer 2 is provided with an anti-torsion plate 4 formed by 3D printing of high-strength plastic, which is beneficial to improving the anti-torsion performance of the whole mid-bottom layer 2. It can be made of hard TPU or carbon fiber material, which is not easy to twist and cause sprain when worn, and is more stable;

[0030] An inverted L-shaped upper anti-slip bending strip 14 is provided at the end of the first T-shaped frame 12, and an L-shaped lower anti-slip bending strip 15 is provided at the end of the second T-shaped frame 13, which is beneficial to improving the anti-slip performance of the first T-shaped frame 12 and the second T-shaped frame, so that they can be better stuck in the square frame 11, prevent detachment and cracking, and increase the overall strength of the upper layer 1;

[0032] A flat layer 22 formed in one piece by 3D printing is also provided above the treading layer 21. An upper lifting piece 23 formed in one piece by 3D printing is also provided at the edge of the heel of the treading layer 21. A plurality of buffer anti-slip blocks 24 are penetrated and embedded in the flat layer 22. The buffer anti-slip blocks 24 include a capsule 241 penetrated and embedded in the flat layer 22 and a suction tube 245 penetrated and arranged at the center of the capsule 241. The suction tube 245 includes an upper expansion tube 31 and a lower expansion tube 32. A spherical tube 33 is provided between the upper expansion tube 31 and the lower expansion tube 32. The inner wall of the spherical tube 33 is provided with a freely movable and A lightweight ball 34 can be used to seal the bottom end of the upper expansion tube 31. An elastic sheet 35 is provided between the bottom surface of the outer wall of the lightweight ball 34 and the inner wall of the spherical tube 33. An upper fiber layer 243 and a lower fiber layer 242 are provided on the upper and lower surfaces of the inner wall of the capsule 241, respectively. A plurality of elastic fiber strips 244 are provided between the upper fiber layer 243 and the lower fiber layer 242. The capsule 241 is filled with an inert gas. The flat layer 22 is used to improve the touch of the sole when stepping on, further improving the comfort of wearing. The upper lifting sheet 23 is used to improve the stability of the heel. At the same time, during walking or running, the sole of the foot will squeeze the buffer anti-sliding block 24, thereby improving the comfort of wearing. The capsule 241 of the buffer anti-sliding block 24 is squeezed and deformed, and at the same time, an upper fiber layer 243 and a lower fiber layer 242 are arranged in the capsule 241 and connected by an elastic fiber strip 244. Therefore, when the capsule 241 is stepped on, the squeezed part of the capsule 241 can be supported by the elastic fiber strip 244 and is not easily stepped on to the bottom, while the unstepped part of the capsule 241 can be pulled by the elastic fiber strip 244 and will not be excessively expanded and deformed, so that the deformation angle and deformation amount of the capsule 241 are more controllable, providing higher buffering performance during stepping and contraction and improving stability during stepping. At the same time, after stepping on, the suction tube is used to The upper expansion tube 31 of 245 is squeezed, and the air inside it is pressed out from the spherical tube 33, so that the lightweight ball 34 in the spherical tube 33 is squeezed downward, thereby preventing it from closing the upper expansion tube 31, and allowing the gas to pass through the spherical tube 33 and be discharged from the lower expansion tube 32. The lightweight ball 34 is then pushed up by the elastic sheet 35 to reclose the upper expansion tube 31, thereby causing an air pressure difference between the upper expansion tube 31 and the outside world, thereby generating suction, which slightly adsorbs the sole of the foot, allowing a better anti-slip feeling when worn barefoot, thereby making the connection between the sole of the foot and the treading layer more stable, preventing the sole of the foot from slipping, and providing better wearing comfort and heel fit.

[0033] Working principle of the present invention: When the present invention is used, the shapes of the mid-bottom layer 2 and the upper layer 1 of the integrated shoe are preset by a 3D printer, and then the elastic plastic material powder is added into the 3D printer, so that the mid-bottom layer 2 and the upper layer 1 can be quickly formed by the 3D printer, and the whole shoe can be formed at one time, with fewer processing steps and faster processing speed. The upper layer 1 is formed by a plurality of elastic structures, and the elastic structure is composed of a first T-shaped frame 12, a second T-shaped frame 13 and a square frame 11 that are staggered with each other, so that the first T-shaped frame 12 and the second T-shaped frame 13 can produce a small displacement in the square frame 11 while maintaining The buckled state will not be loose or cracked, so that when the upper is subjected to lateral compression, that is, after the shoe is worn, the first T-shaped frame 12 and the second T-shaped frame 13 can be displaced in the square frame 11 to absorb the compression force, and cooperate with the elastic plastic material to produce a larger deformation to absorb the compression force and generate elastic force, so that after the foot is worn, the first T-shaped frame 12 and the second T-shaped frame 13 are deformed to make the inner cavity of the upper layer 1 quickly deform and become the shape of the wearer's foot, and at the same time, the elastic force can make the upper layer 1 fully cover the foot and exert a certain elastic compression on the foot, so that the upper layer 1 can better fit the curve of the foot. The upper layer 1 has multi-directional elasticity and stretchability when exercising, and the gaps between the three are large, which can ensure that the upper layer 1 is fully breathable. At the same time, when wearing, the foot steps down on the mid-bottom layer 2. The 3D printed mid-bottom layer 2 adopts a double tetrahedral symmetrical lattice design of a stepping structure, that is, the stepping structure is formed by the upper triangular frame 211, the lower triangular frame 213 and the X-shaped connecting frame 212. The upper triangular frame 211 and the lower triangular frame 213 are both triangular structures, which have high stability. When standing normally, it will not easily produce excessive deformation and cause side tilting and other phenomena. At the same time, when stepped on, the upper triangular frame 211 and the lower triangular frame 213 can shrink and squeeze the X-shaped connecting frame 212 inward to absorb the squeezing force. Since there are more cavities between the X-shaped connecting frame 212 and the upper triangular frame 211 and the lower triangular frame 213, a large degree of deformation and contraction ability can be obtained when impacted, providing powerful shock-absorbing and rebound performance, and evenly dispersing the impact when subjected to force, and through the X-shaped structure of the connecting frame 212 and the elastic force of the elastic plastic material, the shape is quickly restored after the pressure is released, achieving excellent energy feedback, and there are a large number of cavities inside, with extremely low weight and excellent air permeability.
