[0002] 3D printed hollow shoes are shoes with special structures and designs made using 3D printing technology. These shoes usually use high-performance materials and create complex hollow patterns and structures through precise control of the printing process to achieve lightweight, breathable and fashionable effects.

[0003] 3D printed hollow shoes usually use lightweight, high-strength, wear-resistant and breathable materials. These materials can ensure that the shoes have low weight and good breathability while maintaining good performance. However, the current 3D printed hollow shoes have weak elasticity and are not as good as traditional footwear materials. Utility Model Content

[0004] The purpose of the present invention is to provide a 3D printed hollow shoe in response to the above-mentioned technical problems, which achieves good air permeability while solving the problem of lower elasticity than traditional shoes.

[0006] In this technical solution, the shoe body and the sole are integrally formed using 3D printing technology, which reduces the process and material waste in the manufacturing process, reduces production costs, and improves production efficiency. By setting a hollow cavity in the sole, the breathability of the shoe is increased, so that the feet can remain dry during wear and the possibility of bacterial growth is reduced. A support member and an elastic layer are set in the hollow cavity, and multiple elastic members are embedded in the elastic layer, so that the shoe can produce a certain elastic deformation when under pressure, and under the action of the elastic layer and the elastic members, the elastic ability of the shoe is improved.

[0007] In the above technical solution, further, the support member is in a cross shape, and the support member, the upper base, the lower base and the elastic layer form upper, lower, left and right hollow holes.

[0008] In this technical solution, the cross-shaped support members can more effectively disperse pressure from different directions, thereby enhancing the overall stability and durability of the sole. The cross-shaped support members combined with the elastic layer can provide better elastic feedback when walking, making the shoes more comfortable to wear. The hollow holes formed on the top, bottom, left and right further expand the ventilation area, improve the breathability of the shoes, and help keep the feet dry. The hollow holes are triangular in shape, and have better stability.

[0009] In the above technical solution, further, the elastic member is in an I-shaped shape, and an air outlet is provided in the center of the elastic member.

[0010] In this technical solution, the elastic part of the I-shaped structure can provide stable elasticity and rebound performance, and the air outlet opened in the center further enhances the ventilation effect of the sole, helps to keep the feet dry and reduce discomfort caused by a humid and hot environment.

[0011] In the above technical solution, further, the elastic member is a silicone elastomer.

[0012] In this technical solution, silica gel has excellent elasticity and flexibility, which can provide good cushioning and support when walking, thereby increasing the comfort of the shoes.

[0013] In the above technical solution, further, the elastic layer is a polyester layer.

[0014] In this technical solution, polyester has good elasticity and can recover its original shape after being stretched, providing the shoes with long-lasting elasticity and shape stability.

[0015] In the above technical solution, further, the upper bottom surface is provided with a plurality of air holes.

[0016] In this technical solution, the ventilation holes are at the contact position of the soles of the feet. When the user wears the shoes, they can circulate air and are comfortable and pleasant to wear. They are convenient for three-dimensional ventilation. The ventilation holes are conducive to the discharge of foot sweat, allowing the shoes to dry quickly and keep the feet dry; reducing the weight of the shoes: the ventilation holes can reduce the weight of the shoes and make them more comfortable to wear.

[0017] The beneficial effects of the utility model are:

[0018] 1. A support member and an elastic layer are arranged in the hollow cavity, and a plurality of elastic members are embedded in the elastic layer, so that the shoe can produce a certain elastic deformation when subjected to pressure, and the elastic capacity of the shoe is improved under the action of the elastic layer and the elastic members.

[0019] 2. The cross-shaped supports can more effectively disperse pressure from different directions, thereby enhancing the overall stability and durability of the sole. The cross-shaped supports combined with the elastic layer can provide better elastic feedback when walking, making the shoes more comfortable to wear. The hollow holes formed on the top, bottom, left and right further expand the ventilation area, improve the breathability of the shoes, and help keep the feet dry. The hollow holes are triangular in shape, which has better stability. BRIEF DESCRIPTION OF THE DRAWINGS
