3D Printing Breathable Shoe Structure

Abstract

A breathable shoe structure manufactured using 3D printing includes a shoe body. The shoe body is integrally formed using 3D printing, comprising a sole surface, an elastic part of the sole, and a mesh outer layer. The sole surface provides support for the human foot. The elastic part of the sole is located below the sole surface and is formed by a plurality of interlocking ribs in a lattice-like manner, allowing the ribs to elastically support the sole surface. The mesh outer layer extends upward from the outer periphery of the sole surface to form a close fit and cover of the outer side and top of the human foot, and forms a shoe opening. The mesh outer layer also has a plurality of perforations connecting the interior and exterior of the shoe body. Furthermore, the sole surface has a plurality of ventilation holes, allowing the interior of the shoe body to connect to the elastic part of the sole via these ventilation holes. Therefore, the shoe body combines breathability, moisture wicking, quick-drying, elastic support, and a close fit.

Claims

1. A 3D-printed breathable shoe structure, comprising: A shoe body is integrally formed using 3D printing, comprising a sole, an elastic part of the sole, and a mesh outer layer. The sole is used to provide foot support. The elastic part of the sole is located below the sole and is breathable by a plurality of interlocking ribs in a lattice pattern. The ribs provide elastic support for the sole. The mesh outer layer covers the elastic part of the sole and the sole, extending upward from the outer periphery of the sole to form a close fit to the outer side and top of the foot. The mesh outer layer has an opening for the foot to enter and a plurality of perforations that connect the interior and exterior of the shoe body.

2. The 3D-printed breathable shoe structure as described in claim 1, wherein the shoe body is made of an elastic material of polyurethane resin (PU).

3. The 3D-printed breathable shoe structure as described in claim 1, wherein the sole surface is provided with a plurality of ventilation holes, the ventilation holes penetrating the sole surface, and the ventilation holes respectively communicating with the gaps defined by the ribs in the elastic part of the sole, so that the interior of the shoe body is connected to the elastic part of the sole through the ventilation holes.

4. The 3D-printed breathable shoe structure as described in claim 1, wherein the shape of the perforation is any one or a combination of round holes, elliptical holes, irregular rounded corner holes and mesh holes, and the perforation is formed on the mesh outer layer at the instep and sides of the human foot.

5. The 3D-printed breathable shoe structure as described in claim 1, wherein a microporous mesh layer is formed below the elastic portion of the sole, and the microporous mesh layer is exposed relative to the perforation on the bottom side.
