Abstract

The invention discloses a 3D printing lightweight lattice structure and a shoe sole adopting the structure. The 3D printing lightweight lattice structure is formed by stacking Weaire-Phelan structuralunits adopting 3D printing. The Weaire-Phelan structural units are regularly stacked in order according to geometric patterns of the Weaire-Phelan structural units, or are stacked after rotating for60 degrees around a triad shaft. The shoe sole is formed in a manner that the Weaire-Phelan structural units adopting 3D printing are cut into the needed shape after being stacked. With the technicalscheme, the sufficient support and comfort are provided while the weight of a shoe is alleviated, with the structural theory of Weaire-Phelan, the economizing optimization of the used materials is realized, in addition, the integral structure looks complicated, while actually, the units have highly repeatability, thus the designing and manufacturing difficulties are reduced, and time and cost arealso saved. Meanwhile, the structure has good mechanical stability and aesthetic property.

Description

technical field

[0001] The invention relates to a shoe sole with a 3D printing structure, in particular to a 3D printing lightweight lattice structure and a shoe sole using the structure. Background technique

[0002] The production of sports shoes is a technology-intensive production chain, which involves multiple links such as design, CAD modeling, wooden mold engraving, mold testing, mold opening, modification, and production. Moreover, manual work cannot be excluded, so the shoemaking industry is known as one of the most difficult industries to automate.

[0003] Most of today's common athletic shoes have soles that contain foam. For example, foams made of ethylene-vinyl acetate (EVA) or polyurethane (PU) provide excellent cushioning against the loads occurring in the sole and are therefore used as the sole between the insole and outsole regions Typical materials for interlayers.

[0004] Shoes are important wearables for people to protect their feet when walking and ...
