Problems solved by technology

[0017] The popularity of 3D printing technology in industrial products is currently restricted by materials and costs. 3D printing raw materials are currently limited. The commonly used printing materials are only a few materials such as TPU (thermoplastics), nylon, resin, rubber, and metal powder. , plus the current high cost of 3D printing, so in practical applications, 3D printing technology can not completely replace the traditional manufacturing technology

specific Embodiment

[0039] Such as image 3 , Figure 4 As shown, use computer 3D design software to carry out 3D lightweight structure samples or 3D digital modeling of shoe soles, import 3D lightweight structure samples or 3D digital models of shoe soles into a 3D printer to print.

[0040] 3D lightweight structural samples or sole 3D printers use SLS selective laser sintering printers.

[0041] 3D lightweight structural sample or shoe sole 3D printing uses SLS selective laser sintering technology, the printing raw material is TPU powder (or nylon powder), and the laser is used to scan and irradiate the powder layer by layer under the control of the computer to realize the sintering and bonding of TPU powder. Combined, layer upon layer to achieve molding.

[0042]The TPU powder used in the 3D printing sole is a powder with a particle size of 100 microns, and its sintering temperature is 160°. The particle size and molding temperature of the above-mentioned TPU powder are all possible in the p...

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 ...
