Abstract

The invention particularly relates to a trigonometric star cellular system parameterized 3D printing sole pressure distribution sole. A preparation method of the sole mainly comprises the following steps: scanning a foot to obtain a sole pressure distribution diagram; the Rhino software and the Grasshopper plug-in are used for carrying out parameterization on the shoe sole to carry out modeling; creating a triangular star hollow honeycomb system, accurately defining an interference point range according to a maximum pressure area, and adjusting parameters of triangular star honeycomb unit cells; a TPU material is applied; and an FDM 3D printer is adopted for printing. The preparation system comprises a mechanical metamaterial structure system, a parameter design system and a TPU material application and digital manufacturing system. According to the method, customized correction sole design is rapidly and effectively carried out, and a personalized sole is adjusted by simply operating a parameter instruction in grasshopper, so that an excellent plantar pressure distribution requirement is met, the problem of plantar pressure of a human body is solved, and the harm to human health caused by unbalanced feet and force acting on the human body is relieved.

Description

technical field

[0001] The invention belongs to the technical field of 3D printing, and in particular relates to a three-dimensional star honeycomb system parametric 3D printing of soles of soles with pressure distribution. Background technique

[0002] The sole is the footwear component that affects footwear biomechanics, dynamic behavior, etc.; the performance of the shoe can be improved through materials and construction, and a shoe with superior performance can provide comfort and cushioning by redistributing foot pressure for human and foot health Provide protection. In recent years, the lattice (lattin) structure has been one of the most recognized structures in footwear midsole design. FDM, as a popular 3D printing method, has the characteristics of cost-effective, green manufacturing, and applicable to a variety of materials, but , due to poor precision, complex structures such as unsupported lattice structures cannot be printed.

[0003] Therefore, it is necessary...

Embodiment Construction

[0043] The present invention will be described in further detail below with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0044] First, the terms involved in this embodiment are explained:

[0045]Algorithms (Grosshopper algorithms): Parametric design is a design process in which the project itself is written as functions and processes, and the design process is automated by modifying the initial conditions and obtaining the project results through computer calculations. Grasshopper instructions can be opened Plugin window. Grasshopper is a graphical algorithm editor tightly integrated with Rhino's 3D modeling tools. Rhinoceros comes with its own node-based visualization language, Grasshopper, by connecting the programming method of internal battery component efficiency, building a program that follows a set of rules, allowing designers to easily change the visualization operation nodes to quickly execute parametr...
