Manufacturing method for 3D (three-dimensional) printing shoe pad

Abstract

The invention discloses a manufacturing method for a 3D (three-dimensional) printing shoe pad. The manufacturing method comprises the following steps: acquiring foot data in sequence, scanning feet to obtain foot shape dimension data, and obtaining sole pressure data during various daily activities through a pressure test; generating a three-dimensional model by data processing software according to the acquired foot shape dimension value, combining the three-dimensional model with measured pressure value to analyze multi-layer shoe pad plane data, and inputting the multi-layer shoe pad plane data into a 3D printer; respectively sintering various powdered thermoplastic materials and then supplying the sintered various powdered thermoplastic materials to a spray head of the 3D printer; selecting the sintered thermoplastic materials by the 3D printer according to the shoe pad plane data, heating the thermoplastic materials through a spray nozzle of the 3D printer, and then printing corresponding shoe pad layers layer by layer on a shoe pad mould, fusing and depositing the thermoplastic materials on each plane layer to form a shoe pad finished product. According to the manufacturing method disclosed by the invention, the customization of high-quality shoe pads can be realized, complex processes can be eliminated, meanwhile, the raw material consumption is reduced, the production efficiency can be improved effectively, and the cost can be saved greatly.

Description

technical field [0001] The invention relates to the field of insole production, in particular to a method for making a 3D printed insole. Background technique [0002] The insole is a very important part of the shoe. It is a direct pressure-bearing part between the foot and the shoe body. It has the function of dispersing and concentrating the pressure, protecting the safety of the sole of the foot, and largely determines the comfort of people when wearing shoes. For The shape, contour and surface changes of the soles of the human feet, etc., the impact of the insole is very obvious, and the human body needs to wear shoes for activities in daily life, thereby continuously and variablely producing different gaits and sole shapes, so the insole is contacted by the soles of the feet It is very changeable and complex, and most of the current insoles are designed and produced in a flat manner, and have not been optimized for changes in human feet and activity pressure, and have n...

[0002] The insole is a very important part of the shoe. It is a direct pressure-bearing part between the foot and the shoe body. It has the function of dispersing and concentrating the pressure, protecting the safety of the sole of the foot, and largely determines the comfort of people when wearing shoes. For The shape, contour and surface changes of the soles of the human feet, etc., the impact of the insole is very obvious, and the human body needs to wear shoes for activities in daily life, thereby continuously and variablely producing different gaits and sole shapes, so the insole is contacted by the soles of the feet It is very changeable and complex, and most of the current insoles are designed and produced in a flat manner, and have not been optimized for changes in human feet and activity pressure, and have not achieved sufficient results.

[0003] Traditional insoles are mostly made of EVA or other materials. When producing insoles, first make a large piece of the original piece, and then slice it according to the required thickness. It is to paste the required cloth or other materials together, and then go through the hob trimming, trim it into the required thickness and shape, and then put it into the abrasive tool for molding, heating, compression and shaping, so as to make a standard insole. This process is very cumbersome. , Time-consuming, and this is only suitable for mass production of a standardized insole, not suitable for the production of insoles that are individually adapted to different actual usage conditions, and the limitations are very obvious
