Description

A kind of production method that customization foot steps on component
Technical field
The present invention relates to feet to step on component technology, and in particular to a kind of production method that customization foot steps on component.
Background technique
3D printing is a kind of current rapid shaping technique being widely used, and moulding process principle is: initially setting up mesh The electronic 3-D model for marking part, then carries out hierarchy slicing processing for threedimensional model with software, obtains each machined layer The data information in face carries out lamination increasing material manufacturing according to slice section information, completes the system of target processing under the control of the computer It makes.The advantage of 3D printing is not limited by part shape complexity, does not need any moulds of industrial equipment, and speed is fast, effect Rate is high, can be realized the automated manufacturing of free shape entity, by more and more extensive attention.
Freely manufacturing for various shape entity can be fast implemented since 3D printing is not required to any moulds of industrial equipment, is being criticized In terms of the personalized customization product of quantization, especially there is the unrivaled advantage of conventionally manufactured mode.
In the relevant manufacturing field of shoes industry, various customization shoes continuously emerge in recent years, customize sole/shoes Pad, especially in sport footwear field, also no sooner has one fallen than another steps into the breach for major shoe industry company into the field, for example, Nike (NIKE), Ah Di Dasi company (ADIDAS), Reebok company (REEBOK), An Dema company (UnderArmour) and domestic Pi Ke company (PEAK), Li-Ning Company (LINING).But personalized customization foot steps on component (i.e. sole, insole), at present in market penetration rate side Face is relatively low, and reason has two aspects, one is the high expensive of personalized customization, terminal sale price is just higher；The second is The period of personalized customization is long, and the time that consumer waits is long.
Summary of the invention
The purpose of the invention is to overcome above the shortcomings of the prior art, provides a kind of customization foot and step on component Production method.The production method that this customization foot steps on component can shorten the time of customization, also reduce cost, while ensure that foot is stepped on The performance and comfort of component.
The purpose of the present invention is realized by the following technical solution: the production method that this customization foot steps on component, and customization foot is stepped on Component includes that foot made of main element and 3D printing steps on part, wherein production method the following steps are included:
