Manufacturing method of multi-structure 3D printing orthopedic insole

Abstract

The invention discloses a manufacturing method of a multi-structure 3D printing orthopedic insole. The manufacturing method comprises the following steps that three-dimensional data of a foot of a person is obtained, a three-dimensional model of the foot is established, and a three-dimensional curved surface of the sole is determined; a foot shape is determined according to the obtained related data, the sole is partitioned, and the insole is correspondingly divided into manufacturing areas of the same number; according to the pressure data and the foot shape, manufacturing materials, manufacturing structures and densities used in the corresponding manufacturing areas in the insole are determined; an insole structure model is generated according to the three-dimensional model of the foot and the three-dimensional curved surface of the sole; and the insole structure model is guided into a 3D printer, and the insole is printed according to the insole structure model and the manufacturing materials, the manufacturing structures and the densities used in all the manufacturing areas of the insole and according to the sequence of all the manufacturing areas. According to the foot shape of each person, the foot shapes of different symptoms and the pressure distribution conditions, the local material performance of different areas of the insole is adjusted in a personalized mode, and the insole can adapt to various foot shapes to be customized in a personalized mode.

Description

technical field [0001] The invention relates to the technical field of 3D printing technology and orthopedic insole manufacturing, in particular to a method for manufacturing a multi-structure 3D printed orthopedic insole. Background technique [0002] The foot is an important part of the human body movement system. Foot diseases and injuries have become problems that plague people. Orthotic insoles can effectively treat and prevent the risk of foot diseases and injuries, and have become the main means of physical correction. [0003] Most of the insoles currently on the market are made of molds, but everyone's feet are different, and it is difficult to customize the mold processing for individuals. Existing custom-made insoles mainly contain two modes: traditional plaster model making and computer-aided design and making. The traditional plaster model production is to manually take out the foot model with plaster bandages, turn over the mold and repair it, heat it with hig...

Problems solved by technology

In recent years, with the development of 3D printing technology, many companies and research institutions have gradually carried out 3D printing of insoles. Compared with the processing technology of CNC machine tools, 3D printing technology of insoles is more economical, convenient and efficient. The 3D printing materials of the insole are diversified, and the performance of the produced insole is more personalized. Although there are 3D printed insoles in the prior art, the material and structure of the entire insole are basically the same, and local materials cannot be used for different areas of the sole.
