Embodiment 1

[0049] Embodiment 1 (flat foot children)

[0050] A personalized custom 3D insole and a manufacturing method thereof, comprising:

[0051] (1) First let a child with flat feet stand on one foot, bend the other lower limb to lift up, lower the calf vertically, use a slightly harder plate to keep the sole of the foot up horizontally, and prepare the mobile phone camera to be located at five angles on the front and slope of the child's sole , each time the plate is opened to take a quick photo; enter the child's weight G (kg), foot length L (mm) and width W (mm) through the software, collect basic data on the sole of the foot, and analyze the data to establish a three-dimensional foot model;

[0052] Divide the sole of the foot into 11 regions: T1 first phalanx, Ta second to fifth phalanx, M1 first metatarsal, M2 second metatarsal, M3 third metatarsal, M4 fourth metatarsal, M5 fifth metatarsal, MFI foot arch Medial, MFO outer arch, HI heel inner, HO heel outer; perform reference...

Embodiment 2

[0063] Embodiment 2 (fall-proof old man)

[0064] A personalized custom 3D insole and a manufacturing method thereof, comprising:

[0065] (1) First let an old man stand on one foot, bend the other lower limb to lift up, lower the lower leg vertically, use a slightly harder plate to keep the sole of the foot up horizontally, and prepare the mobile phone camera to be located at five angles on the front and slope of the sole of the foot. Quickly take pictures by pulling out the plate once; enter the old man's weight G (kg), foot length L (mm) and width W (mm) through the software, and analyze the data to establish a three-dimensional foot model;

[0066] Divide the sole of the foot into 11 regions: T1 first phalanx, Ta second to fifth phalanx, M1 first metatarsal, M2 second metatarsal, M3 third metatarsal, M4 fourth metatarsal, M5 fifth metatarsal, MFI foot arch Medial, MFO lateral arch, HI medial heel, HO lateral heel. Carry out reference calculation for each district accordi...

Abstract

The invention belongs to the technical field of insole making and discloses an individualized 3D printed insole and a making method thereof. The method comprises the following steps: (1) obtaining basis data of foot size to establish a foot three-dimensional model; partitioning the sole, analyzing the health condition of the foot according to relevant data of each zone of the sole, and determining the three-dimensional curve of each zone and the three-dimensional curve of the foot; (2) dividing the insole into a bottom layer, a middle layer and an upper layer, wherein the bottom layer is made from thermoplastic polymer hard material, the middle layer is made from modified polyurethane elastomer, and the top layer is made from nylon plant fiber composite material; (3) deriving an insole structure model fitting the foot according to the foot three-dimensional model, relevant data of each zone of the sole, the health condition of the foot, and individual requirements; (4) carrying out 3D printing on the insole. The method disclosed by the invention is economical, convenient and efficient, individualized adjustment on the performance of local materials can be carried out for different zones of the sole, and insoles capable of meeting the requirements of different people can be produced.

Description

technical field [0001] The invention belongs to the technical field of insole production, and in particular relates to a personalized 3D printed insole and a production method thereof. Background technique [0002] 3D printing technology is a rapid prototyping and additive manufacturing technology. It automatically prints a 3D solid structure that is completely consistent with the model layer by layer by superimposing and stacking manufacturing processes based on 3D model data. It combines digital modeling, mechanical control, information engineering, The cutting-edge technology in the field of materials science and other fields is known as the core technology of the "fourth industrial revolution". Due to the characteristics of high processing precision, economical and convenient manufacturing, and various materials, it can manufacture any complex structure, and has been widely used in many personalized product creation fields. [0003] The human foot is composed of arches,...
