Description

Technical Field

[0001] The utility model belongs to the technical field of insole structures, and in particular relates to a 3D printed insole. Background Art

[0002] The operation process of 3D printing insoles is similar to that of traditional 3D printing, including designing insoles, selecting materials, printing insoles, post-processing and other steps. When designing insoles, it is necessary to model and design according to the shape of the foot and the insole, select suitable materials, and then print the designed insoles. After printing, post-processing is required, such as cutting, polishing, shaping, etc., to obtain the final insole product. Compared with traditional manufacturing methods, 3D printing insoles have the advantages of short production cycle and low cost.

[0003] However, the structure of 3D printed insoles in the prior art is mostly the same as that of mold-made insoles. The 3D printed insoles on the market have some disadvantages in terms of wearing and use:

[0004] 1. Poor comfort performance: The comfort of 3D printed insoles in the prior art is affected by factors such as material hardness and structural design, which makes the insoles in the prior art unsatisfactory in terms of comfort;

[0005] 2. The massage effect of the massage insole is not good, and the massage insole is used independently from the ordinary insole, which is not convenient to replace anytime and anywhere.

[0006] Therefore, a new type of 3D printed insole is needed to overcome the above shortcomings and improve the applicability, wear resistance and comfort of the insole. Utility Model Content

[0007] The purpose of the utility model is to provide a 3D printed insole to solve the problems existing in the prior art.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is a 3D printed insole, including an insole main body, wherein a plurality of vertical warps are arranged in the insole main body, a plurality of horizontal wefts are arranged on the back of the insole main body, a plurality of wefts are arranged on the front of the insole main body, the number of wefts on the back of the insole main body is less than the number of wefts on the front of the insole main body, the warps and wefts are staggered to form large gaps on the back of the insole, the warps and wefts are staggered to form small gaps on the front of the insole, the gap between the warps and wefts of the small gaps is 0.6-1mm, so as to achieve support and breathability effects, the warps and wefts of different densities are staggered to form large gaps on the back of the insole, the gap between the warps and wefts of the large gaps is 3-8mm, the large gaps make the elasticity of the insole deform under different forces, so as to achieve adaptive massage of different forces, the front side of the insole main body is provided with a sole, the back side of the insole main body is provided with a heel, and the thickness of the heel is greater than the thickness of the sole.

[0009] Preferably, the thickness of the insole body is 0.6-4 mm.

[0010] Preferably, the insole body is made of TPU material.

[0011] Preferably, the material of the warp and weft is high-elastic soft TPU with a Shore A of 60 to 80.

[0012] Preferably, the number of the weft layer and the warp layer on the back side of the insole body is at least three.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] The design of this 3D printed insole takes ergonomics and comfort into consideration. Through structural design and material selection, the thickness, softness, massage effect and other aspects of the insole are optimized. The longitude and latitude lines and gap design of the insole give the insole a three-dimensional sense and massage effect, and can better adapt to the shape of the sole and instep, providing better comfort and massage effect. The use of elastomeric materials such as TPU has the advantages of softness, wear resistance, and impact resistance, and is suitable for the personalized customization of artificial wearable products. The insole has a certain thickness, but maintains its softness, and is suitable for long-term wear. The insole massages the sole of the foot on one side, which can relieve fatigue and discomfort of the sole of the foot. This design is suitable for use in sports shoes, providing good support and massage effects, and helping to relieve fatigue after exercise. This design is suitable for use in health shoes, providing good comfort and massage The effect is helpful to promote the blood circulation and health care of the feet. The design is also suitable for special-purpose insoles, such as the elderly, pregnant women, patients with foot diseases and other people who need special insoles. The use of elastomeric materials such as TPU has high wear resistance and can withstand the friction and wear of the insoles during use. Secondly, the large gap design on the back of the insole enables the TPU warp and weft lines to form elastic convex points of different heights after being compressed by the pressure of human body weight, and adaptively realize different strengths of massage and compression on the bottom of the sole according to the force conditions, thereby improving the use effect of dynamic massage when walking. In addition, the sole of the foot on the front side and the heel design on the back side of the insole can better adapt to the shape of the foot, and at the same time increase the space for elastic deformation and massage strength according to different forces, provide better comfort, and further improve the life of the insole.

[0015] Therefore, this 3D printed insole not only has comfort and massage effects, can provide good comfort and massage effects, but also has high wear resistance, can be used for a long time without being easily damaged, is suitable for use in footwear products for different purposes and people, and brings more convenience to foot wearing.
