3D printing process for high-performance sole shoe-pad

Abstract

The invention discloses a 3D printing process for a high-performance sole shoe-pad. The 3D printing process adopts graphene modified TPU powder as a base material, and a graphene modified TPU sole ora graphene modified TPU shoe-pad is printed according to a designed sole or shoe-pad model through a 3DP process. The graphene modified TPU powder is adopted as the base material, so that the graphenemodified TPU powder has characteristics of TPU and graphene, and therefore, the effects of resisting wear and slip, deodorizing and sterilizing, being conductive and heat-conductive, and the like canbe simultaneously achieved; graphene modified TPU has very good electrical conductivity, so that development design and production of an intelligent sole shoe-pad can be realized; the graphene modified TPU has very good electrical conductivity, so that development design and production of the intelligent sole shoe-pad can be realized; and 3D printing of the sole shoe-pad can be realized without performing a 3DP process at a relatively low temperature or 3D printing of the sole shoe-pad can be realized by only needing to perform the 3DP process at the relatively low temperature, so that printing efficiency of the 3DP process can be 3-4 times that of an SLS process, heating energy consumption is reduced to be 1 / 3-1 / 2 that of the SLS process, material loss is avoided, a utilization rate is 100%, and cost is reduced.

Description

Technical field: [0001] The invention relates to the technical field of sole and insole production, in particular to a 3D printing process for high-performance sole and insole. Background technique: [0002] The manufacturing materials of traditional insoles include TPU, EVA, rubber, silica gel, etc. The manufacturing process adopts metal mold injection molding, which has a long cycle, high development costs and small sample mass production costs, and cannot be personalized and intelligent. [0003] 3D printing technology has been deeply involved in shoe manufacturing, and the application of 3D printing technology partially solves the above problems, and can also remove mold costs and save valuable time. In the manufacture of outsoles, midsoles and insoles, it is more competitive than traditionally manufactured footwear due to the ability to provide higher performance, more complex textures, unique custom designs, etc. The SLS process is a selective laser sintering technolo...

AI Technical Summary

Problems solved by technology

The SLS process is a selective laser sintering technology. Practical materials include PA12, TPU, etc. It has practical applications in the development and production of shoe soles and insoles. However, due to the high melting point of the material, a high sintering temperature and powder bed working temperature are required. Printing The speed is slow, and the material utilization rate is low, about 50%-70%, which further leads to high cost, which is not conducive to the realization of cost-effective soles and insoles
