▎ 摘 要
NOVELTY - 3-dimentional printing process is claimed, where the graphene modified thermoplastic polyurethane powder as a substrate and the graphene-modified thermoplastic polyurethane sole or the graphene-modified thermoplastic polyurethane insole is printed by the 3-dimentional printing process according to the designed sole or insole model. USE - The 3-dimentional printing process is useful for a high performance insole (claimed). ADVANTAGE - The method realizes sole-insole under the relatively low temperature of the printing; and has heating energy consumption is 1/3 -1/2 and utilization rate of 100 % and is economical.
