▎ 摘　　要

NOVELTY - Thermally conductive polylactic acid three dimensional printing material comprises 30-90 pts. wt. polylactic acid, 10-25 pts. wt. graphene oxide, 0.5-3 pts. wt. antioxidant, 3-7 pts. wt. dispersant and 0.1-1 pts. wt. nucleating agent, where the molecular weight of the polylactic acid is 40000-100000. USE - The material is useful in the field of electrical and electronic, industrial model or circuit board (claimed). ADVANTAGE - The material has low-density, thermal conductivity and electrical conductivity; and meets requirement for high-thermal conductivity, conductive, low specific gravity FDM consumables. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the material, comprising drying raw materials, mixing, adding to single-screw extruder, extruding and granulating.
