Abstract: The method of manufacturing the insulation member includes manufacturing a 3D printing material using a mixed material in which one or more materials selected from among polycarbonate (PC), polybutylene terephthalate (PBT), acrylonitrile-butadiene-styrene (ABS), polyamide (PA), polyoxymethylene (POM), and polyethylene terephthalate (PET), one or more fillers selected from among TiO2, SiO2, and AlO3, and a curing agent are mixed, and which contains different amounts of the fillers at predetermined intervals in a longitudinal direction, and sequentially stacking the manufactured 3D printing material using a 3D printer to thus manufacture a target insulation member so that the mixed material containing different amounts of the fillers at predetermined intervals in a longitudinal direction of the insulation member is sequentially stacked.
