NOVELTY - 3-Dimensional(3D) printed material comprises 12-15 pts. wt. graphene, 3-6 pts. wt. bamboo powder, 10-15 pts. wt. kaolin, 1.2-1.6 pts. wt. antioxidant, 36-48 pts. wt. Acrylonitrile butadiene styrene (ABS) resin, 6-10 pts. wt. alkoxylated pentaerythritol hexaacrylate, 2-4 pts. wt. paraffin, 4-8 pts. wt. vinyl ether, 4-6 pts. wt. alumina, 3-5 pts. wt. magnesium oxide, 3-4 pts. wt. acetone, 2-3.6 pts. wt. coupling agent, 1-3 pts. wt. fruit tannin, 15-20 pts. wt. potassium feldspar and 5-8 pts. wt. ginkgo. USE - As printed material. ADVANTAGE - The printed material has excellent electrical conductivity, increased mechanical property, liquidity and viscosity, can meet the use requirements of people and is wide in application range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the 3D printed material comprising (i) soaking ginkgo in 65-75 %mass ethanol solution for 60-80 minutes, filtering out, drying, crushing, mixing and leaching the crushed ginkgo and sodium hydroxide aqueous solution to obtain a ginkgo extract, performing centrifugal separation on the ginkgo extract, and taking the supernatant on the upper layer to obtain ginkgo extract, (ii) adding and mixing graphene, ginkgo extract, ABS resin, alkoxylated pentaerythritol hexaacrylate and potassium feldspar in a ball mill at 50-60 degrees C for 4-6 hours to obtain first mixture, (iii) uniformly mixing the bamboo powder, kaolin, vinyl ether, acetone and fruit tannin, adding 0.4-0.8 times deionized water and stirring to obtain slurry, placing the slurry in a low-temperature plasma processing instrument, treating for 20-30 minutes, adding antioxidant and paraffin to the slurry, and uniformly stirring to obtain a second mixture, and (iv) mixing the first mixture and second mixture, alumina, magnesium oxide and coupling agent in a low-speed mixer, adding to a double-screw extrude and extruding at 200-220 degrees C, where the rotating speed of the screw is 600-750 rpm, and cooling after extrusion.
