NOVELTY - Three dimensional (3D) printing material comprises 15-28 wt.% 1-adamantane formaldehyde modified polylactic acid, 10-20 wt.% toluene, 16-25 wt.% modified aramid pulp, 10-20 wt.% graphene oxide, 2-6 wt.% carbon fiber, 1-6 wt.% nano titanium dioxide, 2-4 wt.% toughener, 1-3 wt.% adhesion promoter, 3-9 wt.% brightener, 1-2 wt.% fluidity modifier, 2-3 wt.% antioxidant, and 2-9 wt.% aluminum powder. USE - Three dimensional printing material for preparing molded product. ADVANTAGE - The 3D printing material through reasonable coordination between components, does not affect human health during later use, and the strength, toughness, and electrical and thermal conductivity of the material can be achieved. The best use effect can meet the needs of multiple special occasions, the structure of the material is more compact, and the mechanical properties have been fully improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing 3D printing material, which involves preparing 1-adamantane-formaldehyde-modified polylactic acid, toluene, modified aramid pulp, graphene oxide, carbon fiber, nano titanium dioxide, toughening agent, adhesion promoter, brightener, flowability regulator, antioxidant agent and aluminum powder according to mass percentage, adding 1-adamantane-formaldehyde-modified polylactic acid, toluene, adhesion promoter, modified aramid pulp and graphene oxide to a homogenizer, heating and stirring to obtain an initial mixture, then adding carbon fiber, nano-titanium dioxide, toughening agent, brightener, flowability regulator, antioxidant and aluminum powder to the initial mixture in turn, heating and mixing to obtain the final mixture after mixing well, irradiating final mixture with an ultraviolet lamp, and then transferring to a twin-screw extruder, heating and extruding, and the extrusion line is obtained through a draw bar, and cooling extrusion line, and then drying by the take-up and vacuum drying box to obtain the required product.
