Abstract

To provide a material for three-dimensional printing having excellent mechanical characteristics.SOLUTION: A composition 10 of a substance contains at least 10 wt.% of epoxy functionalized secondary-dimensional shape particles 14, 0.1 to 5 wt.% of a carbon nanotube, an epoxy resin, and a curing agent. A method for producing a composition of a substance includes: mixing the epoxy resin, the carbon nanotube, and a solvent, and producing a material; drying the material; mixing the material with the curing agent, and producing the composition of the substance. A method for printing the composition of the substance includes: producing the composition of the substance by combining epoxy functionalized graphene, the carbon nanotube, the epoxy-based resin, and the curing agent; extrusion-printing the composition of the substance in a desired pattern; and curing the pattern.SELECTED DRAWING: Figure 1
