NOVELTY - Preparing composition involves injecting nanoparticles into epoxy resin to disperse nanoparticles, and adding 30-50 wt.% curing agent to epoxy resin in which nanoparticles are dispersed, and mixture is semi-cured at temperature of 50-110 degrees C, for 10-100 minutes, where nanoparticles are selected from group consisting of carbon nanotubes, graphene, and silicon carbide. The curing agent is selected from group consisting of diethylenetriamine, triethylenetetramine, tetraethylenepentamine, phthalic anhydride, 4-methylhexahydrophthalic anhydride, cis-1,2-cyclohexanedicarboxylic anhydride. USE - Method for preparing composition for three-dimensional (3D) print. ADVANTAGE - The method enables to prepare composition has good mechanical property, workability, and notable effect.
