NOVELTY - Preparation of modified acrylonitrile-butadiene-styrene material doped with graphene-carbon fiber-boron nitride, involves mixing dried styrene-butadiene-styrene and 100 parts mass acrylonitrile-butadiene-styrene with 1-5 parts mass surfactant, adding 1-5 parts mass boron nitride nanosheet, 1-5 parts mass graphene nanosheet, 1-5 parts mass carbon fiber nanosheet, and 5-20 parts mass glass fiber, extruding, drying, and heating. USE - Preparation of modified acrylonitrile-butadiene-styrene material (claimed) for three-dimensional printing. ADVANTAGE - The method provides modified ABS material having excellent crack resistance and shrinkage performance.
