NOVELTY - Modifying acrylonitrile butadiene styrene material involves mixing acrylonitrile butadiene styrene and styrene butadiene styrene. The obtained mixture is added with surface active agent. The obtained mixture is dried. The obtained dried mixture is added with glass fiber and boron nitride and graphene nano sheet. The obtained mixture is carried out with screw extruding. The obtained mixture is heated, and then dried. USE - Method for modifying acrylonitrile butadiene styrene material for three dimensional printing of boron nitride and graphene nanosheets (claimed). ADVANTAGE - The method enables to modify acrylonitrile butadiene styrene material with improved shrinkage performance.
