3d one kind of printing with a conductive wire abs / pla composite material and its preparation method and application

The present invention provides a 3D printing with a conductive wire ABS / PLA composite material, comprising the percentages by weight is made of material: Bulk ABS 15 ~ 30%; emulsion ABS 15 ~ 30%; styrene - acrylonitrile - glycidyl methacrylate copolymer 1 to 10%; butyl triphenylphosphonium bromide 0.01% to 0.05%; nickel metal powder of 5 to 15%; 30% to 50% of polylactic acid; MWNTs 1 to 5% ; graphene microchip 1 to 5%, the present invention employs a nickel powder, a graphene sheet and a micro-optimization with carbon nanotubes, the conductivity obtained required to achieve a lower volume resistivity at a lower conductive additive content, different particle sizes mixed ABS material such that the composite material exhibits a bimodal particle size distribution, and increased fracture toughness, ABS and PLA were compatible with good continuity, especially for a highly conductive material strip material required to print double-headed 3D.
