Abstract
3D printing technologies have received a lot of attentions because of the high flexibility of the process as well as the capability of producing complex shaped and high detailed artifacts with ease. This study focuses on the development of acrylonitrile butadiene styrene (ABS)/graphene composite materials, which can be used as a filament for the melt extrusion 3D printing or FDM 3D printing technique. Since the dispersity of graphene in the polymer matrix is the key parameter of controlling the properties of the composites, the ABS/graphene masterbatches with high concentration of graphene were produced via three techniques: dry mixing; solvent mixing and coagulation techniques. The obtained high concentration ABS/graphene masterbatches were then mixed with pure ABS and melt extruded to produce ABS/graphene composites filament with 1 wt% of graphene. The ABS/graphene composites preparing via solvent mixing and coagulation were found successfully 3D printed. The dry mixing method brought about the aggregation of graphene particle and failed the print.
