Also, a method for printing a three-dimensional (3D) article by printing such a filament in a fused filament fabrication (FFF) printer, wherein the fused filament fabrication (FFF) printer carries out a pattern of printing synchronized with the order of the segments in such a filament. Further, a method and device for fabricating such thermoplastic filaments.

Abstract: A dispersion of nanoplatelet graphene-like material, such as graphene nanoplatelets, in a solid or liquid dispersion media wherein the nanoplatelet graphene-like material is dispersed substantially uniformly in the dispersion media with a graphene-like material dispersant. Such dispersions may be used to prepare articles by three-dimensional (3D) printing, as well as to provide electrically conductive inks and coatings, chemical sensors and biosensors, electrodes, energy storage devices, solar cells, etc. Liquid dispersions may be prepared, for example, by sonication of solutions of graphite flakes, dispersant, and liquid dispersion media, while solid dispersions may be prepared, for example, by combining the melted polymer with the liquid dispersion, dissolving the solid polymer in a miscible solvent and then blending with the liquid dispersion, dissolving the solid polymer in the liquid dispersion, or polymerizing one or more monomers in the liquid dispersion to form the solid polymer.
