Abstract: Wet-mixing process, electrically-conductive fused deposition modeling material, 3D printable fused deposition modeling (FDM) filament, electrically-conductive ink, and associated methods. A wet mixing process includes dissolving a thermoplastic with a solvent, thereby creating a thermoplastic-based solution, suspending conductive carbon nanofibers (CNFs) in the thermoplastic-based solution, and mixing the thermoplastic-based solution to distribute the CNFs throughout the solution. The solvent may be evaporated from thermoplastic-based solution to form an electrically-conductive FDM material having a solid matrix of the thermoplastic with CNFs dispersed homogenously throughout the solid matrix. A 3D printable fused deposition modeling filament may be formed of the FDM material. An electrical circuit component may be additively manufactured with a 3D printer and the FDM material. An electrically-conductive ink may be formed from the thermoplastic-based solution.
