Composite filaments suitable for additive manufacturing may comprise a continuous polymer phase of a first thermoplastic polymer and a second thermoplastic polymer that are immiscible with one another, and electrically conductive particles distributed in the continuous polymer phase, such as microparticles, nanoparticles, or any combination thereof.
