Abstract: Additive manufacturing processes, such as powder bed fusion of thermoplastic particulates, may be employed to form printed objects in a range of shapes. It is sometimes desirable to form conductive traces upon the surface of printed objects. Conductive traces and similar features may be introduced during additive manufacturing processes by incorporating a metal precursor in a thermoplastic printing composition, converting a portion of the metal precursor to discontinuous metal islands using laser irradiation, and performing electroless plating. Suitable printing compositions may comprise a plurality of thermoplastic particulates comprising a thermoplastic polymer, a metal precursor admixed with the thermoplastic polymer, and optionally a plurality of nanoparticles disposed upon an outer surface of each of the thermoplastic particulates, wherein the metal precursor is activatable to form metal islands upon exposure to laser irradiation. Melt emulsification may be used to form the thermoplastic particulates.

Abstract: Additive manufacturing processes featuring consolidation of thermoplastic particulates may form printed objects in a range of shapes. Inorganic nanoparticles disposed upon the outer surface of the thermoplastic particulates may improve flow performance of the thermoplastic particulates during additive manufacturing, but may be undesirable to incorporate in some printed objects. Polymer nanoparticles may be substituted for inorganic nanoparticles in some instances to address this difficulty and provide other advantages. Particulate compositions suitable for additive manufacturing may comprise: a plurality of thermoplastic particulates comprising a thermoplastic polymer and a plurality of polymer nanoparticles disposed upon an outer surface of the thermoplastic particulates, the polymer nanoparticles comprising a crosslinked fluorinated polymer.
