    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: Methods of using a toner as a printable adhesive are provided. In embodiments, a method of adhering substrates is provided which comprises disposing a cold pressure fix toner comprising a phase change material on a first substrate via xerography to form an unfused layer of the cold pressure fix toner on the first substrate; placing a second substrate on the unfused layer of the cold pressure fix toner; and subjecting the cold pressure fix toner to a pressure to form a bonded article comprising the first substrate, an adhesive layer formed from the cold pressure fix toner, and the second substrate. Methods of applying an adhesive to a substrate and bonded articles are also provided.
