  • Publication number: 20130344232
    Abstract: A method of forming a conductive feature on a three-dimensional object may include depositing a composition comprising nanoparticles onto a portion of the three-dimensional object, and annealing the composition to form the conductive feature. In another embodiment, a method of forming a conductive feature on a three-dimensional object may include printing a composition comprising nanoparticles to produce a contiguous line over a non-planar portion of the three-dimensional object, and heating the composition to form a conductive feature that has conductivity throughout.

  • Publication number: 20120190765
    Abstract: Curable solid inks which are solid at room temperature and molten at an elevated temperature at which the molten ink is applied to a substrate. In particular, the curable solid inks of the present embodiments retain the advantages of handling, safety, and print quality usually associated with conventional curable solid phase change inks but have replaced the petroleum-based materials generally used in the conventional inks with renewable “green” materials to provide a robust and environmentally-friendly curable solid ink.
