  • TEMPERATURE-STABILIZATION OF CONVERTIBLE FUNCTIONAL INKS BY DISRUPTION OF CONDUCTION PATHS
    Publication number: 20230113929
    Abstract: An ink stabilizing composition includes a polymeric network including an acrylate polymer and a plurality of high aspect ratio particles each having an aspect ratio of about 2:1 to about 30:1 and an average particle diameter of about 0.5 to about 1.2 micrometers.

  • ULTRAVIOLET CURABLE EPOXY DIELECTRIC INK
    Publication number: 20230014456
    Abstract: A method of fabricating a three-dimensional (3D) object includes atomizing a pre-polymer composition into an aerosol jet stream. The pre-polymer composition includes an epoxy precursor and a photoacid generator. The method further includes depositing the aerosol jet stream onto a substrate to form a first layer of dielectric ink and curing the first layer of dielectric ink using ultraviolet (UV) light. The method further includes depositing the aerosol jet stream onto the first layer of dielectric ink to form a second layer of dielectric ink. The first layer of dielectric ink and the second layer of dielectric ink overlap by at least 50%.
