Abstract: A 3D printing system includes a reservoir for a UV-curable dielectric material in communication with a first nozzle configured to print the UV-curable dielectric material onto a substrate and a reservoir for a low CTE filler in communication with a second nozzle configured to print the low CTE filler onto the substrate, and a reservoir for a conductive ink in communication with a third nozzle configured to print the conductive ink onto the substrate. The 3D printing system prints the UV-curable dielectric material and the low CTE filler such that the printed low CTE filler mixes with the printed UV-curable dielectric material and forms a UV-curable dielectric layer with the low CTE filler dispersed therein.
