Abstract: A system may include a printhead for ejecting a first fluid including a polymer, the ejected first fluid forming a substrate with a thermal conductivity of less than 0.5 W/(m-K); a spreader to spread a layer of metal particulate on the substrate, wherein the printhead further ejects a second fluid, the ejected second fluid masking a portion of the layer of metal particulate on the substrate; and a pulse irradiation light source to fuse an unmasked portion of the layer of metal particulate.
