  • Printhead, system and method for direct write vapor deposition
    Patent number: 12728590
    Abstract: A printhead for direct write vapor deposition comprises a nozzle body including a reservoir for holding a material to be printed and a nozzle head protruding from the nozzle body. The nozzle head includes a nozzle opening for ejection of the material as a vapor-phase ink. The nozzle opening is in fluid communication with the reservoir. The nozzle head may protrude from the nozzle body a distance of at least 10 microns. A system for direct write vapor deposition includes the printhead, a heat source positioned to heat the printhead, a substrate in opposition to the nozzle opening for deposition of the vapor-phase ink, and an x-y-z motion stage configured to move the substrate relative to the printhead.
