  • Patent number: 10086622
    Abstract: The object of the invention is the provision of apparatuses and methods for stable direct printing of continuous films or discreet structures on a substrate using an internal pneumatic shutter. The invention uses an aerodynamic focusing technique, with a print head comprising an aerosolization source, a flow cell, an aerodynamic lens system, and a pneumatic shutter assembly. The method uses an interchangeable and variable aerodynamic lens system mounted in the flow cell, and an annularly flowing sheath gas to produce a highly collimated micrometer-size stream of aerosolized droplets. The lens system is comprised of a single-orifice or multi-orifice lens coupled to a converging fluid dispense nozzle. A liquid atomizer with temperature control is used to produce an aerosol size distribution that overlaps the functional range of the aerodynamic lens system. The shutter assembly can be attached directly to the print head, or mounted external to the print head in a control module.

  • Patent number: 9694389
    Abstract: The object of the invention is the provision of methods for controlled production of continuous multi-component filaments or discreet structures using a multi-component liquid jet issuing from an orifice. A multi-component jet consists of two or more liquids. The liquids may be miscible or immiscible, and form a co-axially propagating flow along the central axis of a flow cell. The working distance between the exit orifice and a substrate can be as large as 50 mm, so that in-flight processing of the jet is possible. The coaxial flow consists of an outer sheath liquid and an inner sample liquid or composite of liquids. The flow cell and the exit channel of the deposition head are heated so that the pressurized sheath liquid temperature is raised to near or above the boiling point of the sheath liquid at the local atmospheric pressure. The jet exits the deposition head through the orifice, and the outer liquid is evaporated as the jet falls at atmospheric pressure.

  • Patent number: 8919899
    Abstract: The object of the invention is the provision of methods and apparatuses for controlled direct printing of continuous films or discreet structures using a two-component liquid jet issuing from an orifice. The two liquids may be miscible or immiscible, and form an annularly propagating flow along the axis of a deposition head. The flow consists of an outer sheath liquid with a boiling point temperature that is approximately 10 to 40 degrees lower than that of an inner sample liquid. The exit channel of the head is heated so that the pressurized outer sheath liquid is raised to a temperature greater than the boiling point of the sheath liquid at the local atmospheric pressure. The outer liquid is evaporated as the jet exits the orifice and falls at atmospheric pressure. Deposited sample line widths are produced in the range from approximately 1 to 1000 microns.
