Publication number: 20220410579Abstract: An aerosol-based printing apparatus is provided capable of producing an aerosol stream at a constant rate and constant material deposition to a substrate to provide high-definition, high-resolution traces. The aerosol-based printing apparatus provides production, transport, and delivery of an aerosol stream at a constant rate for a period of time of at least 8 hours and other instances more than 24 continuous hours of constant operation. By inhibiting bulging and necking of the deposited trace, superior line width tolerances are achieved, and such tolerances are maintained for extended periods of time, thereby allowing for both the deposition of complex traces as well as consistent manufacture of duplicate articles that maintain the tolerances across a production ran. The accumulation of fluids in the aerosol and gas transport conduits are eliminated, thereby eliminating the need for purge or cleaning cycles and allowing for uninterrupted operation for a minimum of 24 hours.Type: ApplicationFiled: September 25, 2020Publication date: December 29, 2022Applicant: INTEGRATED DEPOSITION SOLUTIONS, INC.Inventors: Marcelino Essien, David M.

HIGH-DEFINITION AEROSOL PRINTING USING AN OPTIMIZED AEROSOL DISTRIBUTION AND AERODYNAMIC LENS SYSTEM
Publication number: 20220088925Abstract: An apparatus for printing discrete high-resolution high-density features on a surface is provided using an aerosol stream. An aerosol chamber has a transport gas that enters through a port and entrains aerosol in an aerosol chamber to form an aerosol-laden transport gas. A flow cell is provided that has a flow cell channel and sheath gas conduits. The aerosol-laden transport gas passes through the flow cell channel and is surrounded by sheath gas passed through the sheath gas conduits. At least one aerodynamic lens receives the aerosol-laden transport gas surrounded by sheath gas. A method of printing the aerosol droplets from the aerosol-laden transport gas onto the substrate with a mean diameter of 0.5 to 8 microns is also provided.Type: ApplicationFiled: September 21, 2021Publication date: March 24, 2022Applicant: Integrated Deposition Solutions, Inc.Inventors: Marcelino Essien, David M.

Patent number: 10124602Abstract: The object of the invention is the provision of apparatuses and methods for maskless direct printing of continuous films or discreet structures on a substrate using aerodynamic focusing. The method uses an interchangeable and variable aerodynamic lens system and an annularly flowing sheath gas to produce a highly collimated micrometer-size stream of aerosolized droplets. The lens system is comprised of a multi-orifice lens or a single-orifice lens or lenses coupled to a converging fluid dispense nozzle. A combined annular sheath and aerosol flow is propagated through at least two orifices. A liquid atomizer with temperature control, variable continuous or pulsed excitation, and constant or variable frequency, is used to produce an aerosol size distribution that overlaps the functional range of the aerodynamic lens system. The combined flow through the lens system produces a narrow, highly stable subsonic jet that remains collimated for as much as one centimeter beyond the orifice of the nozzle.Type: GrantFiled: October 29, 2015Date of Patent: November 13, 2018Assignee: Integrated Deposition Solutions, Inc.Inventor: Marcelino Essien

Patent number: 10086622Abstract: 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.Type: GrantFiled: June 11, 2017Date of Patent: October 2, 2018Assignee: Integrated Deposition Solutions, Inc.Inventors: Marcelino Essien, David Michael Keicher

Patent number: 9694389Abstract: 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.Type: GrantFiled: May 10, 2013Date of Patent: July 4, 2017Assignee: Integrated Deposition Solutions, Inc.Inventors: Fa-Gung Fan, David Bohling, David Michael Keicher, Marcelino Essien

Publication number: 20140035975Abstract: 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.Type: ApplicationFiled: May 10, 2013Publication date: February 6, 2014Applicant: INTEGRATED DEPOSITION SOLUTIONS, INC.Inventors: Marcelino Essien, David Michael Keicher
