Optomec direct-write aerosol jetting holley

The method of claim 8 wherein the step of transporting a sheath gas comprises providing a sufficiently long flow path so that the sheath gas flows substantially parallel to a flow direction of the aerosol before the combining step. Miniaturization also facilitates the fabrication and operation of arrayed deposition heads, enabling construction and operation of arrays of aerosol jets capable of independent motion and deposition.

The sheath gas flow enters sheath plenum chamber through at least one sheath gas port Nozzle configurations include, but are not limited to, linear, rectangular, circular, polygonal, and various nonlinear arrangements.

The diameter of the emerging stream and therefore the linewidth of the deposit is controlled by the exit orifice size, the ratio of sheath gas flow rate to carrier gas flow rate, and the distance between the orifice and the target. The miniature deposition head preferably comprises the same basic internal geometry as the standard head, in that an annular flow is formed between the aerosol and sheath gases in a configuration similar to that of the standard deposition head.

Arrayed aerosol jets also provide for increased nozzle density for high-resolution direct write applications, and can be manufactured with customized jet spacing and configurations for specific deposition applications. The deposition head of claim 3 wherein said chamber is concentric with said tube.

The first chamber is optionally external to the deposition head and develops a cylindrically symmetric distribution of sheath gas pressure about the channel before the sheath gas is combined with the aerosol. The deposition head assembly preferably has a diameter of less than approximately 1 cm.

No axial constrictors are used, and the flows typically do not reach supersonic flow velocities, thus preventing the formation of turbulent flow, which could potentially lead to a complete constriction of the flow.


Provisional Patent Application Ser. This iframe contains the logic required to handle Ajax powered Gravity Forms.

Other objects, advantages and novel features, and further scope of applicability of the present invention will be set forth in part in the detailed description to follow, taken in conjunction with the accompanying drawings, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention.

A method of depositing a material, the method comprising the steps of: Aerosol tube may extend partially or fully to the bottom of sheath gas chamber Thus the diameter or width of the miniature deposition head is preferably approximately 1 cm, but could be smaller or larger. In this configuration, recognition and alignment, deposition, and laser processing are performed in a serial fashion.

In this configuration, the sheath gas enters the plenum chamber from ports located on the side of the chamber, and flows upward to the sheath gas channels As with the aerosol carrier gas, the sheath gas flowrate is preferably controlled by a mass flow controller.

The carrier tube preferably comprises one or more openings.

The aerosol enters sheath gas chamber through an opening in the top of aerosol tube The tightly packed components within these assemblies can be precisely wired or linked together on a circuit board, ensuring that no extra space or time is wasted during the manufacturing process.

Sheath gas channels are preferably equally spaced about the axis of the device. As in the configuration of FIG.

The deposition head assembly preferably comprises one or more actuators for translating or tilting the deposition head relative to the target.

Phone This field is for validation purposes and should be left unchanged. For example, when the aerosol is formed from an aqueous solution, water vapor may be added to the carrier gas or the sheath gas to prevent droplet evaporation.Sep 04,  · This video from the Rochester Institute of Technology's Brinkman Lab shows Optomec's Aerosol Jet process printing copper nanoink from Intrinsiq materials on a paper substrate.

The lines are. Aerosol Jet® Printing onto 3D and Flexible Substrates Tyler Blumenthal, Vincent Fratello, Giovanni Nino, Keith Ritala Here we demonstrate how direct-write printing has establishing itself as an enabling has been utilizing an Optomec Aerosol Jet® (AJ) direct write printing system that can deposit a variety of materials onto nearly any.

Aerosol jetting conductive inks is a popular method for scribing circuits on 3D surfaces [17,26, 27]. Aerosol jetting tends to exhibit higher conductivity than extrusion systems, but are imitated. Optomec is redefining how products come to market with additive manufacturing.

Encompassing printers, software, materials and applications expertise, our innovative and comprehensive offerings span the entire product life cycle enabling components and features not possible before and transforming how customers design, build and maintain critical products and parts.

The technology behind Aerosol Jet enables printing of interconnects on both 2D and 3D substrates.

For 2D applications, multi-level interconnects can be created by printing a dielectric material at circuit cross over points – in essence emulating a multi-layer circuit board but on a single layer.
