Optomec direct-write aerosol jetting hose

The apparatus uses an aerosol jet deposition head to form an annularly propagating jet composed of an outer sheath flow and an inner aerosol-laden carrier flow. Miniaturization of the deposition head facilitates the fabrication and operation of arrayed deposition heads, enabling construction and operation of arrays of aerosol jets capable of independent motion and deposition. Arrayed aerosol jets provide an increased deposition rate, arrayed deposition, and multi-material deposition. Provisional Patent Application Ser.

The invention may also be used to print materials onto heat-sensitive targets, is performed under atmospheric conditions, and is capable of deposition of micron-size features. SUMMARY OF THE INVENTION The present invention is a deposition head assembly for depositing a material on a target, the deposition head assembly comprising a deposition head comprising a channel for transporting an aerosol comprising the material, one or more inlets for introducing a sheath gas into the deposition head; a first chamber connected to the inlets; a region proximate to an exit of the channel for combining the aerosol with the sheath gas, thereby forming an annular jet comprising an outer sheath optomec direct-write aerosol jetting hose surrounding an inner aerosol flow; and an extended nozzle.

The deposition head assembly preferably has a diameter of less than approximately 1 cm. The inlets are preferably circumferentially arranged around the channel. The region optionally comprises a second chamber.

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 first chamber is preferably sufficiently long enough to develop a cylindrically symmetric distribution of sheath gas pressure about the channel before the sheath gas is combined with the aerosol.

The deposition head assembly optionally further comprises a third chamber for receiving sheath gas from the first chamber, the third chamber assisting the first chamber in developing a cylindrically symmetric distribution of sheath gas pressure about the channel before the sheath gas is combined with the aerosol.

The third chamber is preferably connected to the first chamber by a plurality of passages which are parallel to and circumferentially arranged around the channel. The deposition head assembly preferably comprises one or more actuators for translating or tilting the deposition head relative to the target.

The invention is also an apparatus for depositing a material on a target, the apparatus comprising a plurality of channels for transporting an aerosol comprising the material, a sheath gas chamber surrounding the channels, a region proximate to an exit of each of the channels for combining the aerosol with sheath gas, thereby forming an annular jet for each channel, the jet comprising an outer sheath flow surrounding an inner aerosol flow, and an extended nozzle corresponding to each of the channels.

The plurality of channels preferably form an array. The aerosol optionally enters each of the channels from a common chamber.

The aerosol is preferably individually fed to at least one of the channels. A second aerosolized material is optionally fed to at least one of the channels. The aerosol mass flow rate in at least one of the channels is preferably individually controllable.

The apparatus preferably comprises one or more actuators for translating or tilting one or more of the channels and extended nozzles relative to the target. The apparatus preferably further comprises an atomizer comprising a cylindrical chamber for holding the material, a thin polymer film disposed on the bottom of the chamber, an ultrasonic bath for receiving the chamber and directing ultrasonic energy up through the film, a carrier tube for introducing carrier gas into the chamber, and one or more pickup tubes for delivering the aerosol to the plurality of channels.

The carrier tube preferably comprises one or more openings. The apparatus preferably further comprises a funnel attached to the tube for recycling large droplets of the material.

Additional material is optionally continuously provided to the atomizer to replace material which is delivered to the plurality of channels.Aerosol based direct-write micro-additive fabrication method for sub-mm 3D metal-dielectric structures aerosol jet, gravure, flexographic, and screen printing [3–6].
