The aerosol pen apparatus of claim 15 wherein the ink vapor condensation removal means further comprises: This is particularly true when devices contain both transmitting and receiving functions. The number of aerosol outputs for the atomizer assembly is preferably variable and depends on the size of the multi-nozzle array.
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.
In this configuration, a cylindrically symmetric pressure distribution is obtained by passing the sheath gas through preferably equally spaced holes in disk centered on the axis of the head. Our micro-structure solution combines Aerosol Jet dispensing technology with an in-flight materials processing mechanism that enables liquid droplets to partially solidify before depositing on a surface.
Of the two configurations shown, the embodiment of FIG. Apparatuses and methods for maskless mesoscale material deposition Filing Date: Moreover, if the plotter is not dynamically re-programmable in the speed of its relative pen movement over the plotting media, the speed must be set to the maximum speed for the slowest pen tip type.
Thus the diameter or width of the miniature deposition head is preferably approximately 1 cm, but could be smaller or larger.
The aerosol optionally enters each of the channels from a common chamber. In addition to the exhibition, Dr. These aspects are shown in greater detail in FIGS. Giridharan, Jyh-Cherng Sheu Assignee s: In his presentation, Dr.
However in this case, the distance between the upper and lower plenum chambers is reduced to enable further miniaturization of the deposition head. 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.
What benefits does this new additive manufacturing method offer over conventional 2D lithographic processing. Development of the sheath gas flow within the deposition head is critical to the deposition characteristics of the system, determines the final width of the jetted aerosol stream and the amount and the distribution of satellite droplets deposited beyond the boundaries of the primary deposit, and minimizes clogging of the exit orifice by forming a barrier between the wall of the orifice and the aerosol-laden carrier gas.
Miniature deposition head is approximately one-fifth the diameter of standard deposition head The use of multiple deposition heads for direct printing applications may be facilitated by using miniaturized deposition heads to increase the number of nozzles per unit area. After the in-flight processing, the droplets can be deposited to form free standing structures.
Returning to the overall system 10 of FIG. Optomec, a leading global supplier of production grade additive manufacturing systems for 3D printed electronics, announced today that the company will showcase its Aerosol Jet systems for 3D production-grade printed electronics at the SEMI Flex conference, held this week at the Hyatt Regency in.
Optomec holds numerous patents and has many patents pending on its proprietary Aerosol Jet process and equipment. History of Printed Electronics The idea of using printing technology to manufacture electronics dates back to the early 20th century, but its use for volume manufacturing didn’t become prevalent until the s.
