First, the material is place into an atomizer, which creates a mist of ink-laden droplets that is delivered to the deposition head.
We often formulate our own nano-inks which are then printed using either an Optomec Aerosol Jet machine or an nScrypt microdispensing machine.
A Novacentrix photonic curing or sintering system is then used to thermally process the printed materials. This extremely high power production machine is able to continuously pulse the lamps at frequencies in excess of 1 kHz for R2R applications.
A continuous conveyor belt transports the work pieces beneath the pulsing lamp units for high speed processing. The technique has been successfully used to sinter a variety of printed metal inks e. Optomec Aerosol Jet Machine The Aerosol Jet system is equipped with two pneumatic atomizers for multi-material non-contact printing.
A unique feature of our machine is that it is configured to allow simultaneous printing of both inks when graded material compositions are desired.
The ratios of the two inks can be varied on the fly during printing. The pneumatic atomizers work with nano-inks up to 1,cP viscosity and can produce lines at or under 20 microns wide. A typical line thickness is microns. The system has a motorized z-stage that allows it to print on non-planar surfaces e.
This is useful for printing copper and silver pastes as well as thick resistor pastes.
The system produces results comparable with what one might get when screen printing pastes. The system also allows one to print on non-planar surfaces.
SurfX Atomflo Atmospheric Plasma System Atmospheric plasmas allow us to clean and functionalize substrates prior to printing of the nano-inks. The plasma does not require a vacuum environment, and can be integrated directly within any of the direct-write printing systems.
The plasma chemistry can be tailored to functionalize substrates with either hydrophilic or hydrophobic properties. For printed materials, hydrophilic surface functionalization often results in much greater adhesion of the printed nano-ink with the substrate.Optomec is redefining how products come to market with additive manufacturing.

How the Aerosol Jet 5X Works. Optomec’s unique technology works by first atomizing a given 3D-printing material into a mist. In a separate module, this mist is subsequently focused and deposited with an inert gas by spraying the material through a thin nozzle onto a substrate, which must be about 5 mm ( in) from the initiativeblog.com: Michael Molitch-Hou.
Aerosol Jet technology enables 3D printed electronics. Electronic components such as resistors, capacitors, antennas, sensors, and thin film transistors have all been printed with Aerosol Jet technology.
The performance parameters of printed components, for example the ohm value of a resistor, can be controlled through printing parameters.
Visualization is made possible by adding particles like smoke or other microspheres so that the flow pattern is illuminated. Details regarding the Aerosol Jet® direct-write system, produced by Optomec, are at the heart of Feng’s discussion.
The digital dispensing technology makes up a series of platforms that dispense electronic materials.
Direct-Write Material Printing Capabilities. The Brinkman Lab is uniquely equipped to conduct printed material and device R&D. We often formulate our own nano-inks which are then printed using either an Optomec Aerosol Jet machine or an nScrypt microdispensing machine. Optomec Aerosol Jet printing technology effectively produces 3D printed electronics.
It uses an additive manufacturing process (aka 3D printing or direct write) that prints commercially-available conductive, dielectric, semiconductor and biologic inks onto a variety of .
