Optomec Introduces Aerosol Jet Technology for 3D Printed Electronics (Video)

Optomec Aerosol Jet printing technology is an additive manufacturing process (aka 3D printing or direct write) that prints commercially-available conductive, dielectric, semiconductor and biologic inks onto a variety of 2D or 3D plastic, ceramic, and metallic substrates. The result is 3D digital printing that eliminates the need for hard tooling photomasks or stencils and enables engineering changes to be quickly implemented by simply modifying the design file.

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. This can be accomplished because the Aerosol Jet process supports multiple ink input devices allowing materials to be switched or even blended during printing.

How Aerosol Jet Technology Works:

The Aerosol Jet process uses aerodynamic focusing to precisely and accurately deposit electronic Inks onto substrates. The ink is placed into an atomizer (1), which creates a dense mist of material laden droplets between 2 to 5 microns diameter (2). The aerosol mist is then delivered to the deposition head where it is focused by a sheath gas (3), which surrounds the aerosol as an annular ring.
