Aerosol Jet Printing

Aerosol Jet Printing (AJP) is a particularly innovative technology for the selective deposition of materials (conductive, dielectric, biological, …) at micron-scale, onto any or also non-flat, flexible or 3D substrate.


Aerosol Jet Printing - principle

An ink (solution or suspension of nanoparticules in solvant) in a tank is atomized by ultrasonic or pneumatic mechanism (1). Resulting aerosol jet is then transferred (2) to the writing nozzle (3) where it is driven (sheath gas) towards an X-Y-Z-moving substrate.

Key-features and related advantages for the users

  • No mask required to create any micron-size pattern: this maskless, direct printing technology is particularly indicated for iterative (R&D) or custom-tailored processes (flexibility in production), with obvious material and cost savings accordingly.
  • High resolution: 10μm-width/150 nm-thick minimum feature size for high-resolution, CAD-driven patterning.
  • Local sintering by IR laser beam: compatible with thermally sensitive substrates or components.
  • Versatility: large range of processable materials, from conductive to dielectric, and even semi-conductive or biological materials (ink viscosities as high as 2500 cP).
  • 3D: Sirris’ Optomec AJ300CE equipment allows any material to be deposited at micron-scale onto flat but also 3D and flexible substrates.

Application domains range from electronics to medical as well as any type of surfacepatterning  and functionalization.

This disruptive technology is currently opening new ways in product development and production, by sweeping out major traditional limitations and constrains regarding material incompatibilities, substrate shape, processing cost, … while providing a much higher flexibility.
