Optomec AJ300 Printer
The Optomec AJ300 series system is a 2.5 D printer owned by Prof. Jon Willmott and his research group. They have experience using the printer to print antennas and many other things.

The Optomec AJ300 series system is a prototyping additive manufacturing flatform for 2.5D printing. It utilises Aerosol Jet technology to print an enormous variety of conductive, semiconductor and dielectric materials onto non-planar surface geometries and traditional and unconventional substrates.
The moving stage of the printer is accurate to 1 µm and the nozzle provides a minimum feature size of ~10 µm. The system includes a 700 mW laser for post processing inks allowing material to be printed onto temperature sensitive substrates.
A design can be printed from a CAD drawing in minutes affording rapid, successive rounds of prototyping and testing to iteratively perfect antenna performance.
