A new solvent-free method of aerosol printing for fabrication conductive structures in the form of lines with a minimum width of 60 µm and an average thickness of up to 6 µm has been proposed and investigated. This method is based on dry deposition of focused beam of silver nanoparticles synthesized by the multi-spark discharge generator. Printed and sintered microstructures showed low electrical resistivity equal to 7.5 μΩ∙cm, which is five times greater than the resistivity of bulk silver. The described method of dry aerosol printing without solvents could be a promising alternative to conventional «wet» aerosol jet printing.
