Abstract

We propose an entirely new printing technology based on an optical vortex laser induced forward transfer (OV-LIFT), which allows the production of microdroplets formed of an ultrahigh viscosity silver nano-ink (viscosity: 11 Pa∙s). The microdroplets are propelled and printed to be a dot with a diameter of <50 μm on a receiver film.
