Abstract

Additive manufacturing (AM) and printing concepts have been employed in various fields, including electronics and functional device manufacturing industries. However, to date, the ability to print multifunctional materials and devices have been limited with the current printing technologies. Here we present a new printing concept for additive nanomanufacturing (ANM) of multifunctional material and structures on various substrates. In this method, we show that a stream of pure nanoparticles can be laser-generated in real-time at room temperature and at atmospheric pressure. These nanoparticles are then directed toward a printer nozzle and laser-sintered in-situ to form crystals with desired patterns and structures. Currently, with our ANM systems, we have achieved printing various materials (TiO2, BTO, ITO) on different substrates, including SiO2, PDMS, and paper. We believe this new ANM concept would bring excitement into the field of printing functional structures devices.
