A system and method for coating a substrate, the system including integrated powder coating material preparation and deposition of powder coating material onto a substrate. The system includes a feed input that processes the powder coating materials for use in a filament extension atomizer. The filament extension atomizer stretches fluid filaments of the powder coating material to form droplets of powder coating material. The droplets of powder coating material are partially cooled to prevent agglomeration and to form a powder coating material suitable for electrostatic deposition. The cooled powder coating material is electrostatically charged and directed onto the substrate surface, where it is deposited due to the electrostatic potential between the substrate and cooled droplets. The deposited powder coating material is then cured to the substrate to form a cohesive film of coating material across the substrate.

A droplet applicator for generating molten metal droplets having a volume in the range of nanoliters to milliliters. The droplet applicator includes a first wire feeding device, which vertically moves a first wire including a first wire material, and a first wire blocking device, which is configured to block the first wire. The first wire feeding device and the first wire blocking device are arranged within a housing, A wire heating device is arranged, vertically flush, below the first wire feeding device. The wire heating device heats regions of the first wire that have been introduced into the wire heating device by the first wire feeding device, to a temperature above a melting temperature of the first wire material.
