Abstract
An apparatus includes a jet that applies a liquid binder to an application surface and a particle applicator. The particle applicator includes a particle reservoir with at least one movable surface, an electrically controlled actuator that causes vibrations of the movable surface, and a dispersal port though which particles can exit the particle reservoir. A controller is coupled to cause the vibrations via the actuator. The vibrations result in movement of the particles through the dispersal port towards the liquid binder on the application surface.
