Abstract: Disclosed herein is a material ejector (e.g., print head) geometry having alignment of material inlet channels in-line with microchannels, symmetrically disposed in a propellant flow, to obtain smooth, well-controlled, trajectories in a ballistic aerosol ejection implementation. Propellant (e.g., pressurized air) is supplied from above and below (or side-by-side) a microchannel array plane. Obviating sharp (e.g., 90 degree) corners permits propellant to flow smoothly from macroscopic source into the microchannels.
