Abstract
A material deposition head includes a body portion and at least one nozzle. The body portion includes a first end, a second end, and a first exterior surface extending from the first end to the second end. The at least one nozzle is coupled to the body portion at or near the second end. The nozzle defines a second exterior surface and a material delivery channel that is fluidically coupled to a fluidized powder source configured to provide a plurality of particles of a material. At least one of the first exterior surface or the second exterior surface includes a microtextured surface configured to reduce a wettability of molten particles of the plurality of particles thereon.
