A material deposition head (2) may include a body (4) that defines first (6a) and second (6b) ends, an exterior surface (10), an interior surface (12), and one or more material delivery channels (16), where the exterior surface (10) includes fluting (24). In some examples, a system may include a fluted material deposition head (2), a fluidized powder source (84), and an energy source (82). |
