Systems and methods for rotational additive manufacturing are disclosed. An apparatus in accordance with an aspect of the present disclosure comprises a build floor, a depositor system configured to deposit a layer of powder onto the build floor, a motor system causing a rotational motion between the depositor system and the build floor, wherein the depositor system deposits the layer of powder during the rotational motion, a receptacle wall configured to contain the powder on the build floor, an energy beam source configured to apply an energy beam in an active area of the layer of powder to selectively fuse a portion of the powder in the active area to form a portion of a build piece and a gas flow system configured to provide a gas flow across the active area while the energy beam selectively fuses the portion of the layer of powder in the active area.
