Methods for removing support structures in additively manufactured parts are disclosed. A method in accordance with an aspect of the present disclosure comprises inserting a demolition object in a first state into a hollow portion of a 3-D printed part, breaking a support structure within the hollow portion by contact with the demolition object, changing the demolition object into a second state while the demolition object is within the hollow portion of the 3-D printed part, and removing the demolition object from the hollow portion of the 3-D printed part.

Removal of supports, and other materials from surface, and within hollow 3D printed parts

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.
