Abstract: Apparatus and methods for removing and/or destroying support structures associated with objects fabricated using additive manufacturing techniques are presented herein. Structural supports may be used during an additive manufacturing process to prevent deformation of a build piece (e.g., three dimensional (3D) printed structure). In some examples, a build piece may be manufactured such that the structural supports are internal to the completed build piece. However, removing the structural supports may reduce the weight of the build piece and reduce the amount of debris trapped within the build piece. Thus, certain aspects of the disclosure are directed to a hose including a bendable and elongated tube member as well as a fracturing member configured to fracture an internal support structure within an additively manufactured part.

Abstract: 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.
