  • Patent number: 11826953
    Abstract: 3-D build jobs having surrogate supports, 3-D printers using surrogate supports, and techniques to support vulnerable regions of build pieces using surrogate supports are disclosed. The surrogate supports are generated in a first material configuration and are offset via a gap from the vulnerable regions. The gap comprises a second material configuration, such as loose or partially fused powder on which the build piece can be supported during 3-D printing. In alternative embodiments, the gap instead includes thin manual ties or a solid body using material that is stronger but more amenable to breaking off without damaging the build piece. Post-processing steps are dramatically reduced as the surrogate supports and gaps facilitate virtually error-free separation from the build piece. In an embodiment, the surrogate supports include a support structure extending to a fixed base underneath, the fixed base being a build plate or a global surrogate.

  • Publication number: 20230241685
    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.
