Abstract: Ultrasonic additive manufacturing (UAM) of surface members for a box-like part such as a crash structure or load-bearing structure in a vehicle is disclosed. In one aspect of the disclosure, a method for building a box-like part includes 3-D printing separately, using UAM, the one or more flat surface members in a horizontal plane relative to a print substrate. The method further includes assembling together the surface members at or proximate respective edges thereof to form the box-like part. In some embodiments, protrusions and other features are added to the surface members. In embodiments involving crash structures, trenches are machined into the inner surfaces to enable tailored deformation of the crash structure during an impact event.

Abstract: A printer and methods for additive manufacturing a build piece may include a camera and an optical spectrometer obtaining spectral information and optical information from a region of melted material to determine a defect condition based on an evaluation of processed spectral or optical information. A processor or a computer may process the obtained and optical information and determine a defect condition during the additively manufacturing process. The obtained spectral and optical information may be of the region of the melted material, a melt pool and a mushy zone. The printer and method may include a controller configured to modify a process parameter to shape the weld pool to obtain a desired effective absorptivity of a portion of the weld pool, e.g., to increase the effective absorptivity relative to an absorptivity of a surface of the powder or material deposited by the depositor and to maintain an acceptable temperature of the weld pool during the additively manufacturing process.

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: Aspects are provided for additively manufacturing a component with reduced surface roughness based on direct energy deposition (DED). A DED apparatus for additively manufacturing a component includes a material supply, one or more deposition heads coupled to the material supply to deposit feedstock from the material supply, and an energy source configured to heat the feedstock as the feedstock is being deposited by the one or more deposition heads. The energy source is configured to reheat one or more portions of a surface of the component to reduce surface roughness as the component is being additively manufactured. The one or more deposition heads may also comprise a plurality of deposition heads which are sized to deposit the feedstock from the material supply at different resolutions to form a surface of the component with reduced surface roughness as the component is being additively manufactured. Thus, structural integrity may be improved.
