Abstract: An additively manufactured component and a method for manufacturing the same are provided. The additively manufactured component includes a cross sectional layer having a surface surrounding the cross sectional layer. The cross sectional layer is formed by moving a focal point of an energy source over a bed of additive material. A surface irregularity is formed on the surface by manipulating the energy level of the energy source. The surface may include a datum feature positioned at a predetermined location relative to the surface irregularity and the surface irregularity may be greater than a surface roughness of the surface but less than one millimeter.

Abstract: A system and method for calibrating an acoustic monitoring system of an additive manufacturing machine includes installing a calibration system on the machine and performing a calibration process. Specifically, the calibration system includes a calibration platform removably mountable to a build platform of the additive manufacturing machine and having calibrated acoustic source mounted thereon for defining a measurement standard. The acoustic waves generated by the calibrated acoustic source are measured by the acoustic monitoring system and compared to the known measurement standard to determine whether system adjustments would improve process tolerances or uniformity.

Abstract: The present disclosure generally relates to methods and apparatuses for laser shock peening during additive manufacturing (AM) processes. Such methods and apparatuses can be used to embed microstructural and/or physical signatures into manufactured objects, and such embedded chemical signatures may find use in anti-counterfeiting operations and in manufacture of objects with multiple materials.

Abstract: A method and apparatus for additive manufacturing is provided whereby a curtain of powder is provided adjacent a vertically oriented build plate, and a laser melts or sinters the powder over a region of the build plate. The curtain of powder is moved relative to the build plate to maintain the same distance between the curtain and the previously deposited layer, and the process repeated to provide a three dimensional structure on the build plate.

Abstract: A method for inspecting an additive manufacturing process in which a directed energy source is used to create a weld pool at an exposed build surface of a mass of powdered material, and selectively fuse the powdered material to form a workpiece. The inspection method includes: using a noncontact method to generate an acoustic wave in the build surface; using a noncontact method to measure displacement of the build surface in response to the acoustic wave; and determining at least one sub-surface material property of the workpiece by analyzing the displacement of the build surface.

Abstract: A method of monitoring an additive manufacturing process in which a layer of powdered material is deposited in a recoating process so as to define a build surface, and a directed energy source is used to create a weld pool in the build surface and selectively fuse the powdered material to form a workpiece. The method includes: measuring a vibration signal profile generated by the recoating process; and controlling at least one aspect of the additive manufacturing process in response to the measured vibration signal profile.
