Abstract: Additive manufacturing systems (AMS) are disclosed. The AMS may include a movable build platform, and a calibration system operably connected to the build platform. The calibration system may include a reflective element operably coupled to the build platform, a first calibration model positioned above and vertically offset from the reflective element, and a first camera substantially aligned with the first calibration model. The first camera may be visually aligned with the reflective element to capture a first reflective image of the first calibration model as reflected by the reflective element. The calibration system may also include at least one computing device operably connected to the build platform and the first camera, and configured to calibrate the build platform by: adjusting an actual inclination of the build platform in response to determining the first reflective image differs from a predetermined image of the first calibration model.

Abstract: A test feature is disclosed that is formed during metal powder additive manufacturing of a production part. The test feature may include a metal powder sample capsule including a chamber for capturing unfused powder from the metal powder additive manufacturing, and a removable cap closing an end of the chamber. Alternatively, a test feature may include a quality control (QC) part, and at least one additional test element including a metal powder sample capsule integrally coupled to the QC part and including a chamber for capturing unfused powder from the metal powder additive manufacturing. The QC part is identical to the production part excepting the at least one test element. The QC part and the at least one test element are formed during the same metal powder additive manufacturing as the production part.

Abstract: A damaged applicator identifier system for an additive manufacturing (AM) system, and AM system including the same are disclosed. The damaged applicator identifier system may include a damaged applicator identifier determining whether the active applicator is damaged by identifying a non-planar surface in a layer of raw material on a build platform of the AM system after formation of the layer by the active applicator. A damaged applicator controller is configured to cause replacement or repair of the damaged, active applicator in response to the damaged applicator identifier identifying the damaged, active applicator.

Abstract: Additive manufacturing systems (AMS) are disclosed. The AMS may include a build plate positioned directly on a movable build platform, and a recoater device positioned above the build plate. The recoater device may include a blade. Additionally, the AMS may include a calibration system operably connected to the recoater device. The calibration system may include at least one measurement device coupled or positioned adjacent to the recoater device, and at least one computing device operably connected to the measurement device(s). The computing device(s) may be configured to calibrate the recoater device by adjusting a height of the blade of the recoater device relative to a reference surface of a component of the AMS in response to determining a pre-build distance between the blade of the recoater device and the reference surface differs from a desired distance. The pre-build distance may be determined using the measurement device(s).

Abstract: Methods for aligning a pair of calibrated lasers of a laser additive manufacturing system in an overlap region in which the pair of calibrated lasers selectively operate are provided. Respective first and second plurality of layers of a test structure are formed in the overlap region of the pair of calibrated lasers solely using a first calibrated laser of the pair of calibrated lasers and then solely using a second calibrated laser of the pair of calibrated lasers. The test structure forming creates an outer surface of the test structure corresponding to the overlap region. A dimension(s) of an offset step(s) created between the first plurality of layers and the second plurality of lasers in the outer surface of the test structure is/are measured. The lasers are aligned by applying the dimension(s) of the offset step(s) as an alignment correction(s) to at least one of the pair of calibrated lasers.
