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: 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 component includes a body, and an interface in the body defining a first and second portion of the body made by different melting beam sources of a multiple melting beam source additive manufacturing system during a single build. The component also includes a channel extending through the body. The channel includes an interface-distant area on opposing sides of the interface, each interface-distant area having a first width. The channel also includes an enlarged width area fluidly communicative with the interface-distant areas and spanning the interface, the enlarged width area having a second width larger than the first width. Any misalignment of the melting beams at the interface is addressed by the enlarged width area, eliminating the problem of reduced cooling fluid flow in the channel.

Abstract: Additive manufacturing systems are disclosed. The additive manufacturing system may include a sintering device configured to sinter a powder material to form a component, and an actuator coupled to the sintering device. The actuator may adjust a position of the sintering device. Additionally, the system may include at least one computing device operably connected to the actuator and the sintering device. The at least one computing device may control a movement of the sintering device by performing processes including determining an exposure pattern for the sintering device for sintering the powder material based on a geometry of the component. The exposure pattern may include at least one exposure track extending between two sides of the component. The computing device(s) may also perform processes including moving the sintering device, using the actuator, in the determined exposure pattern to sinter the powder material to form the component.
