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).
