Abstract: A system for additive manufacturing machine energy beam alignment error compensation includes, a calibration table having x-y planar offsets to correct laser alignment errors representing energy beam positional offsets between beam-steering commanded energy beam locations and fiducial marks generated on a burn-paper, a recoater mechanism that distributes successive layers of powder, one or more sensors monitoring the powderbed surface proximal to the beam scan unit, and a processor unit configured to perform a method. The method including collecting sensor data representing height variations across at least a portion of the powderbed surface, deriving dimensional data from the collected data, analyzing the dimensional data to determine a distribution of differences between the powderbed surface and a calibration plane used for a first spatial calibration, and calculating z-axis calibration offset points for inclusion in the calibration table x-y planar offsets.

The binder jets are configured to dispense at least one binder in varying densities onto the particulate in multiple locations to consolidate the particulate to form the component with a variable binder density throughout. The system also includes a plurality of arms extending at least partially across the build platform and supporting the print heads and at least one actuator assembly configured to rotate the print heads and/or the build platform about a rotation axis and move at least one of the print heads and the build platform in a build direction perpendicular to the build platform as part of a helical build process for the component.

Abstract: A method of aligning at least one laser beam of an additive manufacturing arrangement. The method includes measuring a surface of the calibration plate at a plurality of measurement points using the coordinate measuring machine. The method further includes generating a correction field based on the plurality of measurement points using the coordinate measuring machine. The method further includes writing at least one fiducial mark on the surface of the calibration plate using the at least one laser beam. The method further includes generating calibration data for the surface of the calibration plate using the calibration system. The method also includes aligning the laser beam within the additive manufacturing system based on the calibration data and the correction field using the computing device by comparing a position of the fiducial mark from the calibration data with the correction field to determine a corrected position of the laser beam.
