Abstract: Methods of additively manufacturing a three-dimensional object include irradiating a first build plane region using a first energy beam defining a beam diameter, the first energy beam travelling along a first oscillating path in a first direction to consolidate a first wall defining a thickness perpendicular to the first direction, wherein a build material adjacent a first side of the first wall and the build material adjacent a second side of the first wall, opposite the first side of the first wall, remains unconsolidated; and wherein the thickness of the first wall is greater than the beam diameter.

Abstract: A direct metal laser melting (DMLM) system includes a laser device configured to generate a melt pool in a powder bed based on a build parameter. In addition, the DMLM system includes a confocal optical system directed at the melt pool and configured to receive an optical signal emitted by the melt pool. The DMLM system further includes an optical sensor operatively coupled to the confocal optical system that is configured to receive the optical signal and to generate an electrical signal in response to the optical signal. A computing device is configured to receive the electrical signal from the optical sensor and to generate a control signal in response. The control signal is configured to modify the build parameter of the direct metal laser melting system in real-time to adjust at least one of a melt pool size and a melt pool temperature to achieve a desired physical property of the component.
