Abstract:
An additive manufacturing system configured to manufacture a component including scan strategies for efficient utilization of one or more laser arrays. The additive manufacturing system includes at least one laser device, each configured as a laser array, and a build platform. Each laser device is configured to generate a plurality of laser beams. The component is disposed on the build platform. The at least one laser device is configured to sweep across the component and the build platform in at least one of a radial direction, a circumferential direction or a modified zig-zag pattern and simultaneously operate the one or more of the plurality of individually operable laser beams corresponding to a pattern of the layer of a build to generate successive layers of a melted powdered material on the component and the build platform corresponding to the pattern of the layer of the build. A method of manufacturing a component with the additive manufacturing system is also disclosed.
