Abstract

An additive manufacturing system is configured to manufacture a component. The additive manufacturing system includes a laser device, a build platform, a first scanning device, and an air knife. The laser device is configured to generate a laser beam. The component is disposed on the build platform. The air knife is configured to channel an inert gas across the build platform. The first scanning device is configured to selectively direct the laser beam across the build platform. The laser beam is configured to generate successive layers of a melted powdered build material on the component and the build platform. The build platform is configured to rotate the component relative to the air knife.
