Systems and methods for dynamic shaping of laser beam profiles in additive manufacturing

Abstract:

An additive manufacturing system includes a laser device, a build plate, and a scanning device. The laser device is configured to generate a laser beam with a variable intensity. The build plate is configured to support a powdered build material. The scanning device is configured to selectively direct the laser beam across the powdered build material to generate a melt pool on the build plate. The scanning device is configured to oscillate a spatial position of the laser beam while the laser device simultaneously modulates the intensity of the laser beam to facilitate reducing spatter and to facilitate reducing a temperature of the melt pool to reduce overheating of the melt pool.
