Abstract
An additive manufacturing apparatus includes a platform, a dispenser to dispense layers of feed material on the platform, and a fusing system including an energy source to generate an energy beam having an adjustable intensity profile, an actuator to cause the energy beam to traverse across an outermost layer of feed material, and a controller coupled to the actuator and the energy source. The controller is configured to cause the energy source to adjust the intensity profile of the energy beam on the outermost layer of feed material based on a traversal velocity and/or a traversal direction of the light beam across the outermost layer of feed material.
