COMBINATION CONTINUOUS WAVE AND PULSED LASER ADDITIVE MANUFACTURING SYSTEM AND RELATED METHODS

Abstract: additive manufacturing systems and associated methods are disclosed herein. in some embodiments, the additive manufacturing system includes a build chamber that has an active build region, an energy beam system positioned to direct energy beams toward the active build area, and a controller operably coupled to the energy beam system. during an additive manufacturing process, the controller can control the energy beam system to execute a hybrid sintering process. for example, for a first region of a planned build object, the controller can operate the energy beam system in a continuous wave mode to generate a first energy beam to sinter powder in the first region. then, for a second region, the controller can operate the energy beam system in a pulsed mode to generate a second energy beam with to sinter the second region.
