Abstract: A multi-beam laser scanning system comprising a laser, a beam splitter, a first scanning unit, a second scanning unit, and a control unit is disclosed herein. The laser is used for generating an initial laser beam. The beam splitter is used for splitting the initial laser beam into a first laser beam and a second laser beam. The first scanning unit is used for deflecting the first laser beam along a desired direction. The second scanning unit is used for deflecting the second laser beam along a desired direction. The control unit is coupled to the first and second scanning units and arranged to output control signals to the first and second scanning units to manufacture an object.
