Multi-beam laser scanning system (20) (A) includes: a laser (22) for generating an initial laser beam; a beam splitter (24) for splitting the initial laser beam into a first laser beam and a second laser beam; a first scanning unit for deflecting the first laser beam into a desired direction; a second scanning unit for deflecting the second laser beam into a desired direction; and a control unit (26), which is connected with the first and second scanning unit and created to output control signals to first and second scanning unit, in order to produce an object. Multi-beam laser scanning system (20) (B) comprises: a laser (22) for generating an initial laser beam; a first beam splitter (24) for splitting the initial laser beam into a first laser beam and a second laser beam; a second beam splitter for splitting the first laser beam into a third laser beam and a fourth laser beam; a third beam splitter for splitting the second laser beam into a fifth laser beam and a sixth laser beam; a first scanning unit for deflecting the third laser beam into a desired direction; a second scanning unit for deflecting the fourth laser beam into a desired direction; a third scanning unit for deflecting the fifth laser beam into a desired direction; a fourth scanning unit for deflecting the sixth laser beam into a desired direction; and a control unit, which is connected with the first to fifth second scanning unit and created to output control signals to first and fifth scanning unit, in order to produce an object; and a multi-beam laser technique, comprising producing an initial laser beam; splitting the initial laser beam into a first laser beam and a second laser beam; and deflecting the first and the second laser beam into desired directions based on control signals, in order to produce an object.
