  • Three-dimensional shaping method and three-dimensional shaping device
    Patent number: 11794253
    Abstract: The three-dimensional shaping device (100) is provided with a layer forming device (10) to form a layer of metal powder (90) on a shaping object, and a laser light irradiation device (20) to irradiate the layer of metal powder (90) formed by the layer forming device (10) with a laser light (25). The laser light (25) to be used in the three-dimensional shaping device (100) has a pulsed output waveform with a frequency of 5 to 200 kHz, a pulse width of 5 to 200 ?s and a peak output of 10 to 500 W. Further, an overlap rate, which is a rate at which irradiation spots on the layer of metal powder (90) by two successive pulses of the laser light (25) overlap with each other, is 50 to 99.9%. Hereby, it is possible to provide a three-dimensional shaping method and a three-dimensional shaping device which can shape a shaping body having a narrower shaping width.
