Abstract
The three-dimensional shaping device () is provided with a layer forming device () to form a layer of metal powder () on a shaping object, and a laser light irradiation device () to irradiate the layer of metal powder () formed by the layer forming device () with a laser light (). The laser light () to be used in the three-dimensional shaping device () has a pulsed output waveform with a frequency of 5 to 200 kHz, a pulse width of 5 to 200 μs 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 () by two successive pulses of the laser light () 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.
