三次元造形物製造用粉末、三次元造形物製造用組成物および三次元造形物の製造方法

Japanese Patent JP7472467

B2

A three-dimensional shaped article producing powder according to the present disclosure includes a plurality of metal particles, and is used for producing a three-dimensional shaped article by laminating a plurality of layers while joining the metal particles to one another by irradiation with a laser beam, wherein as the metal particles, first metal particles and second metal particles having a composition different from the first metal particles are included. A content ratio of the first metal particles in the three-dimensional shaped article producing powder is higher than a content ratio of the second metal particles, and a reflectance of a peak wavelength component of the laser beam at 25° C. with respect to the first metal particles is smaller than a reflectance of a peak wavelength component of the laser beam at 25° C. with respect to the second metal particles.
