  • Powder bed fusion apparatus with evaluation unit and multiple storage containers
    Patent number: 11865781
    Abstract: A powder bed fusion apparatus according to an embodiment includes: a fabrication container that is provided between first and second storage containers which heat a powder material stored therein to first and second predetermined temperatures, respectively, and that heats the powder material stored therein to a third predetermined temperature higher than the first and second predetermined temperatures, and lets the powder material be irradiated with a laser beam from a laser beam emission unit based on a model to be fabricated; and an evaluation unit that, when the powder material in the first storage container is carried into the fabrication container, evaluates the carrying based on a comparison between a threshold value and a change in the temperature of the powder material stored in the second storage container calculated based on the temperature detected by a temperature measurement device.
