Claim 5:
6. The powder bed fusion apparatus according to claim 4, further comprising a second temperature measurement device that is provided so as to detect a temperature of the powder material stored in the first storage container, wherein
when the powder material in the second storage container is carried into the fabrication container, the evaluation unit evaluates the carrying of the powder material based on a comparison between a change in the temperature of the powder material stored in the first storage container detected by the second temperature measurement device and a second threshold value, and
when the evaluation unit indicates that the change in the temperature of the powder material stored in the first storage container is less than or equal to the second threshold value, the amount calculation unit increases an amount of the powder material to be carried into the fabrication container by moving the recoater from the first storage container side to the second storage container side or an amount of the powder material to be carried into the fabrication container by moving the recoater from the second storage container side to the first storage container side by a second predetermined amount from a second reference value.
