PURPOSE: To provide a device and a method for distributing powder in order to form a powder layer having a desired space thickness. CONSTITUTION: This device is provided with a drum 116, a mechanism 126 which moves the drum 116 from one end 110 of a target range 102 toward another end 112 and mechanisms 116-124 which rotate the drum. At this time, the direction of rotation of the drum 116 is made to be inverse to the moving direction of the drum 116. Dispensing of the powders is performed from an opening 108, a reversely rotating drum flattens a pile of the powders toward the another end 112 and the powder layer is formed behind the drum 116. |
