    • The three-dimensional object building apparatus includes a powder delivering unit that delivers a powder on an object building area, a powder flattening device that flattens the powder delivered from the powder delivering unit to form a powder layer, and a light beam radiating unit that is disposed above the object building area and radiates a light beam on the powder layer to sinter or melt solidify the powder for building an object. The three-dimensional object building apparatus also includes a transferring mechanism that moves the light beam radiating unit in three-dimensional directions, and a shroud that moves integrally with the light beam radiating unit and surrounds a space above an area of the powder layer that is smaller than the object building area around a radiation of the light beam. The powder delivering unit and the powder flattening device move integrally with the light beam radiating unit.
    • 三维物体建造装置包括:粉末输送单元,其在物体建筑物区域上输送粉末;平坦化从粉末输送单元输送的粉末形成粉末层的粉末压平装置;以及光束辐射单元, 设置在物体建筑物的上方,并将光束辐射到粉末层上,以烧结或熔化固化用于建筑物体的粉末。 三维物体建造装置还包括使光束照射单元沿三维方向移动的传送机构和与光束照射单元一体移动并且围绕粉末层的区域上方的空间的护罩 小于对象建筑物周围辐射的光束。 粉末输送单元和粉末压平装置与光束辐射单元一体移动。
