Abstract: This invention quickly supplies a predetermined amount of powder from a hopper to a recoater. A powder supply apparatus includes, as its feature, a hopper, a powder spreader, a powder replenisher, and a pivoting unit. The hopper of the powder supply apparatus stores a powder. The powder spreader spreads the powder on a shaping surface. The powder replenisher of the powder supply apparatus is provided between the hopper and the powder spreader, and replenishes the powder spreader with a predetermined amount of powder. The pivoting unit of the powder supply apparatus causes the powder replenisher to pivot.

Abstract: A powder is spread in two directions, that is, the advancement and retraction directions of a powder recoater. The powder recoater according to this invention includes a hopper that stores a powder, and a cylindrical powder supplier that has a side surface close to or in contact with the bottom surface of the hopper and includes a supply path for the powder. The powder recoater according to this invention further includes a pivoting unit that causes the powder supplier to pivot. In the powder recoater according to this invention, the center axis of the supply path is displaced from the center axis of the powder supplier in the radial direction of the powder supplier.
