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.
