Abstract
There is provided a method of fabricating a three-dimensional object. The method includes supplying, flattening, and collecting. The supplying supplies, with a powder supplier, powder to a fabrication chamber. The fabrication chamber includes a fabrication stage to store powder and an outer edge portion outside the fabrication stage, the outer edge portion having one bottom surface. The flattening flattens, with a flattener, the powder supplied by the supplying. The collecting collects, with a powder collector, the powder having overflowed from the fabrication stage to the outer edge portion by the flattening into the fabrication stage.
