Abstract
A device for manufacturing a layered object includes a container, a vibration unit, and an energy beam irradiation unit. The container includes a stage, a wall surrounding the stage, and a lid. The vibration unit vibrates raw material powder to planarize a face of the raw material powder supplied into the container. The energy beam irradiation unit irradiates part of the raw material powder with an energy beam to form part of the layered object. The lid presses the raw material powder when the vibration unit vibrates the raw material powder. A space is formed between the wall and the lid in the container when the lid is in contact with the raw material powder. The raw material powder is allowed to flow into the space.
