Abstract: A three-dimensional shaped object using a plurality of materials can be shaped, and replenishment of the materials is implemented during shaping without stopping an apparatus. A three-dimensional laminating and shaping apparatus includes a shaping chamber in which a three-dimensional laminated and shaped object is shaped, at least two material spreaders that are provided in the shaping chamber and spread materials of the three-dimensional laminated and shaped object, at least two material suppliers that supply the materials to the material spreaders, a controller that controls movements of the material spreaders and the material suppliers, and a beam irradiator that irradiates the materials with a beam. The material spreaders and the material suppliers are respectively paired, and the controller controls the movements of the material spreaders and the material suppliers so that each of the material spreaders is supplied, at a predetermined timing, with the material from a paired one of the material suppliers.

Abstract: In a three-dimensional laminating and shaping apparatus, a material is quantitatively spread without clogging a supply port with the material. The three-dimensional laminating and shaping apparatus includes a material spreader that spreads a material of a three-dimensional laminated and shaped object on a spread surface, and includes at least one tapered portion in which a diameter decreases from an upstream side to a downstream side. The three-dimensional laminating and shaping apparatus also includes at least one vibration ball that is arranged in the tapered portion of the material spreader and vibrates, and a vibration controller that controls vibration of the vibration ball.

Abstract: A recoater that is two-dimensionally driven is cooled by a simple structure. A three-dimensional laminating and shaping apparatus includes at least one material spreader that spreads a material of a three-dimensional laminated and shaped object, a temperature measurer that measures a temperature of the material spreader, at least one cooler that cools the material spreader and is provided at a standby position at which the material spreader stands by while the material is not spread, and a controller that controls the material spreader. The controller moves the material spreader to the standby position to bring the material spreader and the cooler into contact with each other.
