A nozzle includes an ejection section and an acceleration section. A powder is configured to be ejected from the ejection section. The acceleration section is configured to allow the powder to circle around and is configured to accelerate the powder in a peripheral direction of the powder that circles around so as to transport the powder to an opening.

Nozzle and additive manufacturing apparatus

A gas-recycling device according to an embodiment includes a particle remover, a liquid remover, and a supplier. The particle remover brings a mist of liquid into contact with a gas which includes particles and is discharged from an apparatus, to remove the particles from the gas. The liquid remover removes the liquid from the gas having passed through the particle remover. The supplier supplies the gas to the apparatus.

Gas-recycling device, additive manufacturing apparatus, and additive manufacturing method

An additive manufacturing apparatus includes an operation unit, a first face, a mover, a supplier, and an irradiator. The operation unit includes a first part and a second part that cover a part of a supply region supplied with a powdery material and facing a first direction are aligned in a second direction, and includes a first opening extending between the first part and the second part in the first direction. The first face of the first part faces the second part, and is provided with a second opening. The mover moves the operation unit. The supply unit supplies an inert gas from the second opening to the first opening. The irradiator is spaced apart from the operation unit, and can emit an energy ray to the supply region through the first opening, and change a position with which the energy ray is irradiated.

Layered molding device

According to one embodiment, a material feeding device includes a feeding unit. The feeding unit includes an electrode unit electrically chargeable by application of voltage thereto and an insulating unit covering the electrode unit, the electrode unit being configured to attract and separate a material to and from a surface of the insulating unit by control of a charged state of the electrode unit.

Material feeding device, additive manufacturing apparatus, and material supplying method

A collimator includes a plurality of modules each of which has a grid formation and in each of which a plurality of walls are arranged in a row in a first direction and a second direction intersecting the first direction. The plurality of modules are connected together by one or more connecting parts.

Collimator, radiation detector, and radiation examination apparatus

A nozzle includes a magnetic field generating section and a body. The body includes an opening from which a powder is ejected. The magnetic field generating section includes a coil, the coil disposed to generate a magnetic field when applied with a current, the magnetic field causing the powder supplied to an inside of the body to swirl around.

An optical element includes first and second optical portions, and a first connection region. The first optical portion has first and second surfaces opposed each other. The first optical portion is light transmissive. The second optical portion has a third surface opposing the first surface and separated from the first surface, and a fourth surface on an opposite side to the third surface. The second optical portion is light transmissive. The first connection region connects at least a portion of an end of the first optical portion and at least a portion of an end of the second optical portion, and provides a seamless connection to the first and second optical portions. The first connection region is light transmissive. At least one of the first or second surfaces includes a portion slanted to a plane perpendicular to a first direction from the second optical portion toward the first optical portion.

Optical element and method for manufacturing the same

A nozzle of a layered object manufacturing apparatus according to embodiments includes a gas supply part and an exhaust part. The gas supply part includes a gas supply port through which gas is supplied. The exhaust part includes an exhaust port through which the gas is exhausted. The gas supply port and the exhaust port face each other and are spaced apart from each other.

Nozzle of layered object manufacturing apparatus, and layered object manufacturing apparatus

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.
