Provided is a technique for fabricating a powder material bedded in advance using a DED nozzle. According to one embodiment, there is provided an AM apparatus for manufacturing a fabricated object. The AM apparatus includes a DED nozzle. The DED nozzle includes: a DED nozzle main body; a laser port disposed at a distal end of the DED nozzle main body and for emitting a laser beam, and a laser passage configured to communicate with the laser port and for allowing the laser beam to pass through the DED nozzle main body; and a powder port disposed at the distal end of the DED nozzle main body and for emitting a powder material, and a powder passage configured to communicate with the powder port and for allowing the powder material to pass through the DED nozzle main body. The AM apparatus further includes a cover configured to surround a peripheral area of the laser port and the powder port of the DED nozzle. The cover is configured to have an opened downstream side in an emission direction of the laser beam. The cover includes a gas supply passage for supplying a gas inside the cover. The gas supply passage is configured to be oriented so as to guide the gas toward the DED nozzle main body.

An apparatus and method of fabricating particles composed of metals, conducting polymers, semiconductors, and composites of such materials are provided. The method includes application of an editing tool, such as a laser, for patterning an editable structure that mounted on an electrically conductive substrate. Portions of the editable structure may be removed so as to allow electrodeposition.

A method of forming a cutting element for an earth-boring tool may include directing at least one energy beam at a surface of a volume of polycrystalline superabrasive material including interstitial material disposed in regions between inter-bonded grains of polycrystalline superabrasive material. The method includes ablating the interstitial material with the at least one energy beam such that at least a portion of the interstitial material is removed from a first region of the volume of polycrystalline superabrasive material without any substantial degradation of the inter-bonded grains of superabrasive material or of bonds thereof in the first region.

The invention relates to a device (100) for an additive manufacture. The device (100) comprises a laser device (110) for machining material using a laser beam (112), said laser device (110) being designed to deflect the laser beam (112) onto a machining region of a workpiece (10); at least one supply device (130) for a supply material, said supply device being designed to supply the supply material to the machining region; and an interferometer (140) which is designed to measure a distance to the workpiece (10) by means of an optical measuring beam (142).

The present disclosure relates to a system for performing an Additive Manufacturing (AM) fabrication process on a powdered material (PM) forming a substrate. The system uses a first optical subsystem to generate an optical signal comprised of electromagnetic (EM) radiation sufficient to melt or sinter a PM of the substrate. The first optical subsystem is controlled to generate a plurality of different power density levels, with a specific one being selected based on a specific PM forming a powder bed being used to form a 3D part. At least one processor controls the first optical subsystem and adjusts a power density level of the optical signal, taking into account a composition of the PM. A second optical subsystem receives the optical signal from the first optical subsystem and controls the optical signal to help facilitate melting of the PM in a layer-by-layer sequence of operations.
