Systems and methods are provided for controlling additive manufacturing material deposition using a magnetic field. A system may include a build surface; a material depositor through which a magnetically responsive material is deposited on the build surface; an energy source; and a magnet set. The magnet set applies the magnetic field to the build surface and/or to the material depositor. The magnetic field is configured to attract the magnetically responsive material while the energy source melts the magnetically responsive material.

A three-dimensional deposition device includes a deposition head provided with a powder jetting port and a light beam irradiation port to form a deposited body by the powder being melted and solidified; a shape measurement unit that measures a shape of the deposited body; a deposited body cooling unit that jets cooling gas to the deposited body to cool the deposited body; and a control unit. The control unit causes the shape measurement unit to measure the shape of the deposited body, determines whether to cool the deposited body based on a result of measuring the shape of the deposited body, and causes the deposited body cooling unit to jet the cooling gas to the deposited body to cool the deposited body in a case in which the cooling determination unit determines to cool the deposited body.

A composition of a nickel based alloy mixture which can be used for welding via especially liquid metal deposition or as a powder bed of an additive manufacturing method. A metallic powder mixture includes (in wt %): a cobalt (Co) or nickel (Ni) based super alloy with a content of 20% to 60%, a NiCoCrAlY-composition with a content of 70% to 30% and a metallic braze material with a content between 10% to 5%. The melting point of the braze material is at least 10K lower than the melting point of the nickel or cobalt based superalloy.

An additive manufacturing apparatus includes: a material supply unit that supplies a build material to a process area of an additive target surface; an irradiation unit that irradiates the process area with a laser beam that melts the build material; and a control device that controls the material supply unit and the irradiation unit for creating at least a part of an object using a dot-shaped bead, the dot-shaped bead being formed of the build material melted by radiation of the laser beam. The additive manufacturing apparatus can improve the shape accuracy of the object.

A laser processing apparatus may include: a laser generator configured to generate a laser beam; a stage configured to support a target object; at least one supply nozzle on the stage to eject an air toward the stage; a suction unit configured to inhale external air; and a suction structure on the stage and adjacent to the at least one supply nozzle. The suction structure may include a suction hole connected to the suction unit to inhale the external air. The suction structure may include an inclined surface in which the suction hole is defined. The suction structure may include a first surface adjacent to the supply nozzle, and an opening may be defined in a region of the first surface adjacent to a bottom surface. A distance between the inclined surface and the target object may be less than or equal to a height of the opening.

A laser processing method for laser processing of a workpiece made of a base material and a fiber reinforced composite material containing fibers having a thermal conductivity and a processing threshold higher than physical properties of glass fibers. The laser processing method includes a step of processing the workpiece by forming a plurality of through-holes extending through the workpiece by irradiating the workpiece with pulsed laser light from a processing head while relatively moving the workpiece and the processing head in a predetermined cutting direction. The pulsed laser light has a pulse width smaller than 1 ms and an energy density capable of forming each of the through-holes by a single pulse.

An optical head for a laser transmission welding apparatus comprising a housing with an end on the outlet side with respect to a laser beam and a ball mounted in the housing. The ball may comprise a material whose refractive index is higher than the refractive index of quartz glass.

A laser marking system for marking a product comprising a laser source for providing a laser beam, a marking head for projecting the laser beam on to the product, a housing comprising an extraction device configured to generate a flow of extraction fluid for extracting matter generated by an interaction between the laser beam and the product, and a controller for controlling the laser source and the marking head. The laser marking system further comprises an umbilical assembly connecting the housing to the marking head.

The present invention is a laser processing device wherein adhesion of fumes to a lens can be effectively avoided. The laser processing device is provided with a laser scanner provided with protective glass on a laser output opening, and a cylindrical member having a through path through which the laser output via the protective glass passes formed on the center side in the direction of the radius. A cylindrically shaped filter is disposed on an inside wall part of the cylindrical member facing the through path. The cylindrical member discharges a gas into the through path from the filter.

A component and method of forming a component are disclosed. The component includes a cast alloy section and an additive manufacturing section secured to the cast alloy section. Both the cast alloy section and the additive manufacturing section form at least a portion of an outer surface of the component. The method of forming a component includes removing a portion of an existing component, the removing of the portion forming an open section in the existing component, forming an article through an additive manufacturing technique, the article having a shape and geometry arranged and disposed to fill the open section in the existing component, and securing the article within the open section of the existing component to form the component. Another method includes directly depositing a material, by an additive manufacturing technique, over a portion of the existing component.
