An assembly for rapid manufacturing of symmetrical objects by direct metal deposition is disclosed. A rotary stage provides rotational movement to an object supported by the stage around a central stage axis. Nozzles are spaced above the rotary stage for performing direct metal deposition for building an object supported by the stage. Each nozzle is independently moveable along a horizontal axis and independently pivotable, and combined, moveable along a vertical axis for providing symmetrical movement corresponding to a symmetrical deposition configuration of the object while the object is rotated around the central stage axis.

When a diameter of the circumscribed circle is O, a diameter of an inscribed circle inscribed to the outer edge portion is I, and the number of the corner portions is n (n is an odd number), a diameter ratio α, which is a ratio between the diameter O of the circumscribed circle and the diameter I of the inscribed circle, fulfills a predetermined condition.

A method for producing an additively-manufactured article includes: a step for feeding a powdered material onto a base metal, the powdered material being obtained by mixing a first powder containing a stellite alloy and a second powder containing tungsten carbide; a nd a step for irradiating the fed powdered material with a laser beam while weaving the lase r beam, and depositing a cladding layer, obtained by melting and solidifying at least the pow dered material, on the base metal. The step for depositing the cladding layer is performed such that 20≤A≤35, 2.2≤B≤2.9, and 5 mass%≤R2≤15 mass% are satisfied, where A is a laser heat input index, B is a powder feeding rate index, and R2 is the ratio of the second powder contained in the powdered material.

A laser machining device includes a laser light source, a spatial light modulator which includes a display unit, an objective lens, an image-transfer optical system, a camera and a controller. The controller executes first display processing and second display processing. According to first display processing, when the camera captures the image, the display unit displays a first phase pattern for adjusting a condensing position of laser light condensed by the objective lens to a first condensing position. According to second display processing, when the camera captures the image, the display unit displays a second phase pattern for adjusting the condensing position of the laser light condensed by the objective lens to a second condensing position different from the first condensing position in an irradiation direction of the laser light.

Disclosed embodiments include a gantry assembly that has (i) a moveable carriage with a laser head affixed thereto and (ii) two sides (moveable subassemblies) that are connected by a joining subassembly. One side of the gantry has two motors: (i) a first motor (x-axis motor) that moves the carriage along a first axis (x-axis) between the two sides of the gantry, and (ii) a second motor (y-axis motor) that moves the gantry along a second axis (y-axis) perpendicular to the first axis. In some embodiments, the gantry assembly also includes a drive shaft (or alternative drive mechanism) operated by the second motor (y-axis motor) to facilitate movement of the two sides of the gantry together along the second axis (y-axis).
