A processing system includes: a processing apparatus for processing an object; a rotation apparatus for rotating a holding part holding the object; a movement apparatus for moving at least one of the processing apparatus and the holding part; a measurement apparatus for measuring at least a part of the object held by the holding part; and a control apparatus for controlling the movement apparatus and the rotation apparatus based on a measured result by the measurement apparatus to rotate the holding part and to move at least one of the processing apparatus and the holding part

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 three-dimensional additive manufacturing device appropriately detects a manufacturing abnormality. The three-dimensional additive manufacturing device includes a powder supply unit that supplies powder, a light irradiation unit that irradiates the powder with a light beam to melt and harden the powder to manufacture a layered structure, an imaging unit that captures an image of a manufacturing site including a molten pool formed of a molten powder, a result acquisition unit that acquires a determination result as to whether manufacturing of the layered structure is abnormal by inputting the image to a learning model, and an information output unit that outputs information based on the determination result. The learning model is obtained by machine-learning a correspondence relationship between an image of the manufacturing site at the time of abnormality and an abnormality type of the image, and is used for determining whether the manufacturing of the layered structure is abnormal.

The present disclosure relates to a system for performing an Additive Manufacturing (AM) fabrication process on a powdered material, deposited as a powder bed and forming a substrate. The system makes use of a laser for generating a laser beam, and an optical subsystem. The optical subsystem is configured to receive the laser beam and to generate an optical signal comprised of electromagnetic radiation sufficient to melt or sinter the powdered material. The optical subsystem uses a digitally controlled mask configured to pattern the optical signal as needed to melt select portions of a layer of the powdered material to form a layer of a 3D part. A power supply and at least one processor are also included for generating a plurality of different power density levels selectable based on a specific material composition, absorptivity and diameter of the powder particles, and a known thickness of the powder bed. The powdered material is used to form the 3D part in a sequential layer-by-layer process.

A build system is provided with: a build apparatus that performs a build process for forming a build object by supplying build materials to an irradiation area of an energy beam from a supply system while irradiating a target object with the energy beam from an irradiation system; and a change apparatus that is configured to change a relative position between the energy beam and the target object, wherein the build system differentiates a condition of the build process that is performed at a first area of the target object and a condition of the build process that is performed at a second area of the target object.

A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.
