Abstract: Controlled manufacturing system suitable for controlling a method for manufacturing, repairing or resurfacing a part by deposition of material under concentrated energy, said controlled manufacturing system comprising: means for obtaining a three-dimensional digital model of the part; means for generating a manufacturing file for the part, based on the three-dimensional digital model of said part, to define manufacturing parameters of an additive manufacturing machine, said manufacturing parameters being associated with manufacturing instructions; means for generating a control file for the part to define control parameters of a control effector, said control parameters being associated with control instructions; analysis means for carrying out an analysis of the manufacturing file and the control file in order to determine if the manufacturing parameters and the control parameters can coexist during the simultaneous application of the manufacturing parameters to the additive manufacturing machine and the

Abstract: Disclosed is a system for adding material by melting powder on a determined surface of a workpiece by means of a laser beam in order to construct a volume, the system comprising: -a laser beam emitting device, -a laser scanning head provided with at least two galvanometric mirrors and provided with a lens for focusing the reflected incident laser beam on the determined surface, the system comprising the laser scanning head being held stationary relative to the workpiece while the volume is constructed, -a powder injection device positioned laterally relative to the focused reflected incident laser beam in order to distribute the powder on the determined surface, -the powder is melted by the focused reflected incident laser beam emitted on the powder distributed on the determined surface.

Abstract: The invention relates to a device (100) for detecting the position of a laser beam (15) with a predetermined diameter and emitted by a laser of an additive manufacturing machine, said detection device (100) comprising an upper portion (102) comprising a scanning zone (108) of the laser beam (15), said scanning zone (108) comprising, at the centre thereof, a circular hole (111) with a diameter substantially equal to the diameter of the laser beam and with a predetermined position; the detection device (100) comprising a lower portion (103), the lower portion (103) comprising at least one sensor (114) for collecting a portion of the energy transmitted by the laser beam (15); so that when the laser beam (15) scans the scanning zone (108) from a plurality of positions, the sensor (114) collects a portion of the energy transmitted by the laser beam from each position, the portion of the transmitted energy being maximum when the laser beam (15) is aligned with the circular hole (111).

Abstract: Analysis system (310) for a powder jet of an additive manufacturing machine, said powder jet (21) comprising powder and gas, said analysis system (310) comprising a separation device (312), said separation device (312) comprising: —a separator element (326, 327) comprising a circular side wall (328) defining a cylinder and at least one separation wall (330) suitable for separating the inner volume of said separator element (326, 327) into n equal portions that are symmetric with respect to the axis of symmetry of the cylinder, said separator element (326, 327) being suitable for receiving an initial powder jet (21) at the centre of said separator element (326, 327), on said at least one separation wall (330), in order to separate the initial powder jet (21) into n powder jet portions; and —means for detecting the quantity of powder in each powder jet portion.
