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.

System and method for adding material to a determined surface of a workpiece by means of a laser beam directed by a laser scanning head and lateral powder injection

The present disclosure relates to a shaping device for light rays of a laser beam that cross it, wherein the shaping device is formed by a conduit including an entry orifice, an exit orifice, and an internal wall, achieved by one or a plurality of facets adapted to reorient by at least one reflection at least a part of the rays of the crossing beam.
