Beschreibung
Zusammenfassung:	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.
