A machine for additive manufacturing of components by sintering powder includes a framework, a working zone, at least two beam emission and control modules, and at least two actuators. Each module, which is structured to emit an energy beam and to control the energy beam, is mounted inside the framework and is provided with an emission source and an optical system for focusing the energy beam emitted from the source. Each module acts on the working zone to manufacture a same component. Each optical system is axially movable in translation with respect to the framework. The actuators are associated with the optical systems, respectively, and are arranged to adjust axial positions of the optical systems with respect to the working zone, the axial positions being adjustable independently of each other.
