Abstract
A multi-laser system for additive manufacturing can be used inside a working chamber in an environment with an atmosphere of an inert gas, consisting of multiple laser sources and a plurality of optical and/or optical systems scanning necessary to generate and convey the electromagnetic radiation beams within the predetermined processing sectors in which it is possible to remove the fumes and/or pollutants deriving from the selective powder melting process as close as possible to the melted layer or layer and introduce in the same chamber the process gases necessary for the processing of powder bed fusion or powder bed in a localized manner.

A Multi-laser system for additive manufacturing comprising:
- a matrix of independent optical systems designed to convey the electromagnetic radiation beams in a predetermined area of a work surface, the matrix of independent optical systems capable of superimposing at 100% the electromagnetic radiation beams in the predetermined area of a work surface, the matrix of independent optical systems being connected to the upper surface of a machine tool;
- a work surface, designed to house a powder bed, operatively connected to a piston;
- and
- wherein a system for the aspiration of fumes and introduction of support gases is provided with a diffusive central element suitable for process gas in work sectors and two suction side elements designed to remove the fumes deriving from the process from the work sectors, the central diffusive element and the suction side elements operationally connected to a work plan.
