A process for recycling metallic materials, for providing raw materials for additive manufacturing, which includes the steps of: a) finding a plurality of materials to be recycled; b) identifying the chemical composition of the materials to be recycled; c) separating the materials to be recycled according to their chemical composition; d) selecting two or more materials to be recycled with different chemical compositions; e) introducing the selected materials to be recycled in a crucible; f) melting the selected materials to be recycled so as to form a mixture; g) checking whether the chemical composition of the mixture is substantially identical to that of a target material for additive manufacturing; h) extracting the mixture from the crucible if the outcome of the checking step g) is positive, or selecting and introducing additional materials to be recycled into the crucible if the outcome of the checking step g) is negative; i) producing the target material for additive manufacturing.
