A process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies, such as traditional machining (ASTM).

From the tests performed, the mechanical properties achieved were largely in accordance with normal wrought product forms, such as bars, plates, sheets and tubes in the solution annealed and mildly cold worked conditions. All of the test results conformed to the requirements of relevant international product standards for comparative products, with subtle variations in typical composition and mechanical properties. The results were very encouraging in the context of the project and demonstrate that current selective laser melting techniques, applied to suitable materials present a valid technology for the production of components of satisfactory quality and integrity.
