Selective laser melting
Additive manufacturing (AM) is defined by ASTM as the 'process of joining materials to make objects, usually layer by layer, from 3D CAD data'. Additive processes include Selective Laser Melting (SLM), Laser Metal Deposition (LMD), Stereolithography, Fused Deposition Modelling (FDM) and 3D Inkjet Printing (3DP). Each technology is often distinguished by the raw materials used (including powder, wire, photosensitive liquid resins, thermoplastic filament, printing inks) or by the method of consolidation (including laser heating and melting, photo polymerisation, conduction heating, chemical reaction).
AM is seemingly opposite to subtractive manufacturing approaches that remove material to form the shape of a work piece. The traditional metal removal processes such as milling, turning, grinding, electrical discharge machining (EDM), fall into this category.
