Abstract

Among the additive layer manufacturing techniques for metals, those involving metal deposition,including laser cladding/Direct Energy Deposition (DED, with powder feeding) or Wire and ArcAdditive Manufacturing (WAAM, with wire feeding), exhibit several attractive features. For instance,one can mention high mass efficiency (50–80% for LMD, 100% for WAAM), large build rates (morethan 100 cm3/h), sound microstructures with a limited amount of porosities, and the ability to buildgraded or multimaterials. Even though corresponding processes have been developed a rather longtime ago, there is still an important demand for research work in various topics such as deposition ofnovel or graded materials, postprocessing, and wear behavior of deposited materials.The current Special Issue, including six contributions, aims at presenting recent and original workdedicated to all these aspects, with a more specific focus on coatings than on 3D structures.
