Abstract
Wire Laser Additive Manufacturing (WLAM) is a deposition technology that uses a focused source of activation energy and belongs to the group of Direct Energy Deposition (DED) processes. It is an advanced additive manufacturing method for metal parts, in which a metal wire is melted by a laser beam and deposited layer by layer along a pre-programmed path. This review covers key thematic areas: optimisation of process parameters, analysis of microstructure and mechanical properties for dominant materials, and advanced process monitoring systems. Synthesising the conclusions shows that control of heat input, active cooling, and the development of specific wire materials are the key directions for the further industrialisation of this technology.
