Although wire arc additive manufacturing (WAAM) has proven its capability of fulfilling demands of production of medium-to-large-scale components for automotive and allied sectors made up of aluminium, at present, WAAM cannot be applied as a fully fledged manufacturing process because of practical challenges such as under-matched mechanical properties, the presence of large residual stresses and mandatory post-deposition operation for the formed component. This paper is a review of WAAM technology including a brief of WAAM history, status, advantages and constraints of the WAAM field. A focus is provided including the efforts directed towards the reduction of porosity, tensile properties, microstructural investigations and other valuable advancements in the field of WAAM of aluminium.
