Structures, Volume 44, October 2022, pp. 1506-15222352-0124https://doi.org/10.1016/j.istruc.2022.08.084https://dspace.lib.cranfield.ac.uk/handle/1826/18423This paper provides a review of the capabilities of WAAM for manufacturing steel components for use in the construction industry, with a focus on the structural stability and design of WAAM builds. Manufacturing techniques that can be used for WAAM construction are first discussed. This is followed by a detailed review of the material and geometric properties, and the resulting structural stability performance of WAAM steel structures to date. To exploit the advantage of WAAM in building free-form shapes, structural optimisation techniques suitable for WAAM construction are discussed. Lastly, conclusions and future research directions are provided.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Wire arc additive manufacturing (WAAM)Additive manufacturing (AM)Manufacturing parametersMaterial propertiesGeometryArticle
