Although intense research effort has been paid toward the mechanical characterization of WAAM-produced thin walls, little attention has been devoted to the investigation of multi-layered thick parts. These latter would indeed expand the application of WAAM for large-scale constructions requiring thicker cross-sections to withstand high loading conditions. The present work provides a comprehensive experimental investigation of mild steel WAAM thick plates from the fabrication to the mechanical and microstructural characterization. First, the fabrication process is presented in full details. From that, microstructural and mechanical characterization is described and discussed, showing a homogeneous microstructure with little influence on the mechanical response along the wall plate thickness, also considering different specimen orientations with respect to the printing directions. The results confirm good mechanical properties of the printed outcomes, in line with those of structural mild steels manufactured with conventional technologies. Little influence on the response along the thickness is reported, thus proving the required quality of WAAM thick parts for applications in the construction sector. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.9 2023 ENGINEERING, MANUFACTURING 29 / 68 = 0.426 2023 Q2 T2 AUTOMATION & CONTROL SYSTEMS 36 / 84 = 0.429 2023 Q2 T2 0.696 2023 Computer Science Applications 2023 Q2 Control and Systems Engineering 2023 Q2 Software 2023 Q2 Mechanical Engineering 2023 Q2 Industrial and Manufacturing Engineering 2023 Q2 5.7 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Arrè, Lidiana Tonelli, Lavinia Di Egidio, Gianluca Ceschini, Lorella Monzón, Ivan Laguía, Alberto Dieste, José Antonio Universidad de Zaragoza (orcid)0000-0001-7178-4285 Palermo, Michele 5002 515 Universidad de Zaragoza Dpto.
