Over the last decade, 3D printing (formally known as Additive Manufacturing (AM)) has gained great importance in the industrial fields of aerospace and biomedical engineering. The potential of this innovative manufacturing technique resides in the freedom to create any geometrical form with no formal constraint, thereby reducing the amount of material waste while improving performance and outcome. The move towards automation in the construction industry has recently reached some important milestones, namely, the development of the first structures realized by means of robotic arms and 3D printing technology. Additive Manufacturing (AM) processes are nowadays adopted in the construction of structural elements using polymeric materials, concrete, and metals. The application of CAD-integrated software allows these AM processes to create free forms and new architectural shapes. Despite major research efforts devoted to the study of AM techniques in mechanical, aerospace, and biomedical engineering, there is still limited knowledge regarding the uses, applications, and impacts of 3D printed materials in relation to civil structures, both in terms of material properties and structural response.
