“…Depending on the workpiece, this process is supplemented every 20 -40 layers by a tactile measurement (TouchSense) of the current workpiece height to examine the layer height and make any necessary adjustments. This procedure has already proven successful in the manufacturing of more complex column geometries in shorter layer intervals [8]. In addition, the welding data is recorded for each layer and a layer image is created for each structure.…”

Wire Arc Additive Manufacturing (WAAM) is a robot‐controlled welding process used to build up three‐dimensional structures in steel. Like other Additive Manufacturing (AM) technologies, WAAM allows for geometrically‐complex structures to be manufactured which may be unfeasible using conventional methods. Over recent years, WAAM has also gained prominence in the fields of architecture and civil engineering, with applications ranging from fully‐printed steel bridges to individualized steel components. This paper presents the additive manufacturing process of large‐scale applications, focusing on steel columns with circular hollow cross‐sections (CHS). The paper highlights the specific features of the necessary welding and process parameters before the manufacturing process is described in detail. Digital models and welding trajectories are generated with Parametric Robot Programming (PRP) and serve the robot‐controlled printing process. The AM itself is monitored by multiple process‐control checks giving information about resulting weld thicknesses, heights and welding errors influencing the manufacturing strategy of the CHS columns. To be able to make a closing statement about the load‐bearing capacity of the WAAM‐manufactured CHS, final load tests on (stub) columns are carried out.

“…However, there is a significant overlap between papers covering topics represented in this and the other two clusters. For example, the impact of AM technologies on the design process can be observed in educational settings [44,45] and the construction industry [19,23,26,[51][52][53]. Another central theme is the design and fabrication of large-scale concrete structures.…”

3D Printing Technologies in Architectural Design and Construction: A Systematic Literature Review

et al. 2022

The proliferation of digital technologies considerably changed the field of architecture. Digital fabrication pushes architecture into an unexpected new domain of previously unachievable complexity, detail, and materiality. Understanding these technologies’ impact can help direct future research, innovate design and construction processes, and improve the education of future professionals. However, comprehensive reviews offering a holistic perspective on the effects of 3D printing technologies on architecture are limited. Therefore, this study aims to provide a systematic review of state-of-the-art research on 3D printing technologies in architectural design and construction. The review was performed using three major databases, and selected peer-reviewed journal articles published in the last ten-year period were included in quantitative and qualitative analyses. Using bibliometric analysis, the research progress is summarized through the identified trend of the annual number of articles, prominent authors and co-authorship network, and key topics in the literature organized in three clusters. Further, content analysis of selected articles enabled coding cluster themes. Moreover, the analysis differentiated two categories of 3D printing technologies based on the scale of the system, elaborating their peculiarities in terms of materials, methods, and applications. Finally, challenges and promising directions for future work and research challenges are discussed.

Wire and Arc Additive Manufacturing (WAAM) became a significant research field in structural engineering over the past years. It offers the opportunity to apply material fast and precisely, following the load path, inducing effective material consumption. Considering free‐formed sheet‐metal façades, to date large thicknesses are necessary to maintain the final shape and load‐bearing capacity that however causes high material consumption and costs during the construction processes. Hence, WAAM could be an opportunity to reduce the amount of mild steel used for free‐form façades. As part of a research project at TU Darmstadt, 1 mm thick free‐form sheet‐metal façades elements have been manufactured using WAAM. Due to precisely welded lattice structures, placed on the backside of the metal sheet, the reinforcement will be ensured. Wide studies on welding parameters focused on a stable process without damaging the later frontside of the façade panel and on process optimization. In addition, material properties of the welding material have been determined to check its usability in façade construction.
