The presented book deals with the use of Wire Arc Additive Manufacturing (WAAM) as a means of stiffening and reinforcing free-form sheet metal as an application in facade. The main focus of the research is developing a methodology for welding ontop of pre-bent sheet metal; including digitizing of arbitrarily-formed sheet metal, developing of process-parameters for welding on thin sheet metal and generating force-responsive welding paths. The research is focused on singly-curved sheet metal profiles, and is concluded by the production of a number of small-scale prototypes which illustrate the potentials for reinforcing sheet metal using WAAM.
Structures and Architecture. A Viable Urban Perspective? contains extended abstracts of the research papers and prototype submissions presented at the Fifth International Conference on Structures and Architecture (ICSA2022, Aalborg, Denmark, 6-8 July 2022). The book (578 pages) also includes a USB with the full texts of the papers (1448 pages). The contributions on creative and scientific aspects in the conception and construction of structures as architecture, and on the role of advanced digital-, industrial- and craft -based technologies in this matter represent a critical blend of scientific, technical, and practical novelties in both fields. Hence, as part of the proceedings series Structures and Architecture, the volume adds to a continuous exploration and development of the synergetic potentials of the fields of Structures and Architecture. With each volume further challenging the conditions, problems, and potentials related to the art, practice, and theory of teaching, researching, designing, and building structures as vehicles towards a viable architecture of the urban environment. The volumes of the series appear once every three years, in tandem with the conferences organized by the International Association of Structures and Architecture and are intended for a global readership of researchers, practitioners, and students, including architects, structural and construction engineers, builders and building consultants, constructors, material suppliers, planners, urban designers, anthropologists, economists, sociologists, artists, product manufacturers, and other professionals involved in the design and realization of architectural, structural, and infrastructural projects.
We live in a time when 3D printing has matured from a hobbyist and prototyping tool to a technology with potential to disrupt entire industries in and around the built environment. The developments in additive manufacturing are transforming architecture and design no less than they impact engineering and construction. The book portrays the rapid advances in research and industrial processes that have paved the road for this upheaval. In five chapters that cover historical development, engineering aspects, the digital design process, interactions with other technologies and potential for functionalization through additive manufacturing, the editors have curated a text that illustrates how a complex network of actors inspires and influences each other to make thistechnological transformation possible. The book follows the trail of scientists who prove the technology's viability and documents design explorations, prototypes and entire buildings that are demonstrating their readiness for the commercial market.
This book presents wire arc additive manufacturing (WAAM), its variants, processing steps, and the mechanical and microstructural aspects of developed components, along with a logical sequence that provides a ready reference. Wire Arc Additive Manufacturing: Fundamental Sciences and Advances introduces the timeline and history of WAAM. It offers a critical review of WAAM, its variants, processing steps, and the mechanical and microstructural aspects of developed components. The book showcases the methods and practices that need to be followed to synchronise WAAM with other conventional metal additive manufacturing, as well as other conventional techniques. The process steps, equipment, and the different materials used are discussed in detail, along with the various process parameters and their optimisation to counter the challenges and defects. Applications, trends, and case studies are also included in the book. This book, aimed at providing a concrete reference for researchers, academics, and professionals, allows for a thorough understanding of the different concepts and intricacies of WAAM.
Additive Manufacturing (AM) is a process where components are created by continually adding material one layer at a time. Several benefits of "additive" manufacturing versus traditional "subtractive" machining processes include a reduction of material waste, ease of producing complex parts by reducing the amount of production steps, and the reduction of manufacturing lead-time. Metal based AM (also called metal 3D printing) technologies have been developing over the past three decades to simplify the manufacturing process of metal parts and assemblies. The aerospace, medical, and marine industries have begun to utilize AM technologies in production. A review of current maritime applications of AM is included. The Wire Arc Additive Manufacturing (WAAM) process, which uses Metal Inert Gas (MIG) welding, is demonstrated to analyze its potential application for maritime utilization. This report shows how the flexural yield strength of welded plates changes with different amounts of metal additive reinforcement. A standard three-point bending test was conducted to determine the difference in flexural yield strength and to observe material behavior. Finally, it is discussed that AM processes, such as WAAM, are still being developing but their potential in the maritime industry is clear.

This book shows the potential of Additive Manufacturing (AM) for the development of building envelopes: AM will change the way of designing facades, how we engineer and produce them. To achieve today’s demands from those future envelopes, we have to find new solutions. The term ‘AM Envelope’ (Additive Manufacturing Envelope) describes the transfer of this technology to the building envelope. Additive Fabrication is a building block that aids in developing the building envelope from a mere space enclosure to a dynamic building envelope. AM offers the opportunity to manufacture facades ‘just in time’. It is no longer necessary to store or produce large numbers of parts in advance. Initial investment for tooling can be avoided, as design improvements can be realized within the dataset of the AM part. AM is based on ‘tool-less’ production, all parts can be further developed with every new generation. The basic principle of AM opens a fascinating new world of engineering, no matter what applications can be found: to ‘design for function’ rather to ‘design for production’ turns our way of engineering of the last century upside down. A collection of AM applications therefore offers the outlook to our (built) future in combination with the acquired knowledge.
