“…The high printing velocity required to fabricate largescale elements for structural applications induce some nonnegligible geometrical irregularities of the printed outcomes [10,[22][23][24]. Hence, additional considerations on the identification of the best printing strategy and set of process parameters is crucial to reduce these imperfections [25].…”

Current manufacturing techniques in the construction sector are slow, expensive and constrained in terms of architectural shapes. In other manufacturing sectors (such as automotive and aerospace) the use of automated construction systems significantly improved the safety, speed, quality and complexity of products. To realize real-scale structural elements for construction applications without ideally any geometrical constraints either in size or shape, the most suitable manufacturing solution for metallic elements is a directed energy deposition (DED) process referred to as wire-and-arc additive manufacturing (WAAM). The main advantage of WAAM relies on the possibility to create new shapes and forms following the breakthrough design tools for modern architecture as algorithm-aided design. At the same time, the printed part ensures high structural performances with reduced material use with respect to the conventional solution. The study presents a new approach called “blended” structural optimization, which blends topology optimization with basic principles of structural design and manufacturing constraints proper of WAAM technology, towards the realization of new efficient structural elements. The approach is applied to the case study of a I-type stainless steel beam on a multi-storey frame building. The approach could pave the way towards an efficient use of WAAM process to produce a new generation of structurally optimized elements for construction, with a more conscious use of the optimization tools and an efficient application of metal 3D printing.

“…A building material recipe should be created by getting the proper mixing ratios to accomplish 3D printing without shrinkage cracks and to be able to stack layers on top of one another without collapsing [17]. To improve the understanding and experience of this technology and to accurately adapt the process parameters to the needs of the construction sector, the construction industry needs to participate more actively in the research on metal 3D printing [18].…”

3D printing is an innovative construction technology that has a significant positive impact on the environment. It addresses issues on speed, labor costs, accuracy, and efficiency. This study aimed to know the trend of construction technology in onsite construction. Specifically, examine the history of 3d printing; discuss the 3D printing form of onsite construction; identify the innovation patterns of 3D printing; and explore the impacts of 3D printing technology. Although 3D printing has been around for a long time, the construction industry has just lately been neither affected nor disrupted. In some parts of the world, 3D printing has changed the way that industries operate. It enables the construction industry to swiftly create models and prototypes, enabling them to test and perfect new products more quickly. It is a fully automated, well-planned method that boosts output while lowering human error. The discussion shows some benefits of 3D printing including decreased costs and time, less environmental pollution, and a decline in accidents and fatalities on construction sites. 3D printing is automated, digitalized, and renewable which impacts regulatory agencies, culture and environment, economy, and society.

“…This makes AM versatile for mass production of structural and functional components [9]. These applications are mostly in industries such as medicine , construction [45][46][47][48][49][50][51][52][53] and aerospace product design [2,3,6,[54][55][56][57][58][59][60][61][62]. Despite the advantages and benefits of additive manufacturing, there are several challenges to adopting this technology.…”

Global perspective and African outlook on additive manufacturing research − an overview

et al. 2022

Additive manufacturing (AM) technologies and advances made globally in medicine, construction, aerospace, and energy sectors are discussed. The paper further explores the current state of AM innovation and development landscape in Africa as a late comer to this area of smart manufacturing. Peer-reviewed and published literature were retrieved from Scopus database from 2005 to 2021 and analysed. In Africa, out of 500 published articles, South Africa has the highest research throughput, whereas about two-thirds of the continent is not actively participating in this burgeoning field. The main AM techniques most widely used are selective laser melting, fused deposition modelling, and direct energy deposition. Globally, there is an interplay of computational (machine learning and mechanistic models) and experimental approaches to understanding the physical metallurgy of AM techniques and processes. Though this trend is consistent with global practices, Africa lags the world in AM technologies, a niche that could leapfrog the manufacturing sector. Thus, Africa need to foster collaborative partnership within and globally to become an active global player in this industry.
