“…DLP creates 3D models that are more robust and have a higher resolution. It also requires less material, which reduces expenses and waste (Alzarrad and Elhouar, 2019). For constructing a single layer of a 3D object by spatially controlled solidification using a projector light, the digital light processing (DLP) technology employing photocurable resins is fascinating (either UV or white light).…”

3D printing has been popular in the manufacturing industry as a means of automating processes, speeding up production, and reducing waste. It is frequently seen as a relatively new technology, even though it has been in use for more than three decades. This article aims to analyse 3D printing awareness in an emerging economy towards sustainability in the construction industry. A survey research design was used to obtain primary data from the respondents using structured questionnaires. The sample frame for the research survey comprises professionals in construction and consultancy firms such as architects, quantity surveyors, projects managers, and engineers. Mean item score, standard deviation, and factor analysis were used to analyse the data. The findings from this study show that majority of the professionals acknowledged that they were aware of the existence of 3D printing, but most of them attested that they had not utilized this technology before the survey. The study reveals that the professionals in the construction industry of the emerging economy have low awareness of 3D printing technology, therefore its practices in the construction industry of the study area are significantly low. More awareness of 3D printing technology should be raised by bodies shouldered with management and regulation of the construction industry to increase professionals' awareness and enlighten them on the benefits of adopting the technology towards sustainable construction.

“…As technology has progressed, 3D printing has expanded to accommodate construction products other than ceramic in recent years. In construction projects, 3D printers can currently produce plastic and nylon components such as plug fixtures, window frame fixtures, and plumbing fittings (Alzarrad and Elhouar, 2019).…”

“…The research methods for the 3D printing construction studies were analysed, and the results showed that around 32% of the publications are review articles that were performed in a systematic way. Scholars use this method to synthesise and interpret past research [73] to present the organised history of a specific topic [56] and to deliver new ideas for current conditions. For example, by overviewing recent attempts at applying 3D printing technology, Alzarrad and Elhouar [56] elucidated the sector's successes and challenges.…”

With the development of new construction technology, increasing attention is being paid to 3D printing due to its construction efficiency as well as its sustainability. Numerous researchers have determined its benefits in cost reduction, resource savings, safety assurance, etc. Although various advantages have been identified, there are limitations and challenges in technology implementation. Especially since it is a new construction method, 3D printing construction projects will have a very different supply chain compared to traditional projects. As part of a research programme investigating the 3D printing construction supply chain in a New Zealand context, this study systematically analysed the research about 3D printing adoption and supply chain challenges in the construction sector. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was adopted as the guideline for literature selection. PRISMA is designed to assist researchers in reporting the review research focus and methodology, and examining the findings from published literature. NVivo was then adopted to code and analyse the selected publications to gather the data necessary for our study. The literature was analysed from the perspectives of the research focus, research methods, and findings. Studies about 3D printing implementation, benefits and barriers, as well as its significance are also analysed. As a result, this research found existing research gaps, including the fragmented situation of management-related research in the 3D printing construction sector, insufficient research in top management for 3D printing construction implementation, and changes to supply chain management practices in 3D printing construction projects. A decision support system demo for supply chain management is drafted in this paper, which requires further study. The research outcome highlighted the existing studies in 3D printing construction implementation and supply chain, and initiated a research topic on supply chain decision making. The result contributes to the theoretical and practical development of 3D printing technology in the construction industry. This review paper also inspires future studies on supply chain frameworks and theoretical models.

“…AI could help robots to perform repetitive tasks more efficiently than their human counterparts, such as pouring concrete, bricklaying, welding, and demolition, etc. [25]. This releases up human workers for other construction activities and reduces the overall time required to complete the project.…”

The late Stephen Hawking was reported to have said, "Computers will overtake humans with AI within the next 100 years. When that happens, we need to make sure the computers have goals aligned with ours." This statement is frightening to most, as very few people may like the idea of seeing computers take over the world. However, what can be more frightening is for those few people who like the idea to also make use of Hawking's suggestion and find a way to make sure the computers have goals that are strictly aligned with only theirs. There is a distinguishable apprehension among people of the role AI is set to play in the future of humanity, and this apprehension is transcending disciplinary boundaries. In the particular fields related to construction, there seems to be a genuine interest in integrating AI in each phase of a project to improve quality, enhance safety, and reduce costs, but this interest is countered by a legitimate concern that many types of jobs would be lost to AI-enhanced machines. In this paper, the authors tried to shed some light on how AI might change the face of the construction industry. The authors, spanning generations and disciplines in the industry, tried to answer the question "will AI take over the construction industry?" each from their own perspective including architectural, structural, and construction management. A synopsis of the status of the application of AI in construction and related fields is first provided, and then the authors offer their individual views with respect to how they expect AI to affect their side of the industry. This paper is an effort to gain insights into the perceptions of current and future construction related professionals of the role of AI and the impact it may have on the industry.
