3D Printing Technology and Future of Construction: A Review

Abstract

Abstract Historically characterised by its labour-intensive nature and low productivity, the construction industry is witnessing a technological revolution. Among these advancements, 3D printing stands out as a frontrunner, offering the potential to automate construction processes, reduce material waste, shorten project timelines, and mitigate risks associated with manual labour. This study explores the transformative capacity of large-scale 3D printing in construction, examining current progress, potential trajectories, and inherent limitations. Furthermore, it assesses the impact of expanded 3D printing adoption on the construction labour market. Our findings highlight 3D printing’s potential to significantly diminish the need for manual labour, addressing labour shortages, particularly in countries reliant on immigrant labour forces. However, its effectiveness may vary in regions with competitive labour costs where manual labour remains prevalent. Integrating 3D printing in construction necessitates cultivating a specialised workforce with expertise in this innovative technology. In conclusion, this study underscores the transformative influence of 3D printing in construction, offering increased efficiency, reduced labour dependency, and solutions to industry challenges. Adapting 3D printing adoption to regional labour dynamics and workforce upskilling is essential for maximising its benefits. As the construction industry evolves, embracing 3D printing emerges as a pivotal factor in shaping its future landscape.
