Breaking the boundaries of traditional manufacturing, 3D concrete printing (3DCP) has revolutionised industries with its ability to turn digital designs into physical realities. This technology, particularly in concrete applications, involves depositing materials layer by layer using robotic systems or gantry setups controlled by digital 3D models. Unlike traditional construction methods, 3D printing offers benefits such as reduced material waste, a faster construction timeline, and the ability to create complex structures easily. This paper explores key recent advancements in 3D printing technology, emphasising materials, processes, and application innovations. In addition, the properties of concrete mixtures exhibit improved flowability, rapid setting time, and high strength, making them ideal for precise layering during printing. Alkali-activated concrete/geopolymers, made from agro-industrial byproducts, are eco-friendly, durable, and strong, offering a sustainable alternative to traditional materials. Fibre-reinforced materials, including steel, glass, basalt, nylon, and polypropylene, enhance tensile strength and durability. Binder jetting powders, including gypsum-based or sand-based powders combined with binders, are utilised for large-scale architectural components. Composite materials that combine cementitious and polymeric properties are also developed to optimise strength, flexibility, and thermal performance. This paper expands on previous research by investigating bio-cement and recycled aggregates, which contribute to sustainable construction and offer self-healing properties. Integrating 3D printing with technologies like Building Information Modelling (BIM) has transformed how construction projects are planned and executed. BIM allows for real-time updates to structural models, improving coordination between digital designs and robotic systems. The study includes several case studies to illustrate the potential of 3DCP. Several case studies are included in the study to demonstrate 3DCP’s potential. The practical application of this technology is demonstrated by projects like Saudi Arabia’s Vision 2030 housing projects, Habitat for Humanity’s affordable 3D-printed homes, and Dubai’s “Office of the Future.” These projects show how 3D printing may reduce costs, minimise waste, and speed up construction schedules without affecting quality. This study delves deeper into the advancements in technology and materials that had a role in the eventual success of these undertakings. 3D printing offers many advantages, but there are also some disadvantages when it comes to the construction business. We must address issues such as varying material quality, inadequate layer bonding, and the absence of standardised design guidelines to ensure integrity. Furthermore, its broad adoption is constrained by the high initial equipment costs and regulatory barriers, particularly in developing nations. Implementing government laws and incentives to promote the use of AI and sensor-like technologies similar to the Internet of Things (IoT) for real-time quality monitoring is one of the techniques mentioned in this review. Innovative components such as bio-cement and localised methods of 3D printing adaption are also being considered. These discoveries resolve problems with 3DCP scalability and connection with BIM and RM (Robotic Modelling). By addressing material discrepancies and regulatory challenges, suggesting AI integration, and securing governmental support, a clear pathway for advancing 3D printing technology paves the way for a more sustainable and efficient construction industry.
