Challenges, New Approaches, and Potential Future Paths for Three-Dimensional Printing (3DP) in Building Project: A Reviews

The application of 3D printing technology in the industry represents a substantial advancement in addressing longstanding issues in construction: labor shortages, sustainability, and cost reduction. In addition, it facilitates the generation of complex forms while consuming less material. Less labor could reduce construction costs by 40% and the time needed to build a structure by 70%. Still, there are hurdles to widespread 3D printing, such as material requirements, quality management systems, and regulations. This study points to significant knowledge and technology gaps in material development, quality control, and compliance, which limit effective implementation. This stresses the demand for new construction materials and reliability standards for 3D-printed applications and structures. The research also investigates the novel development in material science, automation, and sustainability practices that augment the output of the 3D printed components. The study employs a systematic literature evaluation and case studies to formulate recommendations for surmounting current obstacles and advancing the practical deployment of 3D printing in buildings. The findings demonstrate the possibility of developing new adaptive systems that foster more sustainable and efficient methodologies, thereby providing a framework for executing this technological shift. They also summarize how construction professionals, researchers, and policymakers might apply these formulas.
