This paper examines the advantages and difficulties linked to the incorporation of 3D-PT (3D printing technology) in the construction sector. There are several advantages to consider, such as improved constructability, sustainability, and design flexibility. 3D printing enables the production of complex architectural components with great accuracy and minimal material wastage, effectively tackling concerns like scarcity of labour and expensive materials. In addition, the incorporation of novel printable materials such as geopolymer concrete and recycled plastics plays a role in promoting sustainable building practice. Nevertheless, there are several challenges that arise with the use of 3D printing in the construction industry, several problems that need to be overcome, including material limitations, regulatory hurdles, and the substantial initial investment needed for equipment and training. It is necessary to address technical issues regarding structural integrity, process parameters, and the development of appropriate construction materials. Despite the obstacles, ongoing progress in technology and regulatory frameworks might enable wider acceptance of 3D printing in construction. This, in turn, could encourage inventive and environmental friendly building methods.
