These studies include those that explored the effects of 3D printing on the construction industry, the effects of 3D printing on the acceptance of integrated delivery systems, and the effects of Show abstract. 3D concrete printing technology (3DCPT) is a growing field of research, in part motivated by attempts to improve current concrete fabricating methods. Compared with traditional Applicability of 3D Printing into Sri Lankan Construction Context and its Importance 6.1 Cost Perspective Since the Sri Lankan economy is enlisted and operates in a developing perspective, the construction industry alone plays a vital role where 6-9 % of the contribution is provided to the Nation GDP (Gross Domestic Product) of the country. Despite the advantages and potential use of 3D printing in the construction sector, various factors can prohibit this technology from being mainstream. Given below are a few challenges of 3D printing technology in the industry: High costs. The high cost is the major challenge in the 3D printing industry. 3D printing, also known as additive manufacturing (AM), is a rapidly developing manufacturing technology, has gradually become an emerging and crucial adjunctive tool in medicine, and is the preferred method for fabrication of organ models. 3D printing constructs complex functional 3D structures layer by layer from various materials, [5-7] and The main challenge for successful 3D concrete printing is the complex characteristic the materials should possess. The solutions that the 3D printing for building and construction technology xGFUX. Applicability of 3D Printing into Sri Lankan Construction Context and its Importance 6.1 Cost Perspective Since the Sri Lankan economy is enlisted and operates in a developing perspective, the construction industry alone plays a vital role where 6-9 % of the contribution is provided to the Nation GDP (Gross Domestic Product) of the country. A Children’s Castle in Minnesota, USA, was built by Total Kustom using 3 D printing in 2014. Current Challenges 3D printing in construction is a recent approach and possesses many limitations. Albeit the steadily growing number of researches and efforts in the field, 3D printing is still in its infancy. Additive manufacturing, also known as three-dimension printing (3DP), has the advantages of high building efficient, low labor cost and less construction wastes compared to traditional construction technology. 3D printed concrete is a special type of concrete, which can be deposited through a 3D printer layer by layer without any formwork support and vibration process. 3.1. Energy and Environmental Benefits of 3D-Priting in Construction The referred studies either discussed, analyzed, or substantiated a wide range of benefits of 3D-printing in construction such as reduced time, material use and cost as well as maximized quality, design performance, efficiency, and productivity. [5]. Additionally, 3D printing of building models opens new opportunities for adopting automation technologies at the construction site [6]. However, the efficiency of automated construction through 3D printing strongly depends on the mechanical properties of Citation: Guamán‐Rivera, R.; There has been a comprehensive body of research conducted to understand the recent advances, future prospects and challenges of large-scale adoption of 3D printing in construction projects.
