3D printing in construction is when companies or projects sequentially layer materials via computer-controlled processes to create three-dimensional shapes. 3D printers are useful for creating new structures on-site or manufacturing components off-site for later assembly. The printer receives dimensions from a software program and builds the
The traditional construction technology not only has environmental friendly problems such as noise and dust but also has resource-saving problems such as large template quantity and low construction accuracy. In addition, the traditional construction technology has an insurmountable technical bottleneck in the construction of special-shaped buildings. Building 3D printing technology can
The global 3D printing building construction market is expected to grow from $0.01 billion in 2021 to $0.02 billion in 2022 at a compound annual growth rate (CAGR) of 177.0%. The growth is mainly Innovation and disruptive technology bring new legal risks and implications. In the context of construction defects claims, 3D printers will expose manufacturers and developers to liability and In recent few years, significant improvement has been made in developing largescale 3D printer to accommodate the need of industrial-scale 3D printing. Cementitious materials that are compatible with 3D printing promote rapid application of this innovative technique in the construction field with advantages of cost effective, high efficiency, design flexibility and environmental friendly. This The desired concrete for 3D printing requires 4 Challenges of 3D printing in construction certain specifications that are different from traditional con- struction; therefore, new materials have to be used in con- The previous section discussed the several benefits of 3D struction, because of the new technology requirements [10]. printing in 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.
The adoption of 3D printing technology by the construction sector can address various challenges such as time-consuming and inefficient construction procedures, amongst others. Whilst 3D printing is still in its early stages, many scholars think that it presents new chances for establishing new trends that ultimately lead to cost-effective

The application of 3D printing in the manufacturing industry has become known for process automation, fastening the production cycle and cutting down on wastes from the production stream [9]. 3D printing is a production technology that enables the building up of a component in successive layers. The 3D printing technique is an extension of the

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
To avoid the printing of overly complex 3D structures with preformed patterns, we recently pursued a complementary approach by printing stem cells with organoid-forming capacity to form centimetre
Therefore, due to the importance of cementitious composites and automation in building and construction industry, this paper will present a comprehensive study over cement-based composites, 3D printing in construction industry, and 3D structural printing’s potential and challenges for future direction of construction industry. 2.
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. The technology of additive manufacturing, especially 3D concrete printing (3DCP), has been recently adopted in the construction industry as a viable alternative to traditional construction methods. Although the technology offers a wide variety of structural, economic, and environmental benefits, it is still restricted in use due to certain limitations that are still under research.
