Abstract:

3-dimensional (3D) printing technology, a core technology of Industry 4.0, is increasingly being applied in the construction industry. Scientific research and deployment of this technology in the building industry have both significantly contributed to its widespread use. The aim of this research is to evaluate the material used in 3D printing technologies in the construction sector to understand its development and future research in the industry and scientific community. The evaluation included 74 research publications from the Web of Science database and 25 building applications from the construction sector. The VOSviewer and Bibliometrix package for R software were used to visualize the results of the bibliometric analysis graphically. The literature was examined and it was found that cement-based materials, polymer, concrete, recycled or waste materials, and new material mixtures are being investigated, with concrete receiving the most attention. The 25 3D-printed constructions were predominantly houses (76%), and these construction printing materials primarily used concrete (88%). 3D printing material design mixes must provide rheological properties such as printability, extrudability, and manufacturability. The properties of materials used in 3D printing, such as fire resistance, durability, thermal properties, and acoustics, are examined in very few studies. However, further research should characterize and improve the material properties associated with 3D printing buildings.
