Feasibility analysis on the application of 3D printing technology on municipal roads

3D printing technology is an emerging technology; it can be used in various fields and has successful cases in all areas. And at present, the widespread application of 3D printing technology in construction engineering is concrete pouring. In construction, the application of 3D printing technology greatly shortens the construction period and reduces the consumption of manpower and molds compared with traditional structure. However, due to various factors such as immature technology and material selection, most of these successful examples of buildings using 3D printing technology are middle and low-rise buildings. Because of the complexity of the construction project itself, then, we can try to show the advantages of 3D printing technology perfectly in other directions in the field of architecture. It is in road engineering, the primary material of our construction is all kinds of concrete, and the 3D printing technology of concrete in the whole field of the 3D printing technology has been relatively mature and can be widely used. Combining the characteristics of the construction technology, working procedure, and materials in the municipal road, the 3D printing technology can maximize the benefit ofroad engineering in the construction of the municipal road. © Published under licence by IOP Publishing Ltd.
