This article studies the efficiency of new technology – concrete 3D printer. The creators of this equipment argue that it can save significant amount of funds, when used for building construction. This research looks into how 3D printer can save time needed for building frame construction and how it may affect the total construction cost. In this article you can see the results of calculation of labor and material costs for two types of houses: printed with a 3D printer and made of aircrete blocks. Moreover, the percentage of profit, based on potential time saved and the total cost of a single-story building were calculated. As a result of the research, it was concluded that 3D printers will be beneficial for construction companies engaged in large-scale low-rise construction.
