The paper offers a brief overview of existing 3D printers. Some of them are described in the process of printing out specific real properties. The point is made that the adoption of additive technologies opens up a new era of industrialization in the construction sector. The paper discusses some conventional indicators, which can be used as well to assess the efficiency and environmental safety of additive construction technologies.

The paper brings to the fore the prospects of using 3D printers in construction. Some of them are described in the context of resemblance to modern construction mechanisms. Additive construction technologies are reported to be currently used for adding on structural elements in low-rise and medium-rise buildings. At the same time, the authors argue that all theoretical prerequisites are in place for making multifunctional construction equipment, combining the functional capabilities of modern tower cranes and stationary concrete pumps, to put additive technologies into practice

The purpose of this article is to identify shortcomings in the construction of prefabricated buildings and structures on the basis of an analysis of a number of scientific publications of domestic and foreign scientists. Since not only buildings, but also structures can be prefabricated, it is proposed to use the term "fast erectable building systems" (BSS). It is noted that, despite the great advantages of the FSU, at the current stage of development they do not fully meet the requirements of reliability, energy efficiency, rationality and comfort, suitability for operation under any climatic conditions.
