The close affinity between hand work and building processes is a main problem in Civil Engineering. It causes not only slowing down the speed of building, but increases additive spendings on some processes like finishing works too. Application of 3D-printers in this branch of building sector an solve some modern problems, and also allow bringing the sphere of building and construction to a new level. The purpose of the study was to find out the level of technical development of 3D-printers in building, their advantages and disadvantages and also their possible application for the prospects of activation in the building complex of the Russian Federation. The study was based on learning different versions of 3D-printers and their software. It showed that they were able to erect different buildings and substructures despite their entry-levels of technical development. There were described processes of generating STL-models of buildings and their following transformations into G-codes. Also 3D-printers were divided in accordance with their conditions into mobile, fast-printing, having different spatial operating methods and others. In article there were showed flexible performance capabilities of this equipment and sounded real building progress rates via the examples of printed houses in different countries. Based on the findings there were drawn some conclusions about technical and economic advantages of using 3D-printers in low rise buildings. There was a special attitude for the question of application 3D-printing in the building complex of the Russian Federation. Estimation of expansion of this technology was confirmed by the existing achievements in the market of the Russian Federation. The prospects of this technology were also confirmed by modern state policy of interest in researches of additive technologies.
