Today, layer-by-layer printing of enclosing structures with a 3D printer is the formation of a permanent formwork from a cement-sand mixture, followed by concreting and thermal insulation of the structure using standard technologies and widespread use of manual labor. Despite the use of robotization, 3D printing is only partially involved in the construction process and does not solve the issue of increasing labor productivity. This, and other disadvantages, hinders its widespread use in construction. 3D printing with one-stage polystyrene concrete is devoid of many traditional printing disadvantages, which allows forming a layer of heat-insulating and structural material over the entire wall width in one pass during the construction process. It was possible to overcome the inhomogeneity of a wall thermal conductivity due to the “cold bridges”, lower layers spread that did not have time to grab and ability to work only at high temperatures. The approbation of the technology is demonstrated its feasibility and opportunities for improvement.
