Abstract:

The 3D printer technology of insulating walls, using the technology of one-stage polystyrene concrete laid with electric heating of the initial mixture is described. This technology test’s results, confirming the possibility of layer-by-layer molding of the insulated wall with the bead polystyrene’s filler mixture was subjected to electro thermal treatment directly in the working head of the 3D printer were carried out. Polystyrene swells, changing the thermal characteristics of the material and, at the same time, compacting the mixture, and the 3D printer forms a quick-hardening working layer of a wall, being built from the hot mixture that is losing its mobility. The technological features of molding a wall of one-stage polystyrene concrete by a 3D printer, the uniform distribution of polystyrene granules in it and its strength were investigated. The possibility of the proposed technology using in the construction industry was proved.
