(57) The invention relates to the construction materials industry, and more particularly to a method of manufacturing hollow geometrically complex construction products, the surface of which may be inclined at an angle of up to 180° relative to the vertical axis, which is performed by layered extrusion (3D printing). The technical result of the invention is that of preventing the buckling of a construction product. A method of 3D printing a hollow geometrically complex construction product in an open container comprises the following steps: a) applying a layer of a concrete mixture in a 3D printing process for forming a wall of a final product; b) filling with a ground plastic material the cavity formed by the inner surfaces of the concrete mixture layer, and/or the cavity formed between the outer surface of the concrete mixture layer and the inner surface of the open container; c) repeating steps a)-b) until the final product reaches the desired height; d) removing the ground plastic material from the cavities once the concrete mixture has hardened.
