FIELD: construction.
SUBSTANCE: invention relates to construction and is intended for decorative finishing of concrete and reinforced concrete products, namely, for obtaining graphic elements on a concrete surface. A method for creating volumetric images from building mixtures by 3D printing includes applying an image to a finished concrete surface pretreated by laser ablation by means of a building mixture, in at least one layer through an extruder. Moreover, the preparation by the method of laser ablation is carried out at the points of contact of the volumetric image with the surface of the concrete product.
EFFECT: improved quality indicators when obtaining graphic elements on a concrete surface.
