Additive technologies are currently distributed in the construction sector in many countries worldwide. Analysis of data from previous studies have shown that the manufacturing process model and selection of the composition of the concrete mixture for additive technologies should correspond to various critical conditions that are directly related to the 3D printing methodology. In addition, they do not provide a clear picture of the complete cycle of manufacturing 3D-printed concrete products, especially non-standard configurations, from the development of composition to the printing of finished products. The purpose of this work is to model the process of manufacturing small-architectural-form products via 3D printing, use technogenic mineral formation (TMF) as part of concrete, as well as create a digital model for printing. As a result of the conducted research, a digital model to produce prototypes was created, a mixture composition for printing on a 3D printer was selected, and small-architectural-form products were produced. The optimal amount of filler to be replaced by industry-related mineral formation is 27%, which provides the required mobility of the mixture for 3D printing, preserves and even increases the strength characteristics (up to 13%). These results demonstrate the effectiveness of technology-related mineral formation to replace natural sand in the production of 3D-printed concrete products with complex configurations. They present good prospects in the construction industry for the creation of sustainable construction materials with positive environmental impacts, which may be of practical value to both researchers and manufacturers in the construction industry.
