Abstract: The paper discusses the use of 3D printing for slab construction, focusing on the quality and competitiveness of new structures. An innovative approach to the construction of horizontal load-bearing elements is proposed, using mortar mixes with partial replacement of cement with aleuropelite and the viscosity modifier methocaolin. The main attention is paid to the printing technology, which includes the use of a gantry 3D printer with a "mortar extruder" and the development of the design of rotatable slab segments. The article analyzes existing methods and approaches to 3D printing in construction, identifying the shortcomings of traditional technologies and the need to improve them to increase efficiency. The existing experience of printing beams and flat trusses using concrete mixtures is considered. Methods for calculating and evaluating the quality of 3D printed slabs, including a qualimetric methodology for assessing competitiveness compared to traditional slab types, are proposed as part of this work. The results show that the new technologies can provide higher quality and lower construction costs, making them competitive in the market. In addition, the use of 3D printing can significantly reduce construction time, which is particularly relevant in the context of increasing demand for housing. The use of automated processes reduces dependence on labor, which helps to solve the problem of a shortage of qualified specialists in the construction industry. It is also worth noting that the introduction of eco-friendly materials in 3D printing helps reduce the negative impact on the environment, making construction more sustainable and efficient.
