One of the promising directions is the investigation of compounds in the Cu-Sn-S and Cu-Sb-S systems, which combine environmental safety, chemical stability, and the possibility of being synthesized at low temperatures. Although these materials are already widely used, improving their properties remains a challenging task that requires the study and development of new compounds. Within the framework of this work, nanoparticles of Cu2Mn0.3Zn0.7SnS4 and tetrahedrite materials Cu12Sb4S13 alloyed with Ni, Ti, Sn, and Zn were obtained, which made it possible to investigate the effect of dopants on the structural, optical, and electrical properties. The materials demonstrated structural stability and suitability for forming functional layers in the form of ink suspensions. Special attention was paid to the creation of chemically stable inks based on nanopowders and their use for film formation using a modified 3D printer with a dual extrusion system, which opens up possibilities for producing multilayer structures without the use of vacuum technologies. Studies of alloyed tetrahedrites showed their potential for improving the efficiency of thermoelectric converters. The prospects of these materials are determined by their stability under extreme conditions, including high temperatures and chemically active environments, as well as their suitability for creating multifunctional devices based on heterojunctions. The obtained results contribute to expanding knowledge about the physicochemical properties of nanomaterials and form the basis for the development of new functional devices in solar energy, flexible electronics, and sensor systems.
