In this work, SiC–Ti₃AlC₂ and TiC–Ti₃AlC₂ composites produced by additive manufacturing are investigated. The issue of obtaining ceramic materials using additive manufacturing technologies is currently relevant, since not many modern additive technologies are suitable for working with ceramic materials. The study is devoted to the optimization of additive manufacturing parameters, as well as the study of the structure and properties of the resulting objects. The fused granules fabrication (FGF) method as one kind of the material extrusion additive manufacturing (MEAM) technology is used to obtain composite samples. The main advantage of the FGF technology is the ability to obtain high-quality samples from ceramic materials by additive manufacturing. Composites with different ratios between components and different powder/polymer ratios are investigated. The technological features of the additive formation of composites are investigated, as well as their structure and properties. The optimal sintering temperature to form the best mechanical properties for both composites is 1300 °C. The composites have a regulatable porosity. Ti₃AlC₂ content, sintering temperature, and polymer content in the feedstock are the main parameters that regulate the porosity of FGF samples.

In the present study, composites Cu–Ti₃SiC₂ were obtained via extrusion-based additive manufacturing technology. The composite was characterized in terms of its structure, mechanical properties, and tribological properties. The use of a low-energy additive manufacturing technique allows for the avoidance of the decomposition of the MAX phase while obtaining bulk samples. The optimal composition of 50 vol.% of Ti₃SiC₂ and 50 vol.% of Cu was selected based on the flow rate of feedstock melt and the density of the samples. The resulting composite exhibited a dense copper matrix with Ti₃SiC₂ and TiC inclusions, achieving 97% density and 62% IACS electrical conductivity. Tribological tests under varying loads, speeds, and temperatures demonstrated that increasing the load and speed increased the coefficient of friction and the wear rate, while higher temperatures reduced friction due to surface oxidation.
