TSU scientists have developed a 3D printer that has no analogs. It allows printing ceramics that whose properties compete with those of high alloy steel non-ferrous metals and hard alloys. Now scientists have completed testing of the technology, thanks to which it will be possible to obtain three-dimensional products with a wide range of applications in energy, radioelectronics, mechanical engineering, the chemical, oil, and gas industries, and the defense sector.
According to Promahov, until now the main method was pressure die casting, which does not allow obtaining ceramic products with complex configuration. Currently, there are methods of 3D printing of complex geometries, but they allow obtaining porous products of low strength with the remains of adhesive materials.
The advantage of the work of TSU scientists is comprehensiveness: they not only work with the technology of printing products, but also synthesize materials for it. In particular, with the method of "solid flame" - self-propagating high-temperature synthesis (SHS) based on the exothermic combustion reaction, scientists obtained ceramic powders (carbides, nitrides and borides of metals).
The products obtained can be used as protective panels of space devices, separate parts of propulsion systems, substrates of microcircuits, and in other applications.
Vladimir Promahov emphasized that the TSU method for producing three-dimensional ceramic products using a 3D printer received a positive decision on granting a patent. Under the project, supported by a grant of the Russian Foundation for Basic Research, the research team from the Laboratory of High-Energy Systems and New Technologies, and Laboratory of High-Energy and Special Materials are planning to adapt the technology to a wide range of ceramics.
