TSU scientists will help reduce the cost 3D printing ceramic parts


TSU scientists are creating new materials for 3D printing ceramic products. They adapted nanopowders for additive technologies - aluminum and zirconium oxides, which are widely available on the market but used only for pressing and sintering at high temperatures. The physicists discovered how to make materials for 3D printing ceramic parts from these compounds that can be used in conditions of high mechanical loads and temperatures, for example, in space.

– Scientists around the world came to the conclusion that it is impossible to use ceramic nanopowders for those types of 3D printing using laser alloying, – says Vladimir Promakhov, an staff member of the TSU Laboratory of High-Energy Systems and New Technologies and head of the FabLab laboratory at Siberian Design Center. – The reason is that the physical properties of ceramics do not allow obtaining the qualitative structure of materials by fusing powders. Products of complex geometry with a given structure are obtained only by casting polymer-ceramic compositions into steel molds with further sintering in high-temperature furnaces. Despite all the advantages, the high cost of this method is a significant disadvantage.
