Relevance and advantages of modern additive manufacturing for mechanical engineering of Republic of Kazakhstan

Abstract

The article discusses current problems in the machinery industry of the Republic of Kazakhstan, analyzes data on import and export indicators of mechanical engineering products by sectors, and provides possible solutions to these problems – the implementation and development of additive manufacturing, according to the author. The advantages and disadvantages of additive technologies were highlighted, requiring further research and experiments to minimize or eliminate limitations. The latest developments and most advanced 3D printing technologies were also considered, including machine models that combine 3D printing and post-processing in one system. The L-WAAM technology, digital twins, and ultrasound-based 3D printing were discussed, as well as innovations in materials science resulting from the development of 3D printing. The article also provided an overview of scientists and institutions conducting research in this field, such as model qualification and certification of additive manufacturing, material selection, etc., as well as projects developed by companies to improve technologies in all areas, such as the development of the process itself, a digital platform, and an integrated L-WAAM cell.
