Development of a technology for the production of aluminum castings using 3d printing of models and lost-was casting

Industrial development of the Republic of Kazakhstan requires accelerated formation of industries with high added value, capable of meeting domestic needs and increasing export potential. Despite the potential for innovative development, additive technologies for the production of metal products have limited application in traditional mechanical engineering industries due to the high cost of equipment (for example, 3D printers for metals) and, as a consequence, the high cost of production. This factor limits their use in serial production. Thus, the development and implementation of new casting technologies based on the integration of modern scientific achievements and advanced technical solutions is an important task for ensuring sustainable growth of high-tech and competitive industries in Kazakhstan. Development and implementation of technology for the production of aluminum castings of complex shapes using 3D printing of models and investment casting, which will reduce production costs, shorten manufacturing time and improve product quality for strategically important industries. The study used comparative analysis methods and experimental studies aimed at studying the mechanical properties of products manufactured using various technologies, as well as optimizing 3D printing parameters to achieve better product characteristics. The results showed that additive technologies provide high accuracy, allow you to create complex geometric shapes and reduce waste. However, to improve the mechanical properties of products, such as strength and wear resistance, it is necessary to optimize the extrusion parameters during 3D printing. The findings of the study confirm that the choice of technology depends on the specific conditions and requirements for the product. Additive technologies, despite the existing advantages, require further research to improve the properties of final products. The practical significance of the work is that the results of the study can help manufacturers choose the most efficient and cost-effective production methods, which in turn will lead to reduced costs and improved product quality, as well as improved environmental performance.
