The article represents an attempt to outline the methodology for optimizing technological parameters and production processes in additive manufacturing of metallic components intended for aerospace structures. The author emphasizes the role of computational modeling and topology optimization as effective tools for weight reduction and structural improvement, while maintaining compliance with aviation safety standards. Considerable focus is also made on the domain of adaptive control of printing parameters, and the enhancement of quality assurance procedures. Furthermore, the article outlines the criteria for selecting aerospace components materials suitable for additive manufacturing and provides practical examples of successful industrial applications. The experiment implying manufacturing a modular block unit based on high-strength AlScMg powder using selective laser melting additive technology. Experimental studies demonstrated that using selective laser melting additive technology with appropriate parameters (feed rate, temperature) in the production of the modular block unit results in a reduction in the mass of the product. Properties that positively affect the quality of the resulting sample have been identified. Optimization of process parameters has been shown to improve the morphological properties of the product (porosity and roughness).
