Abstract: Due to the issues of significant deformation and low accuracy when manufacturing inclined thin-walled parts using selective laser melting, this article is dedicated to the systematic study of the influence of thickness and inclination angle of such parts on their deformation characteristics. The problems associated with deformations and inaccuracies in the laser melting process significantly limit the potential use of this method in the production of complex and high-precision parts, such as components for aviation and space technologies. To address this, the article proposes a combination of numerical modeling and experimental validation, which allowed for obtaining accurate and reliable results. A detailed numerical analysis of the deformation behavior of thin-walled parts with varying thickness and inclination angle was carried out using specialized software. The modeling predicted the main deformation trends and identified key mechanisms influencing shape accuracy. An important outcome was the understanding of how changes in these parameters can affect the final shape of the part and its mechanical properties. To verify the reliability of these results, a series of precise laboratory experiments were conducted, demonstrating a high degree of agreement with the calculated data. These experiments helped identify additional factors that may influence the process accuracy and proposed methods for minimizing them. The research not only revealed specific mechanisms by which thickness and inclination angle affect the deformation of thin-walled parts, but also provided scientific foundations for optimizing selective laser melting technology. The findings allow for a significant improvement in the accuracy of manufacturing thin-walled parts and broaden their application in various industries, such as mechanical engineering, aviation, space, and other high-tech sectors where high precision and reliability are required.
