Abstract
Additive manufacturing (hereinafter – en. AM) is a modern set of technologies that make it possible to quickly and qualitatively create products with a unique geometry that are impossible or difficult to produce by traditional production methods. Currently, researchers pay attention to two major areas, namely AM quality systems and the search for new regularities in already well-known materials that were produced in a traditional way. This technology has a number of advantages for the manufacture of aerospace products, but, like all production technologies, this technology has a number of disadvantages and problems. Residual internal stresses are one of the features of metal materials produced by layer-by-layer fusion using SLM technology, but they can significantly affect mechanical properties and geometric parameters. Their presence is especially important for AM materials, which inevitably lead to significant internal stresses. Thus, the issue of reducing the influence of internal stresses requires a fundamental understanding of their influence on the geometric parameters and service characteristics of AM materials.
