Resumo

Metal products manufactured by means of additive technologies are usually characterized by unfavorable mechanical properties. Laser shock processing is mechanical processing of surfaces at a high strain rate, which hardens the near-surface layer and creates favorable mechanical properties. This work discusses the development of hybrid additive technology in combination with laser shock processing with additive technologies, and the role of laser shock processing in hybrid additive technology is analyzed using the finite element method. The results obtained demonstrate that the frequency of the hardened layer is a critical technological parameter influencing the redistribution of residual stresses, which strongly depends on the amount of heat released during 3D printing. Due to the results obtained, the hybrid additive technology developed occupies a position in various additive technologies and is promising for practical implementation as a new method for manufacturing high-quality metal products.
