Abstract: The results of studies of dynamic properties of RS-553 powdered aluminum alloy samples obtained by additive technology (3D printing) by selective laser fusion are presented. The studies were performed using the traditional Kolsky method on a split Hopkinson rod at strain rates of $\sim$ 10$^3$ s$^{-1}$.

Keywords: Hopkinson split rod, RS-553 aluminum alloy, mechanical properties, additive technologies.
