The Kosice Summit of Innovation and Technology (KSIT 2024) was held in Železiarne Podbrezová a.s. facilities from November 2-5, 2024, at the Hotel Stupka. The conference was organised to mark the 30th anniversary of founding the scientific journal Acta Metallurgica Slovaca. KSIT 2024 also covers some interesting topics. More lectures are presented on issues related to additive manufacturing (AM). Given the expanding and invaluable role of simulation tools, which can currently be applied to various production processes, an interesting lecture was given at the KSIT conference regarding using the simulation tool Simufact Additive. Current knowledge was also presented in the field of joining materials focused on hybrid methods of joining materials, especially sheets used in producing car bodies. Currently, the concepts of materials used for car bodies differ significantly, with the goal being to reduce the body's weight, thereby reducing fuel consumption and, on the other hand, increasing the passive safety of the crew. Individual car manufacturers' body construction concepts use different materials, such as ferrous and non-ferrous metals.
