description: The object of the study was gas flows propagating during direct energy deposition in a protective chamber. The main purpose of the bachelors work is the design of a protective chamber and the calculation of gas flows in the process of directed energy deposition. To achieve this goal, it was necessary to design a protective chamber, to develop a calculated model of gas flows to minimize the amount of oxygen in the chamber, so that the constructed product would not crack after printing. In the final qualifying work on the topic "Design of a protective chamber and calculation of gas flows in the process of directed energy deposition", a literary review of additive technologies and their types was made, the process of directed energy deposition was analyzed. A protective chamber has been designed in the process of directed energy deposition. A computational model of gas flows has been developed. The influence of swirlers, as well as a gas pipe at the base of the protective chamber for the retention and uniform distribution of argon inside the chamber is analyzed. As a result of the work, an open-type protective chamber was designed and calculations were performed to simulate gas flows in the process of directed energy deposition.
