The thesis contains an overview of additive manufacturing technology and focuses more on the additive production of metal products. The procedure is described, where we printed metal test tubes of various shapes for tensile testing from stainless steel 17-4 PH using the additive manufacturing process on a 3D printer (Markforged Metal X). Additive manufacturing was followed by cleaning and sintering the samples for 26 hours in an argon atmosphere. The samples were first visually inspected, macro and micro abrasions were analyzed, hardness and tensile tests were measured. We found that the filling of the sample volume with material affects its shape, where the plan of the path of the additive head can cause insufficient filling of the volume. The mechanical properties are mainly affected by the shape and size of the sample products, and the negative impact is mainly shown by the filling of the volume with material. The shape of the test tubes does not affect the hardness of the test pieces.
