Tested samples were made of pure iron on machine SLM280HL based on Selective Laser Melting method (SLM). The pure iron was selected as a semi-finished product for future manufacturing of a magnetic circuit in magnetorheological damper. The magnetic circuit is an inseparable part of damper piston, which is high mechanically loaded during the operation. Therefore, it is highly important to have suitable mechanical properties. The free-cutting steel 11SMn30 was used as a reference sample. Five different settings of laser power, scanning speed and hatch distance were used for preparation of five sets of samples. The highest tensile strength was achieved at samples produced with the highest energy density and the lowest volume speed of building. These conditions were achieved by laser power 300 W, scanning speed 750 mm/s and hatch distance 84 m. The tensile strength of these samples was 461 MPa, which is higher than at reference steel (452 MPa). From the point of view of economic aspects, the second most strength steel is better choice, because its tensile strength is 456 MPa but the building speed is about 50 % higher.
