This work contributes to the problem of individual replacements of worn human joints by applying new types of implants and materials, made using modern additive technologies (melting of metal powders by laser and electron beam). The main attention is paid to the method called Electron Beam Melting used with the ARCAM Q10plus machine. Analyses of the sintered Ti6Al4V - ELI alloy samples were made from the point of view of production precision and quality (electron microscopy Tescan MIRA 3GM, Alicona IF G5, Mahrvision MM 420) after sintering in different technological modes and the surface quality reached after turning and tumbling (OTEC, machine DF5], including measurement and calculations of other physical quantities. The results confirm an important effect of sample inclination in the chamber when building on the precision of the shape and quality of the surface. Furthermore, the material exhibits high resistance to machining, expressed in terms of force loading and specific cutting forces (KISTLER dynamometer 9575B, Dynoware), measured for a range of feed per rotation 0.05-0.40mm, cutting speed 48 m/min, depth of cut 1.0 mm and use of coated cemented carbides (CNMG 120404ER-SI 8030/ PCLNR 2020 K 12, in dry cutting conditions. Nevertheless, a high quality after machining can be reached. The quality can be improved more by two-steps tumbling technology so finally a glossy surfaces (Ra< 0.036 m) with high material ratio (Abbot-Firestone curves) were found.
