Abstract: In recent times, 3D printing technologies are a young and actively developing production sector for many areas of economy, from aerospace and mechanical engineering to medicine. The obvious advantage of introduction of the additive technologies in medicine and in particular in dentistry is high accuracy in producing complex details, individually designed implants and prostheses for their maximum match with a place of injury or a substituted object, considerable reduction both the product materials and auxiliary materials usage. However, questions arise about the limits of applicability and reliability of the additive technologies with their active introduction. The properties of dental crowns made of nickel-chromium alloy NH-Dent NS vac and cobalt-chromium powder PR-KH28M6 were studied in this research. For the production of samples was used selective laser melting technology, which belongs to a number of additive technologies, and the casting technology in the mold. A comparative analysis of the microstructure of the samples, the surface profile and the Vickers hardness was carried out.

Keywords: additive technologies, medicine, dentistry, selective laser melting technology, selective laser melting, microstructure, surface profile, hardness of samples
