Abstract

U ovom radu opisani su utjecaji parametara izrade selektivnog laserskog taljenja (SLM) na svojstva Co-Cr legura koje se koriste za dentalnu primjenu. Rad se sastoji od pet poglavlja od kojih su četiri poglavlja posvećena teoretskom dijelu rada, a jedno poglavlje je posvećeno eksperimentalnom dijelu rada. Prvo poglavlje je uvod u tematiku, drugo poglavlje obrađuje aditivnu proizvodnju općenito, obrađuje se klasifikacija aditivne proizvodnje, aditivna proizvodnja metala, procesi aditivne proizvodnje s i bez lasera. Osim toga u drugom poglavlju je detaljno obrađen postupak selektivnog laserskog taljenja. Treće poglavlje odnosi se na aditivnu proizvodnju u dentalnoj primjeni gdje se obrađuju zahtjevi na materijale u dentalnoj primjeni i Co-Cr legure za dentalnu primjenu. Četvrto poglavlje pokriva eksperimentalni dio ovog rada u kojem su detaljno obrađeni strojevi na kojima su se izrađivali ispitni uzorci, norma, a opisani su i postupci statičko vlačnog ispitivanja, karakterizacije mikrostrukture i ispitivanja mikrotvrdoće. U konačnici u petom poglavlju doneseni su zaključci o tome na koji način parametri izrade utječu na svojstva 3D printanih Co-Cr legura.

Abstract (english)

This paper describes effects of 3D print manufacturing parameters on properties of cobalt-chromium (Co-Cr) alloys in dental medicine. Paper consists of five chapters of which four are theory based and one is describing the experiment. First chapter is introduction to paper, second chapter offers detailed view of additive manufacturing in general, classification of additive manufacturing processes, additive manufacturing of metals and additive manufacturing of metals with and without lasers. Also, in second chapter there is detailed overview of selective laser melting process. Third chapter consists of overview of additive manufacturing in dental medicine with classification of requirements on metal materials which are used in dental medicine. Also, in third chapter you can find everything about cobalt-chromium alloys for dental medicine. Fourth chapter covers experiment and detail explanation of procedures used. Final, in the fifth chapter, there is conclusion about how manufacturing parameters affect properties of cobalt-chromium alloys in dental medicine.
