3D PRINTING : DIRECT METAL LASER SINTERING

U ovom radu prikazan je pregled razvoja 3D printanja, posebno metode DMLS-a. Dan je povijesni pregled razvoja 3D printanja kroz prve korake komercijalizacije proizvodnje, pojave DMLS-a i daljnjeg razvoja tog procesa kroz godine. Prikazan je pregled razvoja uređaja, laserskih izvora za obradu materijala, koji je u ovom procesu korišten u obliku praha. Prikazano je kako se s novim saznanjima razvijao procesi korišteni materijali te kako je došlo do usavršavanja proizvodnje i performansi. Objašnjeno je zašto je kvalitetan kompjuterski dizajn predmeta ključan faktor prije započinjanja izrade krajnjeg proizvoda. Kako oblik dizajna utječe na sprječavanje lomova, poboljšanja svojstava predmeta te na kvalitetu proizvoda. Prikazane suvarijable koje je potrebno uzeti u obzir tijekom procesa DMLS-a. Na kraju je prikazano kako će daljnje razvijanje 3D printanja imati snažan pozitivni globalni utjecaj na proizvodnju i ukupnu ekonomiju.This paper present an overview of development 3D printing, special the methods of DMLS. A review of historical development of 3D printing has been presented through the first steps of comercialization of production, invention of DMLS and the further development this process trought the years. An overview of development device, laser sources for processing materials, which is in this process used in powder form. It has shown how the process and materials have been developed with new knowledge and how production and performance progress has been achieved. It explain, why thehigh quality of computer designis a preliminary key factor before the start of product final production. How the form of design influences on the prevention of product fractures, improve product properties, and the product quality. The variables which should be taken into consideration during the process of DMLS are shown. Finally, it is shown that a further development of 3D printing will have a strong, positive global impact on the production and overall economy
