20.500.12556/RUL-175769 Dovajalnik prahu za proces selektivnega laserskega taljenja z manjšimi količinami prahu Powder feeder for selective laser melting process with smaller quantities of powder Proces selektivnega laserskega taljenja (SLT) kovinskega prahu je eden od najpogosteje uporabljenih procesov za izdelavo kompleksnih komponent z dodajalno tehnologijo. Industrijske izvedbe sistemov običajno ne omogočajo izvedbe SLT procesa z manjšimi količinami prahu, kar omejuje njihovo uporabo pri razvoju in tiskanju z novimi prašnimi materiali. V ta namen smo zasnovali sestav zalogovnika prahu z nanašalom in dodatni sestav prekrivne plošče in sekundarne ploščadi za sistem DMG MORI Lasertec 30 SLM, s čimer smo proces SLT omejili na manjšo delovno površino in zmanjšali zahtevano količino prahu. Zalogovnik z nanašalom smo oblikovali na osnovi poskusov. Z izvedbo procesa SLT smo tudi potrdili zmožnost njegove uporabe za izdelavo komponent z manjšo količino prahu. The selective laser melting (SLM) process of metal powder is among the most widely used processes for fabricating complex components using additive manufacturing. Industrial systems typically do not allow the SLM process to be done with reduced quantities of powder, which limits their use in research and utilisation of new powder materials. We have therefore developed a powder hopper system with a recoater with an additional cover plate and secondary platform assembly for the DMG MORI Lasertec 30 SLM system, which limits the SLM process to a smaller work surface and lowers the amount of powder required. The design of the powder feeder was based on experiments. By performing the SLM process, we also confirmed its ability of producing components with a smaller quantity of powder. dodajalne tehnologije selektivno lasersko taljenje zalogovnik za prah postelja prahu konstruiranje additive manufacturing selective laser melting powder hopper powder bed mechanical design true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-11-07 08:30:29 2025-11-07 08:30:35 2025-12-15 03:46:03 0000-00-00 00:00:00 2025 0 0 XII, 38 f., [22] f. pril. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.925.84:628.511.133(043.2) 278873 256690947 45506.pdf 45506.pdf 1 DCF6F65B168BFCE5A17CA88C3D854D55 d060aa3bb35c409e4879fd1f06cf3c5d2ab25ec1a21fb53ffa1dc0b75fe68119 572f91d4-bbab-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=221616 45507.pdf 45507.pdf 1 A21117C53AD152960868A525F6BFCF1F ac2e48a059013c21edf15956f72b9d938c9e01d71a89d6512a8c5ebcdb47d0e8 5731ff54-bbab-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=221617 Fakulteta za strojništvo 0 0 0
