SLM, iro zita rakazara re selectivelasermelting, inonyanya kushandiswa mu molds, dentures, medical, aerospace, etc.
Metal 3D kudhinda yakashongedzerwa ne500W fiber laser, ine collimation system uye yakakwirira-chaiyo scanning galvanometer, yakanaka nzvimbo uye optical mhando inogona kuwanikwa, saka SLM simbi 3D kudhinda kune yakakwirira kuumba kurongeka.
SLM tekinorojindiyo tekinoroji umo simbi yakachena poda yakanyungudutswa pasi pekupisa kwelaser beam uye inoumbwa nekutonhodza uye kusimba.SLM tekinoroji inowanzoda kuwedzera zvimiro zvekutsigira.Mabasa ayo makuru ndeaya: kutanga, kuita inotevera unmolded poda layer, kudzivirira iyo laser scanning kune yakanyanyisa gobvu simbi poda layer uye kudonha.Chechipiri, mushure mokunge hupfu hunopisa, hukanyunguduka uye hunotonhora panguva yekuumbwa kwekugadzira, kune shrinkage stress mukati, zvichiita kuti zvikamu zviputike, nezvimwewo. inogona kudzora kushushikana kwekunetseka kwezvikamu zvakaumbwa, uye kusimba kwechigadzirwa kwakakwira kupfuura kweSLS.
Mukuita kwesimbi 3D kudhinda, kuitira kudzivirira oxidation yesimbi poda nemhepo, inofanirwa kuitwa mune inert gasi (isina okisijeni) nharaunda.
Zvinhu zvikuru zveSLM 3D kudhindaari titanium alloy, simbi isina tsvina, aluminium alloy, cobalt-chromium alloy, die simbi, nezvimwe.
