Nekuvandudzwa kwesainzi uye tekinoroji uye nekusimudzirwa kwekushandiswa kwekudiwa, kushandiswa kwekukurumidza prototyping kugadzira zvakananga simbi inoshanda zvikamu zvave nzira huru yekusimudzira yekukurumidza prototyping.Parizvino, simbi huru3D kudhinda maitiro anogona kushandiswa kugadzira zvakananga simbi inoshanda zvikamu zvinosanganisira: Selective Laser Sintering(SLS) teknolojia, Yakananga Metal Laser Sintering(DMLS)tekinoroji, Selective Laser Melting (SLM)teknolojia, Laser Engineered Net Shaping(LENS)tekinoroji uye Electron Beam Selective Melting(EBSM)tekinoroji, nezvimwewo.
Sarudza laser sintering(SLS)
Kusarudza laser sintering, sezvinoreva zita, inotora mvura chikamu sintering metallurgical mechanism.Munguva yekugadzira, iyo hupfu inonyungudutswa zvishoma, uye zvimedu zvehupfu zvinochengeta zvakaomesesa chikamu macores, ayo anozorongedzerwa patsva kuburikidza neanotevera akasimba chikamu masisitimu uye fluid chikamu kusimba.Bonding inowana hupfu densification.
SLS tekinorojimusimboti uye maitiro:
Iyo yese process mudziyo inoumbwa nehupfu humburumbira uye silinda yekugadzira.Iyo hupfu humburumbira piston (powder feeding piston) inosimuka, uye iyo poda yakaisa roller inoparadzira hupfu pahumburu yepiston yekugadzira (iri kushanda piston).Iyo komputa inodzora maviri-dimensional scanning trajectory yelaser beam zvinoenderana nechidimbu modhi yeiyo prototype, uye inosarudza sinter iyo yakasimba poda zvinhu kuti iite musara wechikamu.Mushure mekupedzwa kwechitubu, piston inoshanda inodzikiswa imwe yakakora, iyo poda yekuisa sisitimu inoiswa nehupfu hutsva, uye laser beam inodzorwa kuti itarise uye kunyudza iyo itsva layer.Kutenderera uku kunoramba kuchienderera mberi, layer by layer, kusvika zvikamu zvitatu-dimensional zvaumbwa.
