Selective Laser Sintering (SLS) ndiukadaulo wamphamvu wosindikiza wa 3D womwe ndi wa banja la njira zophatikizira bedi la ufa, zomwe zimatha kupanga magawo olondola komanso olimba omwe angagwiritsidwe ntchito mwachindunji pomaliza, kupanga batch yaying'ono kapena ma prototypes amanja.Pa makina osindikizira a SLS, laser yamphamvu kwambiri imagwiritsidwa ntchito kuphatikizira tinthu tating'ono ta ufa wapulasitiki mu mawonekedwe omwe amafunidwa amitundu itatu.Laser mosankha amasakaniza zinthu za ufa posanthula gawo la data la magawo atatu a bedi la ufa.Pambuyo posanthula gawo lililonse la mtanda, bedi la ufa limachepetsedwa ndi wosanjikiza umodzi wa makulidwe, chinthu chatsopano chimawonjezeredwa pamwamba pake ndipo njira yosankha ya laser sintering imabwerezedwa mpaka gawolo litatha.
Kusindikiza kwa SLS 3D kungagwiritsidwe ntchito pazigawo zonse za prototyping zogwira ntchito za polima komanso zoyendetsa zazing'ono, chifukwa zimapereka ufulu wodziyimira pawokha, wolondola kwambiri ndikupanga magawo okhala ndi makina abwino komanso osasinthasintha.
Njira yosindikizira ya SLS
(Chithunzi: SLS Printing Process)
Choyamba, nkhokwe ya ufa ndi malo omangira amatenthedwa pafupi ndi kutentha kwa zinthuzo, ndipo gawo la ufa limayikidwa.
Chachiwiri, laser imagwiritsidwa ntchito poyang'ana gawo la mtanda, kotero kuti kutentha kwa ufa kumakwera mpaka kusungunuka, ndikusankha malo omwe amafunika kusindikizidwa, kupanga chomangira.
Chachitatu, Akamaliza sintering, nsanja yomanga imasunthidwa pansi, ndipo scraper imayikidwa ndi wosanjikiza wina wa zinthu za ufa, kubwereza sitepe yachiwiri mpaka chitsanzo chonse chatsirizidwa.
Chachinayi, kusindikiza kumalizidwa, bin yopangirayo yakhazikika (nthawi zambiri imakhala pansi pa madigiri 40), ndipo zigawozo zimatha kutulutsidwa ndikukonzanso kotsatira.
Iyi ndi njira yathu yosindikizira ya SLS.Kuti mumve zambiri, chonde pitani patsamba lathu www.jsaddive.com
