I-Selective Laser Sintering (SLS) ubuchwepheshe bokuphrinta be-3D obunamandla obuyingxenye yomndeni wezinqubo zokuhlanganisa i-powder bed, engakhiqiza izingxenye ezinembe kakhulu nezihlala isikhathi eside ezingasetshenziswa ngokuqondile ekusetshenzisweni kokuphela, ukukhiqizwa kwenqwaba encane noma ama-prototypes esandla.Phakathi nenqubo yokunyathelisa yomshini we-SLS, i-laser enamandla amakhulu isetshenziselwa ukuhlanganisa izinhlayiya ezincane zempushana yepulasitiki ibe yisimo esifiswayo sezinhlangothi ezintathu.I-laser ikhetha ngokukhetha okokusebenza okuyimpushana ngokuskena ingxenye yedatha enezinhlangothi ezintathu yendawo yombhede oyimpushana.Ngemva kokuskena isigaba ngasinye sesiphambano, umbhede wempuphu uncishiswa ungqimba olulodwa logqinsi, ungqimba olusha lwezinto ezibonakalayo lwengezwa phezu kwalo futhi inqubo yokukhetha i-laser sintering iphindaphindiwe kuze kube yilapho ingxenye isiqediwe.
Ukuphrinta kwe-SLS 3D kungasetshenziselwa kokubili izingxenye ze-polymer ezisebenzayo ze-prototyping kanye nokugijima okuncane kokukhiqiza, njengoba kunikeza izinga eliphezulu lenkululeko yokuklama, ukunemba okuphezulu futhi ikhiqiza izingxenye ezinezakhiwo ezinhle nezingaguquki zemishini.
Inqubo yokuphrinta ye-SLS
(Isithombe: Inqubo yokuphrinta ye-SLS)
Okokuqala, i-powder bin nendawo yokwakha iyashiswa eduze nezinga lokushisa elincibilikayo lezinto ezibonakalayo, futhi ungqimba lwe-powder material lubekwe.
Okwesibili, i-laser bese isetshenziselwa ukuskena ingxenye yesiphambano sesendlalelo, ukuze izinga lokushisa eliyimpushane likhuphuke lifike endaweni yokuncibilika, futhi ngokukhetha indawo edinga ukuphrinta, yakhe isibopho.
Okwesithathu, Ngemva kokuphothulwa kwe-sintering, iplatifomu yokwakha ihanjiswa phansi, futhi i-scraper ibekwe ngomunye ungqimba we-powder material, iphinda isinyathelo sesibili kuze kube yilapho yonke imodeli iphelile.
Okwesine, ngemva kokuqedwa kokunyathelisa, umgqomo wokwenza upholile (ngokuvamile ungaphansi kwama-degree angu-40), futhi izingxenye zingakhishwa futhi ukucubungula okulandelayo kungenziwa.
