Intshayelelo:
Imimandla yokuvelisa okongeziweyo kunye neprototyping ekhawulezayo ibone utshintsho olubalulekileyo enkosi ngokuqhekeka komhlabaItekhnoloji yoshicilelo ye-3Dyaziwa njengei-stereolithography (SLA).U-Chuck Hull wenza i-SLA, uhlobo lokuqala loshicilelo lwe-3D, ngo-1980.Thina,FCE, iya kukubonisa zonke iinkcukacha malunga nenkqubo kunye nokusetyenziswa kwe-stereolithography kweli nqaku.
Imigaqo yeStereolithography:
Ngokusisiseko, i-stereolithography yinkqubo yokwakha izinto ezine-dimensional ukusuka kwimodeli yedijithali umaleko.Ngokuchasene neendlela eziqhelekileyo zokuvelisa (ezinjalo zokugaya okanye ukukrola), ezongeza into enye umaleko ngexesha, ukuprintwa kwe-3D-kuquka i-stereolithography-yongeza umaleko wezinto eziphathekayo.
Iikhonsepthi ezintathu eziphambili kwi-stereolithography zilawulwa ukupakishwa, ukunyanga i-resin, kunye ne-photopolymerization.
Ifotopolymerization:
Inkqubo yokufaka ukukhanya kwiresin elulwelo ukuyijika ibe yipolymer eyomeleleyo ibizwa ngokuba yifotopolymerization.
Ifotopolymerizable monomers kunye ne-oligomers zikhona kwiresin esetyenziswa kwi-stereolithography, kwaye zenza ipholima xa zivezwe kubude obuthile bokukhanya.
Ukunyangwa kweResin:
Ivat yeresin elulwelo isetyenziswa njengendawo yokuqala yoshicilelo lwe-3D.Iqonga elisezantsi kwevathi lintywiliselwa kwintlaka.
Ngokusekwe kwimodeli yedijithali, umqadi welaser we-UV ngokukhethayo uqinisa umaleko weresin engamaleko njengoko ujonga umphezulu wawo.
Inkqubo ye-polymerization iqalwa ngokubeka ngononophelo i-resin kwisibane se-UV, esiqinisa ulwelo lube yityabeka.
Ulwaleko oluLawulwayo:
Emva kokuba umaleko ngamnye uqina, iqonga lokwakha liyanyuswa ngokuthe ngcembe ukuze liveze kwaye linyange umaleko olandelayo weresin.
Umaleko ngokomaleko, le nkqubo iqhutywa de kuveliswe into epheleleyo ye-3D.
ULungiselelo lweModeli yeDijithali:
Ukusebenzisa isoftware yoyilo oluncediswa yikhompyuter (CAD), imodeli yedijithali ye-3D iyadalwa okanye ifunyenwe ukuqalisa inkqubo yoshicilelo lwe-3D.
Ukusika:
Umaleko ngamnye obhityileyo wemodeli yedijithali imele icandelo elinqamlezayo lezinto ezigqityiweyo.Umshicileli we-3D uyalelwe ukuba aprinte ezi zilayi.
Ushicilelo:
Umshicileli we-3D osebenzisa i-stereolithography ufumana imodeli esikiweyo.
Emva kokuntywilisela iqonga lokwakha kwintlaka yolwelo, i-resin iphiliswa ngokwendlela umaleko kusetyenziswa i-laser ye-UV ngokuhambelana nemiyalelo ecandiweyo.
Emva kokwenziwa komsebenzi:
Emva kokuba into ishicilelwe kwimilinganiselo emithathu, ithathwa ngokucophelela kwi-resin ye-liquid.
Ukucoca i-resin engaphezulu, ukuphilisa ngakumbi into, kwaye, kwiimeko ezithile, ukugalela okanye ukupolisha ukuze kugqitywe kakuhle yonke imizekelo yokulungiswa kwangemva.
Usetyenziso lweStereolithography:
I-Stereolithography ifumana izicelo kumashishini ahlukeneyo, kubandakanywa:
· Iprototyping: I-SLA isetyenziswa ngokubanzi kwiprototyping ekhawulezayo ngenxa yokukwazi ukuvelisa iimodeli ezineenkcukacha kakhulu nezichanekileyo.
· Uphuhliso lweMveliso: Isetyenziswa kuphuhliso lwemveliso ukwenza iiprototypes zokuqinisekiswa koyilo kunye novavanyo.
· Iimodeli zonyango: Kwicandelo lezonyango, i-stereolithography isetyenziselwa ukwenza imodeli entsonkothileyo ye-anatomical yokucwangcisa utyando kunye nokufundisa.
· Ukwenziwa koMveliso: Itekhnoloji isetyenziselwe ukuvelisa iinxalenye ezilungelelanisiweyo kunye namacandelo ahlukeneyo kumashishini.
Isiphelo:
Iitekhnoloji zale mihla zoshicilelo lwe-3D, ezibonelela ngokuchaneka, isantya, kunye nokuguquguquka kwimveliso yezinto ezintsonkothileyo ezine-dimensional ezintathu, zenziwe zanokwenzeka nge-stereolithography.I-Stereolithography iseyeyona nto iphambili kwimveliso eyongezelelweyo, inceda ukusungula uluhlu olubanzi lwamashishini njengoko iteknoloji ihambela phambili.
