Kukho iintlobo ezine eziphambili zeenkqubo zeUshicilelo lwe-3D, kwaye iinkqubo ezintsha zihlala zivela.Inkqubo nganye yokuvelisa ezongezelelweyo isebenzisa izinto ezahlukeneyo ukuvelisa amacandelo aneempawu ezizodwa ezisebenza kakuhle kwizicelo ezithile.
1. kukho i-photopolymerization
Ukunciphisa i-polymerization ye-photopolymers yolwelo enyangwa yi-photosensitive polymerization yenye yezona nkqubo zokuqala zokongezwa.Umaleko ochanekileyo we-Uv ngokunyanga umaleko kunye nokuqiniswa kweeleya ezicekethekileyo ze-photosensitive resins.Le ndlela, eyaziwa ngokuba yi-stereophotography, yathengiswa phakathi koo-1980.NgeyokuqalaUshicilelo lwe-3Ditekhnoloji engqondweni, iinxalenye zestereolithography zisetyenziselwa ukutyala imali kwizicelo ezinje ngeepateni zokuphosa, iiprototypes kunye neemodeli zeengqikelelo.Enye itekhnoloji ephawulekayo kukulungiswa kokukhanya kwedijithali.
2. ukukhutshwa kwezinto
Olu hlobo lokuvelisa olongezelelweyo lusasaza izinto ngokufudumeza umbhobho okanye ukukhupha intloko.Emva kokubeka umaleko omnye, yehla ukuze wakhe iqonga, okanye uhambise intloko ye-extrusion phezulu ukuze uprinte umaleko olandelayo phezu kwendawo yangaphambili.Izinto eziluhlaza ngokuqhelekileyo ziyi-thermoplastic filament, inxeba kwi-spool kwaye inyibilika xa ikhutshwe.Ubuchule obuqhelekileyo bokusebenzisa le ndlela kukutyhilwa okutyhidiweyo.Olu hlobo lokuvelisa okongeziweyo lunokusetyenziselwa iindawo zokuvelisa, izixhobo zokuvelisa, kunye neeprototypes ezisebenzayo ngenxa yokukwazi ukwakha ngezinto eziqhelekileyo ze-thermoplastic.
3. i-powder layer fusion
Umdibaniso womaleko wepowder ummandla wecandelo lomnqamlezo womgubo odityaniswe ngamandla obushushu.Ubushushu bunyibilikisa umgubo kwaye buqina xa buphola.Ngeepolymers, i powder engasetyenziswanga ejikeleze inxalenye isetyenziselwa ukubamba inxalenye endaweni, ngoko akukho nkxaso eyongezelelweyo idla ngokufuneka.Kwiingxenye zetsimbi, iihange zivame ukufunwa ukuba zidibanise iinxalenye kwibhedi yokushicilela kunye nokuxhasa ukucwangciswa kwezantsi.I-Laser sintering yathengiswa ngo-1992, ilandelwa yi-high-speed sintering kwaye, kutsha nje, i-multi-jet fusion.Kwimveliso yesinyithi, i-laser sintering yentsimbi ethe ngqo kunye ne-electron beam melting molding (EBM) ziinkqubo zemizi-mveliso ezaziwa kakhulu.
4. Ukutshiza ngezinto eziphathekayo
Inaliti yezinto yenye yezona ndlela zikhawulezayo zokwenza ezongezo zisebenzisa iintloko zoshicilelo lwemilomo emininzi.Idiphozithi yokwenziwa kwemveliso eyongezelelweyo amathontsi ezinto zokwakha umaleko ngokomaleko.Inkqubo yesitofu yeMaterial inokuprinta iinxalenye zemathiriyeli ezininzi kunye nemigangatho.Izixhobo ziveliswa ngokwemilinganiselo eyahlukeneyo yezinto nganye, okukhokelela kwimibala eyahlukeneyo kunye neentlobo zezinto eziphathekayo.Ngokuqhelekileyo, ezi nkqubo zisebenzisa i-photopolymers, i-wax kunye nezixhobo zedijithali apho i-photopolymers ezininzi zixutywe kwaye zitshizwe ngaxeshanye.Ubuchwephesha obufana nemodeli yeejethi ezininzi kunye nejethi zisetyenziselwa ukwenza iprototyping ekhawulezayo, imodeli yengqikelelo, iipatheni zokubeka utyalo-mali, kunye neemodeli zonyango ezingokoqobo ze-anatomical.
