I-Stereolithography (i-SLA okanye i-SL; ekwabizwa ngokuba yi-vat photopolymerization, i-optical fabrication, i-photo-solidification, okanyeushicilelo lwe-resin luhlobo lwetekhnoloji yoshicilelo ye-3D esetyenziselwa ukwenza imifuziselo, iiprototypes, iipateni, kunye namacandelo emveliso kumaleko ngokwefashoni usebenzisa iinkqubo zefotochemical apho ukukhanya kubangela ukuba ii-chemical monomers kunye ne-oligomers zidibanise kunye zenze iipolima.
Ezo polima emva koko zenza umzimba oqinileyo onamacala amathathu. Uphando kule ndawo lwenziwe ngexesha le-1970s, kodwa eli gama laqulunqwa nguChuck Hull ngo-1984 xa wayefaka isicelo selungelo elilodwa lomenzi kwinkqubo, eyanikezelwa ngo-1986.I-Stereolithography ingasetyenziselwa ukudala i-prototypes yeemveliso ekuphuhlisweni, iimodeli zonyango, kunye ne-hardware yekhompyutha, kunye nakwezinye izicelo ezininzi. i-stereolithography iyakhawuleza kwaye inokuvelisa phantse naluphi na uyilo.
Izinto ezingamanzi ezisetyenziselwaSLA yoshicileloziqhele ukubizwa ngokuba yi "resins" kwaye ziipolymers zethermoset. Iintlobo ezininzi zeereyini ziyafumaneka ngokurhweba kwaye kuyenzeka ukuba usebenzise iireyini zasekhaya ukuvavanya iingoma ezahlukeneyo ngokomzekelo.Izinto eziphathekayo Iipropathi ziyahluka ngokobumbeko bokwenziwa: "izinto eziphathekayo zinokuthamba okanye ziqine, zizaliswe kakhulu zizinto ezizezinye ezifana neglasi kunye ne-ceramic, okanye zifakwe iipropathi zoomatshini ezifana nobushushu obuphezulu bokuphambuka okanye ukuchasana nempembelelo". Kutshanje, ezinye iiphononongo ziye zavavanya ukuba nokwenzeka kwezinto eziluhlaza okanye ezinokuphinda zisetyenziswe ukuvelisa iireyini "ezizinzileyo". Ukwahlulahlula iiresin kwezi ndidi zilandelayo:
I-1- Ii-resin ezisemgangathweni, kwiprototyping ngokubanzi.
I-2- I-resin zobunjineli, kwiimpawu ezithile zomatshini kunye ne-thermal.
3- Iireyini zamazinyo kunye nezonyango, kwiziqinisekiso ze-biocompatibility.
4- Iireyini ezinokugalelwa, zero zero isiqulatho sothuthu emva kokudinwa.
I-5- I-biomaterial resins, eziqulunqwe njengezisombululo zamanzi ze-polymers zokwenziwa ezifana ne-polyethylene glycol, okanye i-biological polymers ezifana ne-gelatin, i-dextran, okanye i-hyaluronic acid.
SLA 3d yoshicilelo yeyokuqala kwiinkqubo zokuvelisa ezongezelelweyo ezihlangeneyo ezaziwa ngokuba yi “3D printing”, ebiyeyona nkqubo ivuthiweyo nesetyenziswa ngokubanzi. idlala indima ebalulekileyo kuyilo lokuyila, unyango lwamazinyo, ukwenziwa kwemizi-mveliso, oopopayi bezandla, imfundo yasekholejini, imifuziselo yezakhiwo, imibumbo yobucwebe, ukwenza ngokwezifiso kunye nezinye iinkalo.
Ukuba ufuna ukwazi ulwazi oluninzi kwaye ufuna ukwenza imodeli yoshicilelo ye-3d, nceda uqhagamshelaneJSADD 3D Manufacturerngalo lonke ixesha.
