I-Stereolithography (SLA) – Ukhetho Olufanelekileyo Lokuprinta Nge-3D Echanekileyo Kakhulu
I-Stereolithography (i-SLA okanye i-SL) yiteknoloji yokuprinta ye-3D echanekileyo kakhulu esebenzisa i-resin ethambileyo njengezinto eziluhlaza. Le teknoloji isebenzisa iipropati zokunyanga ngokukhawuleza ze-resin ethambileyo phantsi kokukhanya kwe-UV laser ethile, okuvumela ukwenziwa kwezakhiwo ze-3D ezintsonkothileyo ngokusebenzisa ukwenziwa komaleko ngomaleko.
Ngexesha lenkqubo yokwenziwa, i-resin ethambileyo yolwelo idlula kwi-polymerization kunye ne-solidization ngoko nangoko xa ivezwe kukukhanya kwe-UV (ububanzi be-wavelength malunga ne-250-400nm). Umatshini we-SLA ugxila ngokuchanekileyo i-UV laser kumphezulu we-resin ethambileyo yokukhanya, kancinci kancinci i-resin ukusuka kwindawo ukuya kumgca uze emva koko ukusuka kumgca ukuya kumphezulu, ifezekisa imifanekiso echanekileyo yomgca ngamnye. Umaleko ngomaleko, kwakhiwa imodeli ye-3D eqinileyo neneenkcukacha.
I-Stereolithography inika iingenelo ezinje ngokuchaneka okuphezulu kokubumba, iindawo ezigudileyo, kunye nokuveliswa kweenkcukacha ezinesisombululo esiphezulu. Isetyenziswa kakhulu ekwenzeni iimodeli zoshishino, kuyilo lwezixhobo zonyango, kuyilo lobucwebe, ekuveliseni ukubumba, nakwi-prototyping ephezulu. Ukwenziwa kwayo ngokukhawuleza nangokuchanekileyo kunciphisa kakhulu imijikelo yophuhliso lwemveliso, kuzisa ukuguquguquka okukhulu kunye nokuvelisa izinto ezintsha kwishishini lokuvelisa.
I-SLA (i-Stereolithography) ayisiyo kuphela iteknoloji ebalulekileyo ekuprinteni nge-3D, kodwa ikwasisisombululo esisebenzayo kakhulu sokufezekisa i-prototyping esemgangathweni ophezulu kunye nemveliso eyenziwe ngokwezifiso ngamanani amancinci, inceda iinkampani ukuba zifezekise imigangatho ephezulu ekuveliseni ngokuchanekileyo.
IiResins zeRadical Photosensitive zasimahla:
Iingenelo: Ixabiso eliphantsi, ukunyanga ngokukhawuleza, ukuqina okuhle, ukuxinana okuphantsi
Iingxaki: Ukuthintela ioksijini okuphawulekayo, ukuncitshiswa okukhulu, ukugoba kweemveliso eziprintiweyo, ukuchaneka okuphantsi, kunye nesidingo sokulungiswa kwesibini
IiResins zeCationic Photosensitive:
Iingenelo: Ukuncipha komthamo xa uvuselelwa, izinga eliphezulu lokuphendula, akukho mfuneko yokulungiswa kwesibini emva kokubumba, ayichaphazeleki kukuthintela ioksijini, uzinzo oluhle lobukhulu, iipropati ezintle zoomatshini, kunye nokuchaneka okuphezulu.
Iingxaki: Isantya sokuphendula esicothayo, i-viscosity ephezulu, ii-vinyl ethers zinedosi ephezulu yokuvezwa kwaye ziyaphiliswa kancinci; ii-epoxies ziyaqhekeka
Iinkqubo zeHybrid:
Iinkqubo ze-acrylate-epoxy hybrid zidibanisa le migaqo mibini yokuphilisa ekhankanyiweyo apha ngasentla, kunye nabaqalisi be-cationic kunye ne-free radicals abasebenza kunye.
Iiresini zokuprinta ze-3D zahlulwe zibe ziiresini ezi-free radical photosensitive resins, iiresini ezi-cationic photosensitive resins, kunye neenkqubo ze-hybrid. U-Ever Ray, umenzi onamava eminyaka engama-20 ogxile kwimveliso nophuhliso lweeresini ezinokunyangwa, uqhayisa ngomthamo wonyaka wemveliso yeetoni ezingama-20,000, umgca wemveliso opheleleyo, kunye nokukwazi ukwenza ngokwezifiso iimveliso. Iiresini zokuprinta ze-3D ziquka iPolyurethane 7224-1, 7200, 7296-1, kunye ne-7253A-5.
