Ububanzi bokusebenza be-UV curing 3DP bubanzi kakhulu, njengokwenza imodeli yegumbi eliyimodeli, imodeli yocingo oluphathwayo, imodeli yokudlala, imodeli yopopayi, imodeli yobucwebe, imodeli yemoto, imodeli yezicathulo, imodeli yosizo lokufundisa, njll. Ngokuvamile, yonke imidwebo ye-CAD ingenziwa kukhompyutha ingenziwa ibe yimodeli eqinile efanayo ngephrinta enezinhlangothi ezintathu.
Ukulungiswa okuphuthumayo okuphuthumayo komonakalo wempi yesakhiwo sendiza kuyindlela ebalulekile yokubuyisela ngokushesha ubuqotho bezindiza nokuqinisekisa inzuzo yobuningi bemishini.Ngaphansi kwezimo zempi, ukulimala kwesakhiwo sendiza kubalelwa ku-90% wawo wonke umonakalo.Ubuchwepheshe bokukhanda bendabuko abukwazi ukuhlangabezana nezidingo zokulungiswa komonakalo wezindiza zesimanje.Eminyakeni yamuva nje, ubuchwepheshe obusha obusanda kuthuthukiswa bezempi bezempi yethu obuseduze, obulula futhi obusheshayo bokulungisa ukulimala kwendiza bungahlangabezana nezidingo zokulungisa izinhlobo eziningi zezindiza nezinto ezihlukile.Idivayisi ephathekayo yokulungisa ngokushesha inganciphisa futhi isikhathi sokulungisa umonakalo wokulwa kwendiza, futhi ijwayelane nokukhanya okuvuthiwe okuphilisa ubuchwepheshe bokukhanda ngokushesha bomonakalo wokulwa kwendiza.
Ubuchwepheshe be-Ceramic UV obuphulukisa i-prototyping esheshayo wukwengeza impushana ye-ceramic kusixazululo se-UV ephulukisa i-resin, ukusabalalisa impushana ye-ceramic ngokulinganayo esixazululweni ngokushukumisa isivinini esikhulu, futhi ulungise i-ceramic slurry enokuqukethwe okuqinile okuphezulu kanye ne-viscosity ephansi.Ngemuva kwalokho, i-ceramic slurry ingungqimba olulashwe yi-UV ngokuqondile ngongqimba kumshini we-UV ophulukisa ngokushesha, futhi izingxenye ze-ceramic eziluhlaza zitholwa ngokubekwa okuphezulu.Okokugcina, izingxenye ze-ceramic zitholakala ngezinqubo zangemuva kokwelashwa ezinjengokomisa, ukwehlisa amafutha kanye nokucwiliswa.
Ubuchwepheshe be-prototyping bokukhanya obuphulukisayo bunikeza indlela entsha yamamodeli esitho somuntu angenziwa noma okunzima ukwenziwa ngezindlela zendabuko.Ubuchwepheshe be-prototyping bokwelapha ukukhanya obusekelwe ezithombeni ze-CT buyindlela ephumelelayo yokwenza izitho zokufakelwa, ukuhlela ukuhlinzwa okuyinkimbinkimbi, ukulungiswa komlomo kanye ne-maxillofacial.Njengamanje, ubunjiniyela bezicubu, isifundo esisha esihlanganisa imikhakha ehlukene esiphuma emkhakheni wocwaningo lwesayensi yezempilo, siwumkhakha othembisayo kakhulu wokusetshenziswa kobuchwepheshe bokwelapha be-UV.Ubuchwepheshe be-SLA bungasetshenziswa ukukhiqiza ama-scaffolds amathambo okufakelwa e-bioactive.Ama-scaffolds anezakhiwo ezinhle zemishini kanye ne-biocompatibility namaseli, futhi asiza ekunamatheleni nasekukhuleni kwama-osteoblasts.Ama-scaffolds wobunjiniyela bezicubu ezenziwe ubuchwepheshe be-SLA afakwe ama-osteoblasts egundane, futhi imiphumela yokufakelwa kwamaseli nokunamathela yayimihle kakhulu.Ngaphezu kwalokho, inhlanganisela yokukhanya okuphulukisa ubuchwepheshe be-prototyping esheshayo kanye nobuchwepheshe bokumisa iqhwa kungakhiqiza ama-scaffolds wobunjiniyela bezicubu zesibindi eziqukethe izinhlobonhlobo ze-microstructures eziyinkimbinkimbi.Uhlelo lwe-scaffolds lungaqinisekisa ukusatshalaliswa okuhlelekile kwezinhlobonhlobo zamaseli esibindi, futhi lunganikeza ireferensi yokulingisa i-microstructure ye-tissue engineering scaffolds yesibindi.
Ukuphrinta kwe-3D nokuphulukiswa kwe-UV - inhlaka yesikhathi esizayo
Ngesisekelo sokuzinza okungcono kokuphrinta, izinto ze-resin eziqinile ezilaphekayo ze-UV ziyathuthuka zibheke ngakuye isivinini esikhulu sokuphulukisa, ukuncipha okuphansi kanye ne-warpage ephansi, ukuze kuqinisekiswe ukunemba kwezingxenye, futhi zibe nezakhiwo ezingcono zemishini, ikakhulukazi umthelela kanye nokuguquguquka, ukuze zisetshenziswe ngokuqondile futhi zihlolwe.Ngaphezu kwalokho, kuzothuthukiswa izinto ezisebenzayo ezahlukahlukene, ezifana ne-conductive, kazibuthe, i-flame-retardant, ama-resin aqinile we-UV amelana nezinga lokushisa eliphezulu kanye nezinto eziqinile ze-UV ezinwebekayo.Izinto zokusekela zokupholisa i-UV kufanele futhi ziqhubeke nokuthuthukisa ukuzinza kwazo zokuphrinta.Umbhobho ungaphrinta noma nini ngaphandle kokuvikelwa.Ngesikhathi esifanayo, izinto zokusekela kulula ukususa, futhi izinto zokusekela ezincibilika emanzini zizoba ngokoqobo.
Ukuphrinta kwe-3D nokwelapha kwe-UV- μ- SL Technology
Ukukhanya okuphansi okuphulukisa i-prototyping esheshayo μ- SL (i-micro stereolithography) ubuchwepheshe obusha bokwenza i-prototyping obususelwe kubuchwepheshe bendabuko be-SLA, obuhlongozwe ngezidingo zokukhiqiza zezakhiwo zemishini emincane.Lobu buchwepheshe bubekwe phambili ekuqaleni kwawo-1980.Ngemva kweminyaka ecishe ibe ngu-20 yokucwaninga kanzima, iye yasetshenziswa ngezinga elithile.Okwamanje ehlongozwayo futhi yaqaliswa μ- SL ubuchwepheshe ikakhulukazi μ- SL ubuchwepheshe kanye-photon ezimbili ukumuncwa esekelwe μ- SL ubuchwepheshe kungaba ngcono ukwakha ukunemba bendabuko SLA ubuchwepheshe kuya submicron ezingeni, futhi uvule ukusetshenziswa ngokushesha prototyping ubuchwepheshe micromachining.Kodwa-ke, ingxenye enkulu ka-μ- Izindleko zobuchwepheshe bokukhiqiza i-SL ziphezulu kakhulu, ngakho-ke iningi labo lisesesigabeni saselabhorethri, futhi kusekhona ibanga elithile kusukela ekufezekeni kokukhiqizwa kwezimboni ezinkulu.
Amathrendi amakhulu wobuchwepheshe bokuphrinta be-3D esikhathini esizayo
Ngokuthuthuka okuqhubekayo nokuvuthwa kokukhiqiza okukhaliphile, ubuchwepheshe obusha bolwazi, ubuchwepheshe bokulawula, ubuchwepheshe bezinto ezibonakalayo nokunye sekusetshenziswe kakhulu emkhakheni wokukhiqiza, kanye nobuchwepheshe bokuphrinta be-3D nabo buzophushwa bufinyelele ezingeni eliphezulu.Ngokuzayo, ukuthuthukiswa kobuchwepheshe bokuphrinta be-3D kuzobonisa ukuthambekela okuyinhloko kokunemba, ubuhlakani, ukujwayelekile kanye nokulula.
Thuthukisa ijubane, ukusebenza kahle kanye nokunemba kokuphrinta kwe-3D, ukuthuthukisa izindlela zenqubo zokuphrinta okufanayo, ukuphrinta okuqhubekayo, ukuphrinta okukhulu nokuphrinta ngezinto eziningi, futhi uthuthukise ikhwalithi ephezulu, izakhiwo zemishini nezomzimba zemikhiqizo eqediwe, ukuze kuqashelwe. ukukhiqiza okuqondiswe ngqo kumkhiqizo.
Ukuthuthukiswa kwezinto ezihlukene zokuphrinta ze-3D, njengezinto ezihlakaniphile, izinto ezisebenzayo ze-gradient, izinto ze-nano, izinto ezihlukene kanye nezinto eziyinhlanganisela, ikakhulukazi ubuchwepheshe bokwenza insimbi eqondile, ubuchwepheshe bokwakha izinto zezokwelapha nezebhayoloji, kungase kube indawo eshisayo ocwaningweni lohlelo lokusebenza. kanye nokusetshenziswa kobuchwepheshe bokuphrinta be-3D esikhathini esizayo.
Ivolumu yephrinta ye-3D i-miniaturized kanye nedeskithophu, izindleko ziphansi, ukusebenza kulula, futhi kufanelekile kakhulu ngezidingo zokukhiqiza okusabalalisiwe, ukuhlanganiswa kokuklama nokukhiqiza, kanye nezicelo zansuku zonke zasendlini.
Ukuhlanganiswa kwesofthiwe kuqonda ukuhlanganiswa kwe-cad/capp/rp, kwenza ukuxhumana okungenazihibe phakathi kwesofthiwe yokuklama nesofthiwe yokulawula ukukhiqiza, futhi kuqaphela inkambiso eyinhloko yentuthuko yesikhathi esizayo yobuchwepheshe bokuphrinta be-3D ngaphansi kokulawulwa kwenethiwekhi okuqondile yabaklami - ukukhiqiza okukude ku-inthanethi.
Ukwenziwa kwezimboni kobuchwepheshe bokuphrinta be-3D kunendlela ende okufanele ihambe
Ngo-2011, imakethe yokuphrinta ye-3D yomhlaba wonke yayingama-US $ 1.71 billion, futhi impahla ekhiqizwe ubuchwepheshe bokuphrinta be-3D yabalelwa ku-0.02% wesamba somkhiqizo wokukhiqiza emhlabeni wonke ngo-2011. Ngo-2012, inyuke ngo-25% yafinyelela ku-US $ 2.14 billion, futhi kulindeleke ukuthi ukufinyelela ku-US $ 3.7 billion ngo-2015. Nakuba izimpawu ezihlukahlukene zibonisa ukuthi inkathi yokukhiqiza idijithali isondela kancane kancane, isekhona indlela yokunyathelisa ye-3D, eshisa futhi emakethe, ngaphambi kokuba izicelo zesikali sezimboni zindizele ezindlini. yabantu abajwayelekile.
