Ushicilelo lwe-3D kunye nokunyanga kwe-UV-Izicelo

Umda wesicelo se-UV yokunyanga i-3DP ubanzi kakhulu, njengokwenza imodeli yegumbi lemodeli, imodeli yefowuni ephathwayo, imodeli yokudlala, imodeli yopopayi, imodeli yobucwebe, imodeli yemoto, imodeli yezihlangu, imodeli yoncedo lokufundisa, njl. Ngokuqhelekileyo, yonke imizobo yeCAD ingenziwa kwikhompyuter inokwenziwa ibe yimodeli eqinileyo efanayo ngomshicileli one-dimensional-ntathu.

Ukulungiswa ngokukhawuleza okukhawulezileyo komonakalo wedabi lwenqwelomoya yindlela ebalulekileyo yokubuyisela ngokukhawuleza ingqibelelo yenqwelomoya kunye nokuqinisekisa ubuninzi benzuzo yezixhobo.Ngaphantsi kweemeko zemfazwe, umonakalo owenziwe kwinqwelomoya uthatha malunga ne-90% yazo zonke iziganeko zomonakalo.Itekhnoloji yokulungisa yemveli ayinakuhlangabezana neemfuno zokulungiswa komonakalo wenqwelomoya yanamhlanje.Kwiminyaka yakutshanje, itekhnoloji esanda kuphuhliswa yomkhosi wenqwelomoya edabini, efanelekileyo kunye nekhawulezayo yokulungisa imeko kaxakeka inokuhlangabezana neemfuno zokulungisa iintlobo ezininzi zeenqwelomoya kunye nezixhobo ezahlukeneyo.Isixhobo esiphathwayo sokulungiswa komonakalo okhawulezileyo singalenza libe lifutshane ngakumbi ixesha lokulwa nomonakalo kwinqwelomoya, kwaye liziqhelanise nokukhanya okuthe kratya okunyanga itekhnoloji yokulungisa ngokukhawuleza umonakalo wokulwa wenqwelomoya.

I-Ceramic UV ephilisa itekhnoloji ye-prototyping ekhawulezayo kukongeza umgubo we-ceramic kwisisombululo se-UV yokunyanga intlaka, ukusasaza umgubo we-ceramic ngokulinganayo kwisisombululo ngokushukumisa isantya esiphezulu, kwaye ulungiselele uludaka lwe-ceramic olunomxholo oqinileyo kunye ne-viscosity ephantsi.Ke, i-ceramic slurry i-UV ephiliswe ngokuthe ngqo ngumaleko kumatshini wokuphilisa we-UV okhawulezayo, kwaye iindawo eziluhlaza ze-ceramic zifunyanwa ngokugqwesa.Ekugqibeleni, iinxalenye ze-ceramic zifumaneka ngeenkqubo zokunyanga emva kokunyanga ezifana nokumisa, ukuchithwa kunye nokutshisa.

Ukukhanya okuphilisa iteknoloji yeprototyping ngokukhawuleza inika indlela entsha yeemodeli zamalungu omntu ezingenakwenziwa okanye kunzima ukuba zenziwe ngeendlela zendabuko.Ukukhanya okuphilisa iteknoloji yeprototyping esekelwe kwimifanekiso ye-CT yindlela esebenzayo yokwenza i-prosthesis, isicwangciso sotyando olunzima, ukulungiswa komlomo kunye ne-maxillofacial.Okwangoku, ubunjineli beethishu, isifundo esitsha samacandelo ohlukeneyo esiphuma kumda wophando lwenzululwazi yobomi, licandelo elithembisayo letekhnoloji yokunyanga i-UV.Itekhnoloji ye-SLA ingasetyenziselwa ukuvelisa i-bioactive scaffolds bone bone.I-scaffolds ineempawu ezilungileyo zomatshini kunye ne-biocompatibility kunye neeseli, kwaye zilungele ukunamathela kunye nokukhula kwe-osteoblasts.I-scaffolds yobunjineli be-tissue eyenziwe yi-teknoloji ye-SLA yafakelwa i-osteoblasts ye-mouse, kunye nemiphumo yokufakelwa kweeseli kunye nokubambelela kwakukuhle kakhulu.Ukongeza, ukudityaniswa kokukhanya okuphilisa itekhnoloji yeprototyping ekhawulezayo kunye netekhnoloji yokumisa umkhenkce inokuvelisa i-scaffolds yobunjineli besibindi equlethe iindidi ezahlukeneyo ze-microstructures.Inkqubo ye-scaffolds inokuqinisekisa ukuhanjiswa okucwangcisiweyo kweentlobo ezahlukeneyo zeeseli zesibindi, kwaye inokubonelela ngereferensi yokulinganisa i-microstructure ye-tissue engineering scaffolds.

Ushicilelo lwe-3D kunye nokunyanga kwe-UV-i-resin yexesha elizayo

Ngokwesiseko sozinzo olungcono loshicilelo, izixhobo ze-resin ezinyangekayo ze-UV ziphuhla zisiya kwicala lesantya esiphezulu sokunyanga, ukushwabana okuphantsi kunye ne-warpage ephantsi, ukuze kuqinisekiswe ukuchaneka kwamalungu, kunye neempawu ezingcono zoomatshini, ngakumbi impembelelo kunye nokuguquguquka, ukuze zisetyenziswe ngokuthe ngqo kwaye zivavanywe.Ukongeza, izixhobo ezahlukeneyo zokusebenza ziya kuphuhliswa, ezinje nge-conductive, imagnethi, i-flame-retardant, i-UV ekwazi ukumelana nobushushu obuphezulu kunye ne-UV elastic resin materials.Izinto ezixhasayo zokunyanga i-UV kufuneka ziqhubeke nokuphucula uzinzo lwayo lokushicilela.Umbhobho unokuprinta nangaliphi na ixesha ngaphandle kokukhusela.Ngelo xesha, izinto ezixhasayo zilula ukususa, kwaye ukuxhaswa kwenkxaso yamanzi ngokupheleleyo kuya kuba yinyani.

3D yoshicilelo kunye UV ukunyanga- μ- SL Technology

Ukukhanya okuphantsi okunyanga iprototyping ekhawulezayo μ- SL (i-stereolithography encinci) yitekhnoloji entsha ekhawulezayo yokuchwetheza esekelwe kubugcisa bemveli be-SLA, ecetywayo kwiimfuno zokwenziwa kwezakhiwo zoomatshini ezincinci.Le teknoloji ibekwe phambili kwasekuqaleni kwe-1980s.Emva kweminyaka ephantse ibe ngama-20 yophando olunzima, luye lwasetyenziswa ukusa kumlinganiselo othile.Ngoku ecetywayo kwaye iphunyezwe μ- SL iteknoloji ingakumbi ibandakanya μ- SL ubuchwepheshe kunye-photon-ezimbini ukufunxa esekelwe μ- SL iteknoloji inokuphucula ukubunjwa ukuchaneka yemveli SLA iteknoloji kwinqanaba submicron, kwaye uvule isicelo sobugcisa prototyping ngokukhawuleza micromachining.Nangona kunjalo, uninzi lwe-μ- Iindleko zeteknoloji yokuvelisa i-SL ziphezulu kakhulu, ngoko ke uninzi lwazo lusekwinqanaba lebhubhoratri, kwaye kusekho umgama othile ukusuka ekuphunyezweni kwemveliso yemizi-mveliso emikhulu.

Iindlela eziphambili zetekhnoloji yoshicilelo lwe-3D kwixesha elizayo

Ngophuhliso olongezelelweyo kunye nokuvuthwa kokuveliswa okukrelekrele, itekhnoloji yolwazi olutsha, itekhnoloji yolawulo, itekhnoloji yezinto eziphathekayo njalo njalo zisetyenziswe ngokubanzi kwintsimi yokuvelisa, kunye nobugcisa bokushicilela be-3D buya kutyhalelwa kwinqanaba eliphezulu.Kwixesha elizayo, uphuhliso lwetekhnoloji yoshicilelo lwe-3D luya kubonisa iindlela eziphambili zokuchaneka, ubukrelekrele, ukwenziwa ngokubanzi kunye nokulula.

Ukuphucula isantya, ukusebenza kakuhle kunye nokuchaneka koshicilelo lwe-3D, ukuphuhlisa iindlela zenkqubo yoshicilelo oluhambelanayo, ushicilelo oluqhubekayo, ushicilelo olukhulu kunye noshicilelo lwezinto ezininzi, kunye nokuphucula umgangatho womphezulu, iipropathi zoomatshini kunye nezomzimba zeemveliso ezigqityiweyo, ukuze kuqondwe. imveliso ejolise ngqo kwimveliso.

Ukuphuhliswa kwezixhobo zokushicilela ze-3D ezahlukeneyo, ezifana nezixhobo ezihlakaniphile, izinto ezisebenzayo zegradient, izinto ze-nano, izinto ezingafaniyo kunye nezixhobo ezidibeneyo, ngakumbi itekhnoloji ethe ngqo yokwenza itekhnoloji, ubuchwephesha bezonyango kunye nebhayoloji, inokuba yindawo eshushu kuphando lwesicelo. kunye nokusetyenziswa kweteknoloji yoshicilelo lwe-3D kwixesha elizayo.

Umthamo weprinta ye-3D incinci kunye ne-desktop, ixabiso liphantsi, ukusebenza kulula, kwaye ifaneleke ngakumbi kwiimfuno zemveliso esasazwayo, ukuhlanganiswa koyilo kunye nokuveliswa, kunye nezicelo zemihla ngemihla zasekhaya.

Ukudityaniswa kweSoftware kuqonda ukudityaniswa kwe-cad/capp/rp, kwenza unxibelelwano olungenamthungo phakathi kwesoftware yoyilo kunye nesoftware yolawulo lwemveliso, kwaye iqonda eyona nto iphambili yophuhliso lwexesha elizayo lobugcisa boshicilelo lwe-3D phantsi kolawulo lothungelwano oluthe ngqo lwabaqulunqi - ukuveliswa okude kwi-intanethi.

I-3D yoshicilelo lwetekhnoloji yoshishino inendlela ende ekufuneka ihambe

Ngo-2011, imarike yoshicilelo lwe-3D yehlabathi ibiyi-US $1.71 yebhiliyoni, kwaye iimveliso eziveliswe bubuchwephesha boshicilelo be-3D zibalelwa kwi-0.02% yemveliso yemveliso yehlabathi jikelele ngo-2011. Ngo-2012, inyuke nge-25% ukuya kwi-2.14 yeebhiliyoni zeedola zase-US, kwaye kulindeleke ukuba ukufikelela US $ 3.7 billion ngo 2015. Nangona iimpawu ezahlukeneyo zibonisa ukuba ixesha lokwenziwa kwedijithali lisondela ngokucothayo, kusekho indlela yokuya kwi-3D yoshicilelo, eshushu kwakhona kwimarike, phambi kokuba izicelo zesikali semizi-mveliso zibhabhele kumakhaya. yabantu abaqhelekileyo.
