Abacwaningi e-UC Davis baye bahlakulela okungajwayelekile uhlobo olusha lokuphrinta kwe-3D esebenzisa i-Droplet-Based Multiphase Emulsion.
Enye yezinselelo ezinkulu ekuphrinteni kwe-3D ukungakwazi ukuphatha izinto eziningi. Amaphrinta ajwayelekile e-3D anamuhla angaphrinta i-3D into eyodwa ngesikhathi, ngamamodeli athile athuthuke kakhulu akwazi ukuphrinta ngedlanzana elincane lezinhlobo ezahlukene.
Lokhu ngokuvamile akusizi ngangokunokwenzeka, njengoba izinto ezisebenzayo ezijwayelekile zakhiwe ngezinto eziningi. Ngokuvamile izinto ezihlukene zikhethwa ngoba zinikeza izakhiwo zobunjiniyela ezihlukene zezingxenye ezahlukene zento. Isibonelo, into eqinile ingase yakhe ikesi, kuyilapho into ethambile yerabha ingase yakhe ungqimba lokubamba ekesini.
Omunye wabacwaningi be-UC Davis, uJiandi Wan, uphawule ukuthi imibhobho esetshenziswa ekunyatheliseni i-3D yayifana ncamashi naleyo esetshenziswa emishinini ye-microfluidics, kodwa ukuthi yayingajwayelekile. U-Wan uzibuze ukuthi ingabe imibhobho ye-microfluidics eyinkimbinkimbi ingase isetshenziswe ekuphrinteni kwe-3D.
Kuvele ukuthi bangakwazi.
I-Droplet-Based Multiphase Emulsion
Ocwaningweni, abacwaningi bakwazi ukwengeza umbhobho omncane we-capillary ohlelweni lokuphrinta lwe-3D. Le mishini ikwazile ukuletha amanani alawulwayo amaconsi wento yesibili ekusakazeni okubalulekile. Amaconsi ayemancane ngokwanele ukwakha i-emulsion lapho efakwa.
Ngokushintsha inani kanye nesikhathi samaconsi, abacwaningi bakwazi ukuguqula izakhiwo zokuphrinta kwe-3D okwaba umphumela.
Isibonelo, bakwazi ukulawula ukuqina kwezinto, bakwazi ukukhiqiza ububanzi bokuthambile ngaphakathi kokuphrinta ngokufunwa. Isistimu ngokusobala ingamukela "amaconsi ensimbi enamanzi nawuketshezi", iphakamisa ukuthi izici ezihlukahlukene ezihlukene zinganikwa amandla ngaphakathi kokuphrinta kwe-3D kusetshenziswa le ndlela.
Eqinisweni, ephepheni bathi:
"Ukusetshenziswa kwe-microfluidics yenhlanganisela ye-inki eyi-multiphase noma immiscible (okungukuthi, ama-emulsions) kumongo wokuphrinta we-3D kusalokhu kungahlolisiswa."
Ukuhlola kwabo kuleli qophelo kubonakala kusekuthuthukiseni izindlela ezisebenzayo zokuphrinta kwe-3D izinto eziguqukayo eziguquguqukayo, kanye nokwengeza izici ze-ferric, okuwumsebenzi omkhulu. Nokho, ngisola ukuthi le ndlela ingase ibe nemiphumela ejule kakhulu.
Ukuphrinta kwe-Microfluidic 3D
Kunemibono embalwa ethokozisayo lapha.
Okokuqala, cabanga nge-3D iphrinta into, kodwa inekhono lokuhluka ngokuqhubekayo ubulukhuni bento. Angicabangi ukuthi izinto ezinjalo zikhona nanamuhla, kodwa uma indlela yokuzenza ibithandwa, besizibona yonke indawo.
Angase abe nemiklamo ekhumbuza izakhiwo zanamuhla ezifana negwebu ezikhiqizwe amasistimu e-FEA, ngaphandle kokubonakala kuqinile kodwa kube nokugeleza okuyinkimbinkimbi okuguquguqukayo okugeleza ngaphakathi. Isofthiwe entsha yokuhlaziya ingase idingeke lapha, kunjalo.
Manje cabanga ngokuqhubekayo lapho le ndlela yokunyathelisa ye-3D ikwazi ukulawula hhayi kuphela ukuguquguquka kodwa nezinye izakhiwo zobunjiniyela ngokungeza amaconsi ahlukene nokudala ama-emulsion angavamile. Ingxenye yokuphrinta ingaba kazibuthe, enye eguquguqukayo, enye i-conductive, esobala, njll. Uthola umbono.
Futhi, sizodinga isofthiwe entsha neyinkimbinkimbi kakhulu ukuze silawule lawo mandla amangalisayo.
Into eyodwa:
Ngenkathi ababhali baleli phepha kungu-Hing Jii Mea, uLuis Delgadillo, noJiandi Wan, leli phepha liphinde lithi:
"Ihlelwe nguJoseph M. DeSimone".
UDkt. DeSimone akayena omunye ngaphandle komsunguli we I-Carbon, enye yezinkampani ezihamba phambili ezikhiqiza amaphrinta e-3D.
Kazi lobu buchwepheshe bungase buyephi.
