Emzamweni wokwenza ukukhiqizwa kwezinto eziphilayo kufinyeleleke kalula, abacwaningi eNyuvesi yaseCalifornia, eBerkeley bahlanganisa i-2D bioprinting, ingalo yerobhothi yomhlangano we-3D, kanye nokuqandisa kwe-flash ngendlela engavumela ngolunye usuku ukuphrinta kwezicubu eziphilayo ngisho zonke izitho zomzimba. Ngokuphrinta izitho zibe amashidi amathishu amancane, bese uwaqhwaza futhi uwabeke ngokulandelana, ubuchwepheshe obusha buthuthukisa ukusinda kwama-biocell kokubili ngesikhathi sokuphrinta nangesikhathi sokugcinwa okulandelayo.
I-Biomatadium inamandla amakhulu emithi yesikhathi esizayo. Ukuphrinta kwe-3D kusetshenziswa ama-stem cells esiguli kuzosiza ukudala izitho zokufakelwa ezihambisana ngokugcwele futhi ezingeke zidale.
Inkinga iwukuthi izindlela zamanje ze-bioprinting zihamba kancane futhi azikhuli kahle kakhulu ngoba amangqamuzana akuthola kunzima ukusinda enqubweni yokunyathelisa ngaphandle kokulawula okuqinile kwezinga lokushisa nendawo yamakhemikhali. Futhi, ubunkimbinkimbi obengeziwe bubekwe ngokuqhubekayo ukugcinwa nokuthuthwa kwezindwangu eziphrintiwe.
Ukuze linqobe lezi zinkinga, ithimba laseBerkeley lanquma ukufanisa inqubo yokunyathelisa futhi liyihlukanise ngezigaba ezilandelanayo. Okusho ukuthi, esikhundleni sokuphrinta isitho sonke ngesikhathi esisodwa, izicubu ziphrintwa kanyekanye ezendlalelo ze-XNUMXD, ezibekwa phansi ngengalo yerobhothi ukudala isakhiwo sokugcina se-XNUMXD.
Le ndlela isivele isheshisa inqubo, kodwa ukunciphisa ukufa kwamangqamuzana, izingqimba zicwiliswa ngokushesha kubhavu we-cryogenic ukuze ziqandwe. Ngokusho kweqembu, lokhu kuthuthukisa kakhulu izimo zokusinda kwezinto eziphrintiwe ngesikhathi sokugcinwa nokuthutha.
βOkwamanje, i-bioprinting isetshenziswa ngokuyinhloko ukuze kwakhiwe izicucu ezincane,β kusho u-Boris Rubinsky, uprofesa wobunjiniyela bemishini. βInkinga nge-3D bioprinting ukuthi iwuhlelo olunensayo, ngakho-ke ngeke ukwazi ukuphrinta noma yini enkulu ngoba izinto zebhayoloji zizofa lapho usuqedile. Enye yezinto zethu ezintsha ukuthi simisa izicubu njengoba siziphrinta, ngakho-ke izinto zebhayoloji ziyagcinwa."
Ithimba liyavuma ukuthi le ndlela ye-multilayer yokuphrinta kwe-3D ayintsha, kodwa ukusetshenziswa kwayo kuma-biomaterials kuyashintsha. Lokhu kuvumela izingqimba ukuba ziphrintwe endaweni eyodwa bese zithuthelwa kwenye ukuze zihlanganiswe.
Ngaphezu kokwenza izicubu nezitho, le ndlela inezinye izinhlelo zokusebenza, njengokukhiqizwa kokudla okuqandisiwe esikalini sezimboni.
