Masayendisiti yunivhesiti Buffalo muNew York akatanga hunyanzvi hutsva hunovatendera kuti vashandise kudhinda 3D kukurumidza kugadzira hydrogel zvinhu zvine masero anoshanda. Vatsvagiri vanotarisira kuti nzira yavo inogona kushandiswa mune ramangwana rekudhinda 3D kudhinda kwembudzi dzevanhu.
Ruzivo pamusoro pekukura uku rwakabudiswa mune yehutano hwehutano hwehutano hwemagazini yemagazini.
Zviratidzo zviripo, kusanganisira kudhinda-matatu-matatu ekudhinda, kutungamira kuderera kwekuvimbwa kwe "zvivakwa" zvakadhindwa ". Tekinoroji nyowani, inonzi Fast Hydrogel Stereolithography (Fast Hydrogel StereolitHography Cholling, inoderedza mutoro pamasero akagonesa, iyo inogonesa, iyo inowanzoita dzimwe nzira dzekudhindwa kwe 3D kudhinda.
Kudhinda 3D kunopa tarisiro yakakura yekugadzira zvinhu zvinogona kudzorera kushomeka kwemitezo yezviratidziro, uye vanotsvaga vanotarisira kuti rimwe zuva vanogona kungo printe muviri wese. Pfungwa iyi kazhinji inoreva kudhinda kweiyo biocompable hydrogel matrix iyo ine mararamiro emararami.
Nekudaro, maitiro ekudhinda anogona kuve nemhedzisiro yakaipa pamasero akajeka, uye nguva yakareba yekudhinda ichingomesa mamiriro acho ezvinhu. Nekuda kwekuti mukana wekudhindisa nekukurumidza kweiyo hydrogel matrix, tekinoroji nyowani inobatsira masero ekurarama kuti ararame mukudhinda. Iyo tekinoroji inoshanda 10-50 Times nekukurumidza kweiyo maindasitiri standard standard inotendera kuti ugadzire ma samples hombe, iyo yaimboita kuti iome zvakanyanya kuzadzisa.
Kutenda kune zvakaoma kudzora kwemamiriro ezvinhu eiyo photopolymerization, iyo tekinoroji inogona kugadzirwa nehydrogel matrices yemakumi emakore. Chikwata chakabudirira zvakare kuyedza kugona kwekudhinda uye kwakavakirwa-mukudzikira mitezo yemidziyo yeropa, iyo ichave yakakosha pakubata kwakakodzera kwe nhengo dzakagadzirwa neiyo 3D yekudhinda nzira yekudhinda. Network yemidziyo yeropa muHydrogel Sharuru dzinobvumira mhinduro yemutengesi kuti ipinde penji mune iyo matrix, iyo chinhu chinonzwisisika pakuwana nhengo dzakadhindwa dzakadhindwa.
