Ososayensi Buffalo eNew York eNew York bathuthukise inqubo entsha ebavumela ukuthi basebenzise ukuphrinta kwe-3D ukudala ngokushesha izinto zokwenziwa ama-hydrogel aqukethe amaseli asebenzayo. Abaphenyi banethemba lokuthi indlela yabo ingasetjenziswa esikhathini esizayo ukuphrinta kwe-3D kwezitho zabantu.
Imininingwane mayelana nale ntuthuko yashicilelwa kumagazini we-Advanced Healthcare Magazine Magazine.
Imikhawulo ekhona, kufaka phakathi ukuphrinta okulula okunezinhlangothi ezintathu, kuholele ekuxhumekeni okuphansi kwalezi "zezakhiwo" eziphrintiwe. Ubuchwepheshe obusha, obubizwa nge-Fast Hydrogel Sterolohography (Fast Hydrogel Sterohotography Ukuphrinta, ukuntanta), kunciphisa kakhulu umthwalo kumaseli ahlanganisiwe, okuyindawo evunyelwe, okuvame ukuhambisa ezinye izindlela zokuphrinta ze-3D.
Ukuphrinta kwe-3D kuhlinzeka ngamathemba amakhulu okudala izinto zokwakha ezinganxephezela ukushoda kwezitho zabanikeli, futhi abaphenyi banethemba lokuthi ngolunye usuku bamane baphambule umzimba wonke. Lo mqondo uvame ukufaka ukuphrinta kwe-matrix ehambisanayo ye-hydrogel equkethe amaseli bukhoma.
Kodwa-ke, inqubo yokuphrinta ingaba nomphumela omubi kumaseli ahlanganisiwe, kanye nesikhathi eside sokuphrinta kuhlanganisa isimo. Ngenxa yethuba lokuphrinta okusheshayo kwe-matrix ye-hydrogel, ubuchwepheshe obusha busiza amaseli bukhoma ukuze asinde kwinqubo yokuphrinta. Ubuchwepheshe obusebenza izikhathi eziyi-10-50 lapho okusheshayo kweZimboni Zezimboni kukuvumela ukuthi udale amasampula amakhulu, asetshenziselwa ukuba nzima ukufeza.
Ngenxa yokulawulwa kanzima kwezimo ze-Photopolymerization, ubuchwepheshe bungenziwa ngama-hydrogel matrices of centimeter usayizi wemizuzu. Iqembu liphinde lahlola ngempumelelo amandla okuphrinta amaseli kanye namanethiwekhi ajikelezayo asanda kujikeleza kwemithambo yegazi, okuzoba okubalulekile ekusebenzeni kahle kwezitho zomsebenzi ezenziwe nge-3D yokuphrinta. Inethiwekhi yemithambo yegazi ye-hydrogel ekwakhekeni kwe-hydrogel Vumela ikhambi lomsoco ukuze ungene kwi-log in the matrix, okuyisici esinqumayo ekutholeni izitho eziphrintiwe eziphrintiwe.
