IYunivesithi yaseDlufalo eNew York iqulunqa indlela entsha ebavumela ukuba basebenzise i-3D yokuprinta ukuba badale ngokukhawuleza iiseli ezifanelekileyo. Abaphandi banethemba lokuba indlela yabo inokusetyenziswa kwikamva lokushicilelwa kwe-3D yamalungu omntu.
Ulwazi malunga nolu phuculo lwapapashwa kwiMagazini yezempilo ehambileyo.
Izithintelo ezikhoyo, kubandakanya ukuprinta okucothayo ezintathu, khokelela kusetyenziso oluphantsi lwento "yokushicilela". Itekhnoloji entsha, ebizwa ngokuba yi-Hydrogel Stereoografi (ikhawuleza i-Hydrogel Stereoography, i-FARAT), inciphisa kakhulu umthwalo kwiiseli ezingeyo-3, eziqhele ukushicilelwa kwe-3D.
Ukuprintwa kwe-3D kunika amathemba amakhulu okudala izixhobo ezinokuhlawula ukunqongophala kwamalungu afanelekileyo, kwaye abaphandi banethemba lokuba ngenye imini banokuyithetha nje umzimba wonke. Le ngcinga ihlala ithetha ukuprintwa kwe-biompaal matrix equlethe iiseli ezihlala.
Nangona kunjalo, inkqubo yokuprinta inokuba nefuthe elibi kwiiseli ezingeyo-zikweni, kwaye ixesha elide lokuprinta linengxaki kuphela. Ngenxa yokuprinta ngokukhawuleza kwe-hydrogel matrix, itekhnoloji entsha inceda iiseli zokuphila ukuze ziphile kwinkqubo yokuprinta. Itekhnoloji isebenza amaxesha ali-10-50 ixesha elikhawulezayo lomgangatho wemveliso likuvumela ukuba wenze iisampulu ezikhulu, ezazisetyenziselwa ukuba nzima ukufezekisa.
Enkosi kulawulo olunzima lweemeko zefotpolymerization, itekhnoloji inokwenziwa nge-hydrogel matricters yesayizi yesentimitha kwimizuzu. Eli qela liye lavavanya ngempumelelo indlela yokuprinta iiseli kwaye yakhelwe-ukujikeleza uthumo lwemithambo yegazi, eya kuthi kubaluleke kakhulu ekusebenzeni kwe-3D. Inethiwekhi yemithambo yegazi yokufakelwa kwizakhiwo ze-hydrogel zivumela isisombululo sesondlo ukuze ungene kwilog kwi-matrix, enesigqibo sokufumana amalungu aprintayo.
