Scientists 3DIt’s a staple feature in many science fiction blockbusters, and now scientists have dev

eloped a fully 3D printed bionic eye for the first time. Researchers from the University of Minnesota printed an array of light receptors on a hemispherical surface. And they believe that the bionic eye could soon let blind people see, or sighted

see better. Dr Michael McAlpine, co-author of the study, said: “Bionic eyes are usually thought of as science fiction, but now we are closer than ever using a

multimaterial 3D printer.” Read MoreRelated ArticlesHow has technology changed? The biggest advancement
