A medical team has carried out what is believed to be the world’s first brain transplant using a 3D printed implant. A 22-year old woman suffering from a condition that causes a thickening of the skull, had been slowly losing her vision and was suffering from motor coordination impairment, so Dr Bon Verweij of University Medical Center (UMC) Utrecht, began an in-depth study of reconstructions and 3D printing in order to replace her skull with an implant.
