Remember the 3D printed working kidney I described in my previous post? Very recently, scientists have discovered a way to use 3D printers to save lives. Surgeons can now plan their approaches for specific heart surgeries by using 3D printouts of MRI scans. Since touch and feel are very important to surgeons, 3D physical models of MRI scans allow surgeons to plan in advance how they’re going to operate. It is expected that this new method can improve surgical outcomes.
