A pair of doctors from Australia's Peninsula Health have been exploring ways to better help their patients understand the nature of their injuries or health issues by using 3D printed models as visual aids. They use MRI and CT scan data to 3D print exact copies of patients tumors or even detailed recreations of their broken bones before they have surgery to help them understand what will happen before and even after the surgery. For instance if they have a tumor on their jawbone, the doctors can print that and then use software to remove the tumor and print a second jawbone that can be compared to the first.
