3D printing has many uses in healthcare. You can create a perfect model of a patient’s heart, lung, liver or other organ with input from CT and MRI imaging. 3D models can replicate both the inside and outside of an organ. Transparent materials reveal the vasculature and other hidden structures.
Someday, it may be possible to print actual replacement organs using a yet-to-be-perfected type of 3D printer. Until then, 3D will also be a valuable tool for medical education, as well as biomedical engineering.
