In yet another example of surgeons using 3D printing to plan complex surgeries, Chinese researchers have begun creating personalized models of patients' hearts. These models are based off of ultrasound scans of the organs which are then rendered precisely so that doctors can see exactly the size and detail of each unique heart. This helps in the planning and execution of surgeries, which can be prolonged and risky without apt preparation. These medical models will be helpful not just to doctors but also to medical students.

Given the resulting health and cost benefits, this application of additive manufacturing is expected to see explosive growth.
