Chinese University Creates First 3D Printed Sternum
China’s Northwestern Polytechnical University has created the world’s first 3D printed sternum. The prosthesis was used to successfully treat a 54-year-old patient after surgery to remove a sternal tumor. In a process that lasted several weeks, ultrasound and 3D printing specialists from the Fourth Military Medical University’s Tangdu hospital in Xi’an created a 1:1 scale 3D printed plastic model that was an exact replica of the patient’s sternum. The hospital then commissioned the State Key Laboratory of Solidification Processing at Northwestern Politechnical University’s School of Materials Science and Engineering to 3D print an implantable titanium model.
