The personnel of Biying Bio 3D real-time printing team quickly scanned the injured part's data and printed the brace for the athlete.

The reporter learned that the Iranian skydiver's fracture fixation is a black technology called "fast 3D printed external fixation limbs."

According to Li Feng, this high-speed 3D printed medical external fixation brace was developed by a technology company in Wuhan and is suitable for external fixation of fractures, deformities and traumas. In the operation, the doctor took only a few seconds to perform a 3D scan to obtain the accurate model data of the patient's injury.
