We used 3D printing to construct a life-sized, detachable, high-fidelity 3D bronchial tree model with a hollow design. This design allows the bronchoscope to pass through the airway until it reaches specific bronchopulmonary segments.
The 3D-printed bronchoscopy simulator was fabricated 12 parts, a design that offers improved maintenance and cleaning capabilities. This design does not require the replacement of the whole simulator in case of damage. Instead, only specific parts are replaced when irreparable damage occurs. A customized examination could be preforming through the bronchoscopy simulator.

1. Using 3D printing to make a high-reality and high-fidelity model.
2. When the bronchoscope enters, people will see the vivid bronchial tube and feel like in real world.
3. Bronchial branches can be disassembled for bronchoscopy slicing practice, and specific branches can be replaced after completion.
4. You can customize the required microscopic examination situation and lesions, so that you will not be in chaos.
