　　Objective To explore the method of establishing 3D reconstruction model of minipig lung and the application of 3D printing model.

　　Methods Four Bama minipigs were subjected to general anesthesia for pulmonary CT angiography. The data were obtained by using MIMICS software to reconstruct the tissue structure of lung segments, and 3D printing of the pulmonary vascular solid model.

　　Results The three-dimensional model reconstructed based on CT angiography data clearly showed the anatomical structure of the 3-4 branches of the pulmonary blood vessels and bronchi in miniature pigs, and showed lobe fissures and some intersegmental planes, which could be rotated and zoomed arbitrarily.

　　Conclusion Using 3D reconstruction and 3D printing technology, the anatomical model of the Bama minipig lung can be successfully created, which provides a basis for comparative medical research and training materials for thoracic surgery.
