The invention discloses a customized integral 3D printing simulating artificial finger. The customized integral 3D printing simulating artificial finger is prepared by the steps of acquiring information; reconstructing by a three-dimensional manner; performing three-dimensional reconstruction for the simulating artificial finger; mounting the artificial finger. According to the customized integral 3D printing simulating artificial finger, the model of an oral-implanted nail is determined and a customized physiological simulating artificial finger is printed by the three-dimensional technology, and therefore, the demands of a patient on functions and appearance can be met; the effect of restoring functions and aesthetics of the finger is achieved, and the simulating artificial finger can be popularized and used to national wide; the first-line patients can be treated, and meanwhile, a large number of medical treatment costs can be saved for the country, and therefore, the customized integral 3D printing simulating artificial finger is high in economic benefit and social benefit. The customized integral 3D printing simulating artificial finger has the advantages that model of the oral-implanted nail is determined and the customized physiological simulating artificial finger is printed by the three-dimensional technology, and therefore, the demands of the patient on functions and appearance can be met; the raw materials and operation are advanced, scientific, simple and practical; the wounded finger can be mounted conveniently; the purpose of saving the cost can be achieved.
