High-precision continuous tomographic optical images of two complete specimens, male and female, were collected through milling. The specimens consist of continuous human tomographic data with no organic lesions or missing sections, and the Digital Human HD Tomographic 3D Printing Model was created using 3D printing technology.

The 3D printing model utilizes a combination of superior and inferior surfaces to print continuous sections with a standard spacing of 10 mm between sections, a section thickness of 3 mm, and a total of 175 sheets for the female specimen (350 sections) and 180 sheets for the male specimen (360 sections). The print ratio is 1.2:1. Customization of pitch and magnification is possible, with the sagittal and coronal planes to be printed later.

The Digital Human HD Tomographic 3D Printing Model offers higher definition than traditional tomographic specimens, and the milling method ensures a complete structure that is easier to identify.
