A 3D-printed artificial vertebral body, comprising a first support assembly (10) and a second support assembly (20) connected to the first support assembly. The first support assembly (10) and the second support assembly (20) extend through the upper surface and the lower surface of the 3D printed artificial vertebral body. The first support assembly (10) is disposed on the rear side of the 3D printed artificial vertebral body. The first support assembly (10) is a U-shaped structure curving inwards towards the middle of the 3D printed artificial vertebral body. A gap between the first support assembly (10) and the second support assembly (20) is provided with a filling body composed of a plurality of micropores having a diameter of 0.2-2 mm and a porosity of 60%-80%. The 3D-printed artificial vertebral body has a large adjacent vertebral body contact area, and has a normal vertebral body buffering effect, and the high porosity micropores increase the ingrowth of adjacent vertebral body tissue and cavity implanted bone tissue.
