The invention belongs to the technical field of medical instruments, and discloses a 3D printing femoral head reconstruction nail which comprises a nail body with a hollow inner cavity, and the nail body is formed by 3D printing of a titanium alloy material; the nail body is provided with an implantation direction parallel to the axial direction of the nail body, the nail body is at least provided with a first section in the implantation direction, the first section is of a porous bone trabecula structure, and the porous bone trabecula structure is communicated with a hollow inner cavity of the nail body. The porous tantalum bone trabecular femoral head reconstruction rod is made of the 3D printing titanium alloy material, the titanium alloy material has good strength and ductility, the titanium alloy also has good biocompatibility, the porous tantalum bone trabecular femoral head reconstruction rod is made of the titanium alloy material through 3D printing, an existing porous tantalum bone trabecular femoral
