The utility model provides an artificial bone, comprising bionic bone, supporting pillar and 3D porous scaffold structure； said supporting pillar and said 3D porous scaffold structure are connected to said bionic bone, said 3D porous scaffold structure is set to cover said supporting pillar. Advantageous result of the utility model is: use artificial bone to replace original bone, set supporting pillar and 3D porous scaffold structure in the meantime, supporting pillar gets into coupling end which connected to original bone to work as support and fixing. Set the 3D porous scaffold structure on the periphery of coupling end which connected to original bone, to provide space for the adhesion and growth of bone cells, make the connection between artificial bone and original bone more stable.
