The present application relates to the technical field of shock absorption, and discloses a precision stabilizing and shock absorbing support structure of a 3D printer, which comprises a printing mechanism, a first hydraulic device, a control panel, a printing table and a main body frame. In the present application, the stress structure is balanced left and right under the support of the blocking plate. At this time, the stress structure generates counterclockwise upward prying force on the blocking plate. The blocking plate supports the upward prying force of the stress structure and absorbs the vibration generated in the movement of the stress structure, thereby forming the effect of supporting the movement of the printing head and absorbing the vibration. The stress bar is supported on the inner side of the shell under the elasticity of the elastic layer. When the stress bar and the inner side of the shell move and rub, the elastic layer absorbs the resonance force, so that the shock absorbing rod absorbs the vibration force of the guide frame moving up and down on the round rod, thereby avoiding the vibration influence on the horizontal and vertical movement of the printing head, and preventing the problem of inaccurate printing of the 3D printing product caused by friction resonance.
