The invention relates to a silicone rubber ordered porous material with a wide stress platform area, a workpiece and a preparation method. The micro-pore structure of the silicone rubber ordered porous material at least comprises a basic structure layer. Each basic structure layer comprises two unit wall layers stacked mutually. Each unit wall layer internally comprises a plurality of silicone rubber strip sets arranged in parallel and at equal intervals. Each silicone rubber strip set is composed of at least two silicone rubber strips stacked in the vertical direction in a laminating mode. The silicone rubber strip sets of every two adjacent unit wall layers are overlapped, and an included angle x is formed, wherein x is larger than 0 but smaller than or equal to 90 degrees, and the included angle is preferably 90 degrees. The silicone rubber ordered porous material with the micro-pore structure is prepared by combination with a 3D printing technology and expresses excellent wide platform area characteristics in a uniaxial compression state, thereby having an excellent buffer energy-absorbing effect and having broad application prospects in the fields of precise component positioning, packaging materials, movement protection, national defense equipment and the like.
