1EXCELLENT EFFECT: The surface adhesion of flexible spring steel build plate is strong, no glue is needed, cold printing can be achieved, and the printed edge is not warped, and the bottom surface of the printed product is with frosted effect, exquisite and beautiful 2EASILY DEMOLD AND DURABLE: Magnetic steel combined with PEI plate, with double ear design, easy to disassemble, gently bend the steel plate can easily take the mold. Double sided spray, both sides can be printed, the service life is twice as long as the single side 3PRINTING MATERIAL: The first layer of PEI sheet are black PEI powder spray, possess matte texture, wear resistant, not easy to scratch, can adhere to various printing materials, such as PLA, ABS, TPU, TETG, nylon, temperature resistance up to 200 4DEFORMATION RESISTANCE: The second layer of PEI sheet is a spring steel plate with good flatness. Spring steel is specially used to make springs and elastic components, has the ability to elastic deformation, difficult for human power to permanently deform 5TEMPERATURE RESISTANT MAGNETIC BASE: The third layer of 3D printer build surface is the magnetic base, made of soft magnetic rubber, possess soft texture, and has good magnetic and temperature resistance, with the back glue, can be directly affixed to the hot bed platform, long term high temperature resistance of 130, far more than the market surface temperature resistance of 70 products 6APPLICABLE MODEL: The double sided textured PEI sheet work with for Creality K1, for Ender 3, for Ender 3 Pro, for Ender 3 V2, for Ender 3 S1, for Ender 3 S1 Pro, for Ender 3 Neo, for Ender 3 V2 Neo1 x Dual Sided Textured PEIPlate1 xMagneticRubberSheet
