1、DOUBLE SIDED PRINTING: One side is sprayed with heat resistant wear resistant PEI powder, with high adhesion and wear resistance; On the other hand, there is a PEO diamond texture, and the bottom of the printed model is smooth and flat. Double sided building panels combine the advantages of PEI and textured stickers and can be switched freely 2、EASY DEMOULDING: 3D print build plate selected high strength spring steel, not only possess high flatness, but also has good elasticity, after printing, just a slight bend, you can easily demoulding the printed model in one second 3、HIGH TEMPERATURE AND HOT RESISTANT: PEI bed can withstand 260℃ nozzle without deformation, PEO surface can work at 80℃ high temperature, double handle to prevent burns, positioning hole design bring more convenient installation and use 4、FLEXIBLE AND EASY TO REMOVE: PEI and PEO spring plates are flexible. Once the build surface has cooled, the printout can be easily removed by hand, or the build plate can be bent and the printout removed. The printing pad will not deform 5、COMPATIBLE PRINTERS: 235x235mm PEI surface and PEO surface 2 hole spring plate is compatible with for Creality Ender 5 S1, for Creality K1, for Ender 5 S1, for Ender 3 S1 Pro, for Ender 3 S1, for Ender 3 V2 Neo, for Ender 3 V2, for Ender 5, for Ender 5 Pro, for CP‑01, for CR‑20 3D printers
