The PEI Removable Magnetic Flexible Heated Bed Platform is mainly divided into 3 layers: [1] The first layer is made of PEI material. Amber color, smooth surface, good adhesion to various printing materials, especially PLA and ABS, high temperature resistance. [2] The second layer is a flexible steel plate, which is specially used to make springs and flexible elements, has a strong deformability. [3] The third layer is magnetic base,which is made of soft magnetic rubber, soft in texture, and has good magnetism and temperat,bure resistance. With 3M adhesive, it can be directly attached to the heated bed platform. The surface adhesion of PEI Magnetic Flexible Heated Bed is strong, no glue and tape is needed, cold printing can be realized, and the bottom surface of the printed product is smooth. And the combination of magnet and steel makes it easy to remove parts with no damage, by just gently bending the steel plate .
