1、APPLICABLE MODELS: PEI sheet is suitable for 3D printers with print size of 235x235mm, such as for ENDER3 3s pro V2, for Aquila, for Neptune 3 pro 4 and other models. 2、EASY TO USE: Simply attach the magnetic base plate to the heated bed and place the steel platform with PEI surface on top. The maximum temperature of the print bed is 130℃. 3、HEAT RESISTANT: PEI is excellent when used in 3D printing applications because it can withstand the many thermal cycles that the 3D print bed goes through from print to print. 4、EXCELLENT ADHESION: Excellent magnetism, adhesion and elasticity. The printing surface can effectively adhere to a variety of printing materials. It prevents edges warping better than conventional 3D printer beds. You can easily remove the print model by slightly bending it, which is both efficient and useful. 5、DURABLE MATERIAL: PEI sheet is made of premium spring steel, PEI surface, matte surface has strong high temperature stability, high printing stability, flame retardant, high temperature resistance, high strength and other properties, flexible and removable, not easy to deform.
