12 PARTS COMBINATION: The PEI sheet is composed of 2 parts, a spring steel platform coated with PEI surface and a magnetic rubber base plate with adhesive on the back. PEI is pre applied 2130 MAXIMUM PRINTING TEMPERATURE: A steel platform on PEI surface is placed on top. The maximum temperature for printing on the bed is 130 3GOOD ADHESION WITHOUT CURLING: When the hot bed temperature is around 60, good adhesion can be achieved, you can print directly on the PEI sheet without using any glue or other tools to help the model stick to the sheet. You don't need to worry about curling your prints at a bed temperature of 60. PETG can also be printed well, but the temperature of the hotbed needs to be around 8085 4EASY TO FALL OFF: When the temperature of the heated bed reaches room temperature, the print can easily fall off the surface. If the print is still stuck, gently flexing the plate will help to remove 5FOR VARIOUS MODELS: The platform size is 235x235mm(9.25x9.25in), suitable for Ender 3 Pro, for Ender 3 V2, for Ender 3, for Ender 3S, for Ender 3X, for Ender 5, for Ender 5 Pro, for CR 20, for CR 20 Pro and similar sized machines Item Type: Flexible Steel Platform Material: PEI, spring steel, rubber Applicable Printer: Suitable for Ender 3 Pro, for Ender 3 V2, for Ender 3, for Ender 3S, for Ender 3X, for Ender 5, for Ender 5 Pro, for CR 20, for CR 20 Pro and other 3D printers Product Size: Approx. 235 x 235mm or 9.25 x 9.25in (magnetic sticker) Installation Method: Adhesive Applicable Materials: PLA, ABS, TPU, PC, PA, etc. 1 x Platform Steel Plate 1 x Magnetic Sticker
