Creality Ender 3 PEI Sheet238mm x 238mm 3D Printer Platform Tempered Glass Plate Build Surface 3M 468MP Adhesive Transfer Tape Sheets for Creality Ender 3 or CR 20

Installation: Each sheet has a protective liner on each side of the adhesive. Simply remove the polycoated kraft paper to expose the double sided adhesive. The polyetherimide sheet comes with 3M 468MP adhesive already laminated to the PEI. Apply the PEI with slight pressure and at an angle to prevent and minimize air bubbles. Once applied set the print bed to 60C and apply pressure evenly across the PEI in a sweeping fashion to firmly set the adhesive. Please use a towel to avoid getting burned. Level the bed and set the height of the nozzle before printing. Use: Heat the bed to the desired temperatures for printing. When the print is completed, let the bed cool, and the part will be easy to release from the PEI surface. Parts are easier to remove if released before the bed becomes completely cold. Leveling the bed is very, very important when using PEI. Maintenance: clean with isopropypl alcohol between prints (or with acetone on a COLD bed). Optionally, light sanding with 600-1000 grit sand paper can be done after lots of printing to give the PEI sheet more life. Compatibility: Creality 3D printers such as Ender-3, Ender-3 Pro, Ender-3X, Ender-5, CR-20 and CR-20 Pro; confirming your printer firstly. Tips: Peel off the polycoated kraft paper liner when ready to use, and apply to clean surface. Dimensions: 238mm x 238mm (9.37 x 9.37 inches) PEI thickness: 0.4mm (0.016 inches)
