Feature: 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. HEAT RESISTANT MATERIAL: PEI PEO build plate is made of spring steel and polyethylene material, with flame retardant, low smoke, high strength, good heat resistance 3. EXCELLENT FLATNESS: The 3D printer mini build sheet provide the smoothest build surface on the market, ensuring high flatness at the bottom of the print, ensuring that the model is firmly attached to the print platform surface 4. EASY TO DISASSEMBLE: The textured smooth build plate strip the top section from the hot bed and bend to easily remove the model because is flexible 5. COMPATIBLE PRINTER: Textured PEI smooth PEO build plate is suitable for Bambu mini 3D printer, used as heated bed spring steel flexible platform Specification: Item Type: PEI PEO Build Plate Material: Spring steel and polyethylene Size: Approx. 180 x 180mm / 7.09 x 7.09in Application: For Bambu mini. Package List: 1 x PEI PEO Build Plate Note: 1. The first print must be leveled (the distance between the nozzle and the hot bed is generally the thickness of an A4 paper). 2. When sticking on the hot bed platform, ensure it is flat and free of bubbles. 3. Adhere the PEI or PEO surface spring steel plate to the magnetic base. 4. Start printing, the hot bed temperature can be set between 40℃‑80℃ according to actual conditions (do not exceed 80℃). 5. Remove the printed surface, gently bend to easily demold.
