Features: 1.DOUBLE SIDED DESIGN: One side is smoothly carbon fiber PEI bed, the bottom of the printed model is smoothly, easy to disassemble and clean, the other side is PEI frosted surfaces, strong adhesion with the model and prints, will not be deformed. 2.ENHANCED MAGNETIC ADHESION: The PEI sheet is made of thicker steel plate, which enhances magnetic adhesion, prevents warping, and is resistant to heat and abrasion. The PEI coated bed surfaces is resistant to high temperatures up to 260C and provides better adhesion. 3.RICH DESIGN: 3D printer PEI build plate textured/smoothly design can meet different printing needs, the textured surfaces is more matte and the smoothly surfaces is more delicate. 4.COMPATIBILITY: PEI flexible steel platform can print most filament such as PLA/ABS/PETG/TPU/Nylon, for Bambu Lab P1P, P1S, X1C Printers. 5.EASY TO INSTALL: Stick the soft magnetic base on the heated bed of the 3D printer, then place the stacked PEI steel foil platform on the top and it is prepare to use, easy to operate. specification:Item Type: Double Sided Build Plate 257x257mm Material: Steel Application: for Bambu Lab P1P, P1S, X1C Printers PackageList:1 x DoubleSidedBuildPlate257x257mm NoteRemove the clear protective film from the surfaces before use
