Build Surface Plate BIQU Panda Textured PEI x Smooth PET CF double-sided magnetic 257×257 mm for Bambu Lab P1 X1 A1

BIQU Panda textured PEI x smooth PET CF double-sided magnetic build surface, sized 257 × 257 mm, is a replacement build plate compatible with Bambu Lab P1, X1 and A1 printers. One side offers a textured PEI finish that improves bed adhesion and produces a matte first layer, while the reverse side features a smooth PET CF surface for glossy or easier-release prints. The plate uses a magnetic backing for quick attachment and removal, enabling fast part removal and convenient handling between prints.

Advantages

The double-sided design delivers two distinct surface finishes without additional adhesive or treatment: textured PEI for strong first-layer grip and smooth PET CF for low-friction, clean-release surfaces. The magnetic mounting system ensures stable positioning during printing and rapid detachment after cooling. The 257 × 257 mm printable area matches the specified build dimensions of compatible Bambu Lab models, providing full-coverage printing for common part sizes. The materials used are suitable for common filaments such as PLA and PETG and maintain consistent surface characteristics over multiple print cycles.

Suitable for

• Printing PLA parts that benefit from matte textured first layers
• Producing PETG and similar filament parts where smooth underside finish is preferred
• Users who need quick bed removal and easy part release via magnetic attachment
• Small to medium sized models that fit within a 257 × 257 mm build area

Key specifications

• Build plate dimensions: 257 × 257 mm printable area
• Double-sided surfaces: textured PEI on one side, smooth PET carbon-fiber reinforced on the other
• Magnetic backing for removable attachment
• Compatible with PLA, PETG and similar thermoplastic filaments
• Designed for desktop FDM printers with matching mount and size

How to use

Attach the magnetic build plate to the printer's metal carrier plate, ensuring correct alignment and full contact of the magnetic backing. Choose the desired side based on required first-layer finish: textured PEI for stronger adhesion and matte appearance, or smooth PET CF for easier part release and glossier undersides. Level the bed or adjust the Z-offset according to your printer's calibration procedure to account for the new surface thickness. Preheat the bed and nozzle to filament-recommended temperatures before starting the print, and allow the plate to cool before removing prints for easier separation.

Usage recommendations

Clean the build surface periodically with isopropyl alcohol to remove oils and residue; avoid abrasive cleaners that could damage the textured PEI or smooth PET CF surfaces. For very high-adhesion prints, a light application of glue stick or specialized adhesives may be used sparingly on the textured side. Store the plate flat and protect from sharp tools when removing parts to preserve surface integrity.
