Print Bed Sheet BIQU Panda textured PEI x smooth PEI double-sided magnetic 257×257 mm for Bambu Lab P1 X1 A1

BIQU Panda double-sided magnetic print bed sheet is a 257×257 mm build surface designed for Bambu Lab P1, X1 and A1 series printers. One side features textured PEI for enhanced first-layer grip and reduced warping, while the reverse side is smooth PEI for flatter, easier-to-release finishes. The sheet attaches magnetically to compatible removable build plates, providing a stable, reusable surface for common thermoplastic filaments such as PLA and PETG that adhere well to PEI.

Advantages

The double-sided design offers two distinct surface finishes in a single accessory: textured PEI for stronger initial adhesion and improved bed-level tolerance, and smooth PEI for cleaner bottom surfaces and simpler part removal. Magnetic attachment ensures quick installation and removal without tools, and the dimensions match the build area of supported Bambu Lab models for full coverage. The PEI material is durable, chemical-resistant, and compatible with a wide range of filaments that benefit from heated-bed adhesion.

Suitable for

• Printing PLA and PETG with reliable bed adhesion on PEI surfaces
• Users who need both textured and smooth bottom finishes without changing plates
• Removable build plate workflows that require fast swap and maintenance
• Small- to medium-size parts that fit within a 257×257 mm build area

Key specifications

• Build surface type: double-sided PEI (textured on one side, smooth on the other)
• Size: 257 × 257 mm usable area
• Attachment method: magnetic removable sheet compatible with magnetic build plates
• Material properties: heat-resistant, chemical-resistant PEI suitable for common thermoplastics
• Compatible filament types: PLA, PETG and other filaments that adhere to PEI

How to use

Ensure the printer's removable magnetic build plate is clean and free of debris or residue. Align the BIQU Panda sheet with the plate edges and press gently so the magnetic backing secures the sheet in place. Choose the textured side for prints that require stronger first-layer adhesion or where surface grip is prioritized; flip to the smooth side when a flat, cleaner bottom surface and easier part removal are preferred. After printing, allow the part to cool to improve release from the PEI surface, then carefully remove the sheet if necessary for part removal or maintenance.

Usage recommendations

Clean the PEI surface regularly with isopropyl alcohol and avoid aggressive scraping; use a plastic scraper or flex the magnetic sheet (if applicable) after cooling to release parts. For optimal adhesion, set first-layer height and extrusion to recommended values for your filament, and consider light bed temperature adjustments for PETG or other materials sensitive to warping.
