BIQU dual-sided magnetic build plate — textured PEI on one side, smooth PEO on the other — for Bambu Lab P1 X1 A1 — 257×257 mm

BIQU dual-sided magnetic build plate sized 257×257 mm provides two distinct build surfaces — textured PEI on one side for enhanced adhesion and a smooth PEO finish on the other for easier part release and cleaner bottom surfaces. Designed to fit Bambu Lab P1, X1 and A1 printers, the plate uses a magnetic backing for fast mounting and removal, enabling quick bed changes and consistent positioning. The surface combination supports a range of common filaments and simplifies workflow for both everyday prints and occasional larger parts.

Advantages

The textured PEI side offers reliable first-layer adhesion for materials such as PLA and PETG, reducing warping and improving print stability without additional adhesives. The smooth PEO side delivers low-friction release and smooth part undersides, which is useful for delicate features and decorative surfaces. The magnetic backing ensures secure attachment to the printer heatbed while allowing fast removal for post-processing or cold peels. The 257×257 mm size matches the specified build area of compatible Bambu Lab models to maintain alignment and repeatability.

Suitable for

• Printing standard filaments such as PLA and PETG
• Projects requiring either strong first-layer adhesion or easy part release
• Rapid bed swaps and multi-stage workflows
• Users who prefer dual-surface versatility without changing plates

Key specifications

• Build plate dimensions: 257 × 257 mm
• Dual-sided surfaces: textured PEI on one side, smooth PEO on the other
• Magnetic backing for secure mounting and quick removal
• Compatible with Bambu Lab P1, X1 and A1 printer build areas
• Surface suited to common filaments including PLA and PETG

How to use

Attach the magnetic build plate to the printer heatbed, ensuring it seats flat and aligns with the bed edges. Choose the textured PEI side when you need stronger first-layer adhesion; flip to the smooth PEO side when easier part removal or a smoother part bottom is desired. Level the bed or run an auto-level routine if required by your printer after installing the plate. After printing, allow the plate and part to cool to room temperature before removing to reduce the chance of deformation; for tight parts, gently flex the plate or use a cold peel technique.

Usage recommendations

Clean the plate regularly with isopropyl alcohol to remove oils and residues. For PETG use, monitor adhesion and consider a light release agent on the textured side if parts stick excessively. Avoid sharp tools that can scratch the PEI/PEO surfaces; use plastic scrapers designed for removable plates.
