Magnetic PEI Build Surface with Powder Coating, Stainless Steel - BambuLab BML-24044

Magnetic PEI Build Surface with Powder Coating, Stainless Steel by BambuLab is a removable print plate designed for FDM desktop 3D printers. The product combines a stainless-steel substrate with a PEI top layer and a powder-coated finish to provide a flat, durable printing face that adheres well to common filaments and detaches cleanly when prints finish. The magnetic backing allows quick attachment and removal from compatible magnetic printer bases for fast model changes and easy handling.

Advantages

The PEI top layer offers consistent first-layer adhesion across materials commonly used in desktop 3D printing, while the stainless-steel core ensures dimensional flatness and resistance to bending. The powder-coated finish improves surface durability and reduces visible wear. The magnetic design provides secure mounting without tools and simplifies plate swaps, and the printable surface supports straightforward part removal with minimal risk of damage to the model or the plate.

Suitable for

• Desktop FDM 3D printers with compatible magnetic build bases
• Prototyping and rapid iteration of plastic parts
• Printing with PLA, PETG and other common thermoplastics
• Users who require quick plate changes and easy post-processing

Key specifications

• Construction: stainless-steel substrate with PEI top layer and powder-coated finish
• Attachment: magnetic removable backing for compatible bases
• Surface: PEI for improved adhesion and repeatable print quality
• Durability: powder coating for scratch and wear resistance
• Compatibility: designed for common FDM filaments such as PLA and PETG

How to use

Place the magnetic build surface onto the printer's matching magnetic base, ensuring full contact across the plate to avoid warping during printing. Prepare your printer bed leveling or automatic calibration procedure as required by your printer model. Start with a clean surface—remove dust, oils, or residues before printing; a wipe with isopropyl alcohol on a lint-free cloth is recommended. After printing, allow the plate and part to cool to room temperature when possible to ease removal; gently flex the plate if designed to do so or use a removal tool compatible with PEI surfaces.

Usage recommendations

For consistent results, clean the PEI surface regularly with isopropyl alcohol and avoid abrasive cleaners. Use moderate print temperatures recommended for each filament type and allow cooling time before removing prints. Store the plate flat and avoid sharp impacts to the powder-coated surface to maintain long-term performance.
