Upgrade your 3D printing surface with a durable, smooth PEI spring steel sheet that delivers better adhesion, easy part release, and long-lasting performance. Ideal for heated beds and a wide range of filaments—especially PLA—this removable build surface makes first layers easier and cleanup fast.

Specifications:

• Item Type: PEI spring steel build surface
• Material: PEI-coated surface on flexible spring steel (magnetic-ready)
• Surface Finish: Smooth PEI printing surface
• Available Sizes: 180 x 180 mm (7.09 x 7.09 in), 184 x 184 mm (7.24 x 7.24 in), 214 x 275 mm (8.43 x 10.83 in), 220 x 220 mm (8.66 x 8.66 in), 230 x 257 mm (9.06 x 10.12 in), 235 x 235 mm (9.25 x 9.25 in), 241 x 253.8 mm (9.49 x 10.00 in), 257 x 257 mm (10.12 x 10.12 in), 300 x 300 mm (11.81 x 11.81 in), 310 x 310 mm (12.20 x 12.20 in), 350 x 350 mm (13.78 x 13.78 in)
• Filament Compatibility: PLA, PETG, ABS (works best with PLA)
• Operating Temperature: 40°C–80°C (104°F–176°F). Do not exceed 80°C.
• Chemical Concerns: None
• Package: 1x PEI spring steel build sheet (select size)

Key Benefits:

• Reliable Adhesion: PEI surface provides strong first-layer grip without glues or sprays.
• Easy Part Removal: Flexible spring steel lets you gently bend the sheet for quick, damage-free demolding.
• Durable & Heat Resistant: Scratch-resistant, high-temperature tolerant, and designed for repeated use.
• Double-Sided Use: Flip the sheet to extend life and maximize printing time.
• Simple Maintenance: Wipe clean with a damp cloth or isopropyl alcohol before printing.

Installation & Usage Tips:

• Leveling: For the first print, level the bed so the nozzle-to-bed distance is about the thickness of an A4 paper.
• Mounting: If included, remove the adhesive backing on the magnetic base and press the sheet flat to avoid air bubbles.
• Bed Temperature: Set bed temperature between 40°C and 80°C depending on filament (do not exceed 80°C).
• Removal: After cooling to room temperature, remove the printing surface and gently bend it to release prints.
• Magnetic Base Note: If purchasing a sheet without a magnetic base, ensure your printer already has a compatible magnetic base.
• Appearance: Slight spring steel curvature may occur from manufacturing; the magnetic base will hold it flat during use.

Compatibility: Available in many common sizes to fit a wide range of FDM heated beds and popular desktop 3D printers. Select the size that matches your printer's build plate.
