Spring Steel Plate Flexible Magnetic Sticker offers a 235x235mm heatbed solution for 3D printers. It uses a durable spring steel plate that is flexible, detachable, and magnetically adherent, with high-temp resistance up to 140°C and short-term 180°C for PC material. It provides fast heating, easy model removal, warp-free printing, compatibility with hot bed or glass platform, and easy replacement. It supports PLA/ABS and other filaments, with no glue required and simple first-layer setup.

• Flexible, detachable spring steel plate that resists deformation and rust
• Magnetic base withstands high temperatures (up to 140°C) and maintains magnetism beyond 130°C, suitable for PLA, ABS, PC, and more
• 235x235mm size for easy operation and broad print compatibility
• No glue required; printing is warp-free and prints are easy to remove by flexing the plate
• Can be installed on hot bed or glass platform; two-sided A/B board with easy model removal
• PC-based construction offering flame retardance, wear resistance, oxidation resistance, and dimensional stability

Double Sided PEI Sheet on a 330x330mm powder-coated spring steel base offers two surfaces for versatile 3D printing: a textured PEI side for strong adhesion on challenging prints and a smooth PEI film side for flawless finishes. The plate is flat, rust-resistant, and sturdy, with magnetic 3M adhesion for quick installation. It withstands high temperatures (up to 200°C on the PEI surface) and supports a wide range of materials, with easy print removal by slight flexing and even heat distribution.
