PET-PEI Double-sided Spring Steel Print Sheet 235x235mm (No Base)

Product Description

The PET-PEI Double-sided Spring Steel Print Sheet 235x235mm (No Base) is a premium dual-texture build surface engineered for 3D printing enthusiasts who want the flexibility of two distinct bottom-layer finishes in a single plate. Precision cut to a 235x235mm profile, this high-grade spring steel sheet drops perfectly onto standard heated beds. Because it does not include a magnetic base adhesive, it is designed as a direct replacement or an alternative plate for makers who already have an existing magnetic sticker installed on their machine.

This build plate offers a high-performance double-sided interface. One side features a sophisticated PET film coating that transfers a striking, ultra-smooth holographic carbon fiber geometric pattern directly onto the bottom layer of your prints—ideal for visible structural plates, custom electronics faceplates, or aesthetic machine components. The reverse side is coated with a robust, textured PEI (Polyetherimide) powder layer, providing legendary adhesion for everyday printing. PEI grips materials tightly while hot and releases them effortlessly once cooled, making it excellent for long-duration mechanical part prints.

Built on a core of premium flexible spring steel, the plate resists permanent deformation or warping under extreme bed temperatures. Once your print job is complete, simply let the plate cool down, give the spring steel a gentle flex, and your parts will detach instantly without the need for scrapers or chemicals. It is a vital upgrade for achieving professional, flaw-free first layers across a wide range of engineering filaments.

Key Features

• Dual-Texture Surface: Features an ultra-smooth PET carbon fiber pattern on one side and a classic, textured powder-coated PEI surface on the other.

• Premium Spring Steel Core: Built from high-tensile spring steel that stays perfectly flat under thermal stress and flexes easily to release finished prints.

• Holographic Texture Transfer: The PET coating transfers a beautiful, high-tech carbon fiber matrix texture directly onto the base of your 3D printed objects.

• High-Temperature Performance: Both sides are rated to withstand standard bed temperatures required for processing advanced workshop materials.

• No Magnetic Base Included: Intended as a cost-effective swap-out sheet for 3D printer beds that already feature an existing magnetic platform setup.

Applications

• Upgrades and drop-in replacements for 235x235mm beds such as the Creality Ender 3 series (Ender 3 V2, V3, V3 SE, V3 KE, K1) and similar platforms.

• Creating unique bottom-layer patterns on structural toolheads, custom enclosures, and visible mechanical brackets.

• Enhancing first-layer adhesion for challenging materials like PLA, PETG, TPU, and ABS without using glue sticks or hairspray.
