Creality Sermoon D3 PEI-jousiteräslevysarja

For Creality Sermoon D3 owners who want reliable first-layer adhesion and effortless print removal, this PEI spring steel plate kit is a practical upgrade. The flexible magnetic build surface replaces the stock bed with a dual-sided PEI-coated steel sheet that grips filaments firmly during printing and releases them cleanly when flexed. No scrapers, no glue sticks—just bend, pop, and print again.

Key specifications

• Compatible with Creality Sermoon D3 3D printer
• Build surface: textured PEI on one side, smooth PEI on the other
• Plate material: flexible spring steel, 0.4 mm thick
• Magnetic base sticker: 1.5 mm thick, adhesive backing
• Plate dimensions: 200 x 200 mm
• Maximum bed temperature: 120°C
• Works with PLA, PETG, ABS, TPU, wood-filled, carbon fiber, and more
• Included: 1x PEI spring steel plate, 1x magnetic base sticker

Why choose it

The dual-sided PEI surface gives you flexibility: use the textured side for strong adhesion on tricky materials, or the smooth side for a glossy bottom finish. Spring steel returns to flat after bending, so prints pop off without damage. The magnetic base holds the plate securely during high-speed movements, yet allows quick removal for cleaning or swapping.

Ideal use cases

• Everyday printing of functional parts and prototypes
• Materials that need extra bed adhesion, like PETG or ABS
• Users tired of scraping prints off a fixed bed
• Workshops and classrooms with multiple filament types

Good to know

Installation takes minutes: peel the adhesive backing from the magnetic sticker, apply it to the heated bed, and let the spring steel plate snap into place. Clean the PEI surface with isopropyl alcohol between prints to maintain adhesion. Avoid using metal tools on the PEI coating to prevent scratches.
