FlashForge Creator 4 Spring Sheet Assembly - Flexible PEI Build Plate

For FlashForge Creator 4 owners who want reliable adhesion and effortless print removal, the Spring Sheet Assembly is a direct replacement flexible build plate. Its spring steel sheet with PEI surface drops onto the printer's magnetic base, giving you a smooth, heat-resistant platform for a wide range of filaments.

Key specifications

• Print surface material: PEI (Polyetherimide)
• Build plate material: Spring steel
• Print surface dimensions: 400 x 350 mm
• Adhesion method: Magnetic (requires magnetic base on printer)
• Print removal method: Flex-off removal
• Heat resistance: Designed for heated beds
• Thickness: Approx. 2 mm
• Colour: Black (PEI surface)

Why choose it

The PEI surface provides strong first-layer adhesion, reducing warping and failed prints. After printing, simply flex the spring steel sheet to pop parts off cleanly—no scraping or prying. The sheet is durable and easy to clean with isopropyl alcohol, keeping your build surface in top condition.

Ideal use cases

• Printing with PLA, PETG, ABS, TPU, Nylon, and other common FDM filaments
• High-temperature applications on the Creator 4's heated bed
• Quick turnaround between prints thanks to fast part removal

Good to know

This spring sheet assembly is a drop-in replacement for the original FlashForge Creator 4 build plate. It requires the printer's magnetic base (already present on the Creator 4). The PEI coating is black, and the sheet is approximately 2 mm thick overall.
