### Two-in-one Dual Different Functional Surfaces One side is anti-wear PET carbon fiber textured layer, reverse side is granular gold PEI coating, switch two printing surfaces freely. ### High Rebound Spring Steel Core Substrate Spring steel base features excellent flexible resilience, slight bend after print cooling to pop off finished parts without scraper tools. ### Wide Compatibility With Various Filaments Works well with PLA, PETG, ABS, TPU and most mainstream consumables, meets different adhesion demands of diverse materials. ### Water-wipe Convenient Daily Maintenance Surface residual filament stains can be wiped clean directly with damp cloth, simple upkeep prolongs service life. ### Firm Composite Layer Structure Three-layer composite of carbon fiber film+spring steel+PEI coating, tight lamination avoids coating peeling from repeated bending.
