Upgraded Prusa Core One Build Plate Smooth & Textured PEI Sheet 100% Imported Thicker PEI Film 254x241mm Flexible Spring Steel Bed for Prusa i3 MK3s

Upgraded Prusa Core One Build Plate Smooth & Textured PEI Sheet 100% Imported Thicker PEI Film 254x241mm Flexible Spring Steel Bed for Prusa i3 MK3s

【Dual-Side Premium Construction & Stable Performance】: Features two high-performance sides – a proprietary PEI powder coating (factory-proven for consistent quality and strong adhesion) and 100% European-imported PEI film. The imported film delivers superior adhesion and durability compared to economical domestic PO/PET films. Cold-rolled pure stainless steel core offers better rust resistance and structural strength than low-grade manganese steel alternatives. 【Dual-Side Advantages & Usage Guidance】: The PEI powder coating side withstands temperatures up to 300°C, works with diverse filaments (PLA, PETG, ABS, etc.), provides a frosted finish and easy maintenance. The imported PEI film side (120-150°C resistance) creates smooth, flat prints for refined results. Critical Tip: Apply glue on the film side when using PLA-SILK, PETG or TPU to reduce adhesion, prevent film damage during demolding and enable easy model removal. 【Key Usage & Maintenance Tips】: Peel off the transparent protective film on the PEI film side before first use. Ensure proper printer leveling and maintain a suitable nozzle-plate gap to avoid scratching the PEI coating. Adjust hot bed temperature per filament supplier guidelines for optimal adhesion. Demold only after natural cooling to room temperature to protect the PEI film. Clean with warm water, soap-based cleaner or alcohol when dirty or adhesion weakens to restore performance and extend service life. 【Model Compatibility & Normal Bubble Phenomenon】:This Sized at 254x241mm, it fits Prusa Core One MK2 MK52 MK3 MK3S MK4 MK3S+ MK2.5S and similar-sized 3D printers. (verify your printer model prior to purchase). Micro-bubbles on the film side are a normal physical reaction to 3M adhesive heating and do not impact printing performance. Opaque black films may also have such bubbles, which are simply concealed. Exercise discretion when purchasing if visible bubbles are a concern. 【Stable Quality & Reliable Performance】: Factory-tested construction ensures consistent performance for long-term use. The premium material selection and rigorous manufacturing process deliver a dependable 3D printing surface that meets diverse project needs, from hobbyist creations to professional prints. ✨ Dual-Side High-Performance Design: Proprietary PEI powder coating (300°C heat resistance, stable adhesion, frosted finish) and 100% European-imported PEI film (120-150°C resistance, ultra-smooth prints, superior durability). 🛡️ Premium Core Material: Cold-rolled pure stainless steel core for rust resistance, strong structural strength and bend resistance, outperforming low-grade manganese steel. 🧼 Easy Maintenance: Clean with warm water, soap or alcohol to restore adhesion and extend repeated use life. ⚠️ Usage Tip: Apply glue on the PEI film side for PLA-SILK, PETG or TPU; micro-bubbles are a normal thermal reaction of 3M adhesive, no impact on printing performance.
