【Special Design】: Excellent design——In a spring steel plate using 2 different materials, one side of smooth film can produce mirror printing effect, the other side of textured spraying, produce matte printing effect, Compared with the same materials design, it is more cost-effective. 【Proven Solution】:No glue, No tap, when hotbed temperature reaches 60℃ ,materials such as PLA，80℃ PETG，and 130℃ ABS will stick well, and after printing, when spring steel PEI build plate cools to room temperature, it's easy to remove the printed matter from the platform by bending slightly. Through hundreds of experimental tests, repeated use is still new.Note:The adaptation temperature of different materials is different. Please adjust it reasonably. 【Good Quality】: We use 100% imported PEI raw materials, which are thicker and more used, Easily handle temperatures up to 130°C and perfect for PLA, PEEK, ABS. The process is upgraded so it does not affect any use of bubbles. PEI is very expensive compared to PET/PEO, but its good performance, especially high temperature resistance and stability are still ahead. You get what you pay for, I hope you can choose more suitable products according to your own printing materials. 【Practical Features】:Size:300 x250mm/11.8x9.8 inch is suitable for QIDI X-MAX X-CF Pro and the same size other 3D printers. Clean the PEI surface with 75% alcohol or mild soap water to remove residue. For stubborn stains, preheat the plate to 150°C and gently scrub with a soft brush.The design allows for easy assembly and disassembly. Regular maintenance includes checking the spring tension (maintain 5N force) and cleaning the platform every 50 hours of use. 【【Notice】: Some specialty filaments like PLA SILK+ require very low bed temperatures (as low as 0-30°C) for safe removal. Using a higher temperature can cause strong adhesion and may damage the smooth PEI sheet. For optimal performance and to avoid such issues, always adhere to the material supplier's specific temperature guidelines.There are 1 piece Smooth/Textured build plate inside. 300x250mm/11.8x9.8inch Textured And Smooth Double-Sided PEI Sheet Build Plate Flexible Removable Spring Steel Sheet Compatible with SV01 SV02 QiD X-Max X-CF Pro 3D Printers
