Upgraded Thicker SPARKX i7 PEI Build Plate & Cool Plate,301x267mm Double Sided Textured Low-temperature and Smooth PEI Sheet Flexible Removable Spring Steel Platform for Creality SPARKX i7 3D Printer.

["1. Premium Build: 0.5mm Spring Steel + Upgraded PEI + Imported Film The 0.5mm spring steel core is thicker than most for extra flatness and durability. Green side features an upgraded PEI powder formula that provides stronger adhesion and an ultra‑fine matte finish – much smoother than ordinary PEI spray coatings. Black side uses 100% imported PEI film for a bubble‑free, perfectly flat, smooth glossy finish.","2. Dual‑Sided for Different Printing Scenarios Green cold plate supports low‑temp printing: PLA at just 30‑50°C, PETG 50‑70°C, ABS 70‑90°C – saving energy and reducing warping. Black PEI film side gives you a smooth glossy bottom: PLA 55‑70°C and quality PETG ≤70°C (do not exceed 70°C). Neither side works with TPU, PC, nylon, or high‑temp engineering filaments.","3. Cold Plate That Delivers: Ultra‑Smooth, Strong Grip & Energy Savings Prints stick like a magnet even at low temperatures (PLA from 30°C) – no glue, no tape, no warping. The surface is incredibly smooth with no “orange peel” texture, so your first layer looks clean, flat, and professional. Cuts bed heating energy by up to 40% compared to ordinary PEI plates. For complex PETG on the black PEI side, add a brim/raft, use glue stick if needed, and slow first layer speed to 10‑15 mm/s. Never exceed 70°C bed temp on that side.","4. Easy Release, Cleaning & Nozzle Warning – How to Use Quick steps: Peel off protective film (black side only). Place plate on your heated bed. Level bed so the nozzle is one A4 paper thickness away. Print. After printing, let cool, then bend the plate – the print pops off. No scraping. Clean with mild dish soap and a soft cloth. Never use alcohol, acetone, or strong acids/alkalis – they will damage the coating or film. Avoid metal tools on the green side. Warning: A nozzle at 190‑220°C that touches the plate will cause irreversible heat damage (not covered by warranty).","5. Size, Compatibility, Magnetic Sheet & Returns Size: 301x267mm.
