Upgrade 310x310mm for Qidi Plus 4 Cold Build Plate PEI Sheet Double Sided Flexible Spring Steel Print Bed for Voron 300,Cr-10,CR-10S, CR-10S pro, CR-10V2, CR-10 V3 3D Printer

["【Dual-Sided Design – Two Printing Modes in One Plate】 This 310x3210mm build plate is specifically designed for .Green cold plate side: Supports low-temperature printing – PLA at just 30–50°C, PETG 65–75°C, ABS 80–100°C. Saves energy, prevents heat creep, and reduces warping – no glue needed. Black textured PEI side: Powder-coated frosted surface provides strong adhesion across a wider temperature range, compatible with PLA, PETG, ABS, TPU, Nylon, PC, ASA, and more (up to 300°C).","【Energy Saving · High Temp Resistant · Glue-Free – Both Sides Stronger】 One plate, two choices: Green Cold Plate Side – Energy Saving + Glue-Free.No glue or tape needed. Low bed temps deliver strong adhesion, prevent warping, and avoid heat creep. Saves up to 40% on bed heating energy vs traditional plates – lowers electricity costs. Black Textured PEI Side – High Temp Resistant + Glue-Free. Also glue-free. Frosted powder coating provides stronger first-layer grip, withstands up to 300°C. Works with low-temp and high-temp engineering filaments – no warping, no detachment.","【Advanced 7-Layer Durable Construction – Aerospace-Grade Spring Steel】 Built with an aerospace-grade spring steel core and a reinforced multi-layer structure (impact-resistant middle shields + nano-porous oleophobic coating), this plate offers outstanding scratch, rust, and corrosion resistance. It outperforms single-sided or glass plates in both flatness and durability.","【Effortless Model Release – No Scraping Required】 After printing, simply let the plate cool to room temperature, then gently bend it – the print pops off instantly without force or metal tools. The flexible spring steel core withstands repeated bending while returning perfectly flat. No scraper is ever needed, keeping both surfaces pristine.","【Easy Cleaning & Important Reminders】 Clean regularly with clean water and a soft cloth. Do NOT use alcohol, acetone, strong detergents, or any chemical reagents – they will damage both the cold coating and the textured PEI surface. Always re-level the bed when switching between sides. Before ordering, confirm your printer's build plate size is 310x310mm. Each plate undergoes strict quality inspection before shipment.
