- Upgraded PackagingIncludes 1 textured PEI steel build plate and 2 bonus SK5 scraper blades (gift). Blades are handle-freeplease 3D print your own and use standard 0.2-inch screws if needed. Enjoy better adhesion and easier print removal.
- Key Benefits & Features Unlike smooth PEI sheets, our flexible build plate features a double-sided textured PEI surface that delivers exceptional adhesion and reduces warpingno glue or tape needed. Made from premium spring steel and coated with our proprietary dual-layer PEI, it withstands high temperatures up to 300C with zero deformation. Perfect for PLA, ABS, PETG, PC, and more. Plus, the reusable double-sided design means twice the printing surface, less waste, and more value for your money. Durable, reliable, and built to lastthis is the build plate your 3D printer deserves
- Usage Guide & Precautions: Upon receiving the steel plate, carefully peel off the protective film and clean the surface with alcohol to maintain cleanliness. When leveling, pay close attention to the nozzle-to-PEI distance (recommended 0.20.3mm) to prevent scratches. Precise control is ensured through real-time sensor feedback and dynamic compensation. Note: Any damage or contamination to the PEI surface will affect its lifespan and print quality.
- Easy Print Removal & Simple Cleaning The flexible spring steel build plate allows you to easily remove prints. After printing, simply let the platform cool naturally to room temperature for automatic release, or gently flex the plate to quickly remove the model without causing any damage. Clean the PEI surface with 75% alcohol or mild soapy water to remove residue. For stubborn stains, preheat the plate to 150C and gently scrub with a soft brush to ensure optimal adhesion for every print.

Size: 330x330mm
Style: Gold PEI Sheet
This Upgraded 330x330mm PEI Build Plate is a champion of durability. It completely reverses the disappointing trend of its flimsy competitors—this sheet is sturdy, well-built, and impressively scratch-resistant. You can work with confidence, knowing a simple plastic scraper isn't going to mar the surface. More importantly, it performs flawlessly where it counts: holding onto anything you print with excellent adhesion. This is a reliable, high-quality component that truly deserves a spot in your 3D printing setup. It does such a great job that it immediately earned a spot on my "must-buy backups" list for when another spare is needed!

Works great... Easy to pop off prints. Holds up rather well for the massive amount of prints I do.

Purchased for a qidi plus 4. It’s thinner than stock and the texture is not as raised, which is a good thing. This performed better than the stock.

Sticks well to PETG filament, but the 310mm size was a bit too large for my 300mm Voron.

Style: Gold PEI Sheet
Magnet sheet worked fine to fit a CR-10 clone. Grip to the steel sheet feels good, unsure of the max temp the magnet will lose magnetism. Seems to be fine with PLA and PETG temps. The only complaint is the blades that come as extra. They are way too sharp and you will need to dull them considerably to use them on plastic. I’m going to keep them but they’ll never touch the PEI bed they came with. Not quite sure who thought putting razor blades to be used as a scraper for plastic is but they more than likely were trying to get you to ruin your own build surface. Dawn dish soap and 320 grit steel wool is all you need to clean it and keep it grippy.

Neptune Max 4. Works great on my Elegoo printer. I use Dawk dish soap and warm water to clean up. I let things cool down, prints come right off.

All right...that's not true. But it is one of those rare purchases that I have made in my life that I look back on and think to myself, "I am sooo glad I bought this." I had bought another PEI plate from another company that fell apart fairly quickly. And I have never had prints stick fully and easily to my build plate, ever. I print large objects, and the corners almost always pull up. Even when spraying noxious chemicals on it. Now, I don't ever have to spray, the prints fully stick, and when it gets cool enough, they pop off easily. What more could you ask for? I found that for my printer, I had to increase the bed temp 10-20 degrees for it to work properly.

Great replacement, everything sticks phenomenally, yet once cool pops right off the plate. Very happy with this!
