About this item

  • 1. 【Premium Build: Spring Steel + Upgraded PEI + Imported Film】： The spring steel core offers exceptional flatness and durability. The 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. The 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 & Returns】：254x241mm. Compatible with Prusa Core One,Prusa I3 MK3 MK3S MK4. We offer 30‑day free returns. Contact us within 24 hours for any issues.

FAQ

What types of products does Stemora offer?


Stemora offers supplies for science experiments, microscopy, biology learning, measurement, laboratory organization, electronics, robotics, coding education, 3D printing, maker projects, and classroom activities. Available products and specifications may change over time.

Are Stemora products suitable for children?


Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.

Is adult supervision required?


Adult supervision is recommended for children and students, especially when using electrical components, sharp tools, heated equipment, glassware, small parts, or experiment materials. Customers are responsible for following all product instructions and safety precautions.

Can these products be used at home and in classrooms?


Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.

How can I check what is included with a product?


Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.

How do I know whether an electronic or robotics part is compatible?


Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.

When will I receive tracking information?


Tracking information is generally provided within 3–5 business days after an order is confirmed. In some cases, processing may take approximately 7–8 business days. Delivery may require an additional 4–5 business days after tracking becomes available, depending on the carrier and destination.

Why did my order arrive in separate packages?


Products in the same order may be shipped from different fulfillment locations. As a result, items may arrive separately and have different tracking numbers. You will not be charged additional shipping fees solely because an order is divided into multiple packages.

Can I change or cancel my order?


Contact us as soon as possible at vaioamaonaoak@gmail.com. We will try to assist, but changes or cancellations cannot be guaranteed once an order has entered processing or has been shipped.

What should I do if an item arrives damaged, defective, or incorrect?


Contact us promptly at vaioamaonaoak@gmail.com with your order number, a description of the issue, and clear photographs of the item, packaging, and shipping label. Please retain the product and original packaging while we review your request. Eligibility and available resolutions are subject to our Return & Refund Policy.
