Buying from AliExpress
AliExpress is a legitimate marketplace that is worth using for cheap, low-risk things like cables, tools, cleaning supplies and small home items, as long as you can wait and you buy from well-rated sellers. Skip it for anything safety-critical, brand-name or urgent. Check the seller's feedback score, the delivery estimate and the import-charge line at checkout before you pay.
- Shipping
- AliExpress's 2024 US guarantee listed Choice orders at 5 to 12 days and standard orders at 8 to 14 days, but real-world standard shipping from China often runs longer. Items marked Ship from United States come from local stock. Free shipping on Choice orders depends on a minimum order shown at checkout.
- Returns

- Warranty
- AliExpress does not publish a marketplace-wide product warranty. Coverage depends on the individual seller, and Buyer Protection covers non-delivery, damage and not-as-described claims instead.
- Payment
- US shoppers can pay by Visa, Mastercard, American Express or Discover, PayPal, Apple Pay and Google Pay. Instalment options such as Klarna and PayPal Pay Later appear on some orders, and availability varies.
- International
- AliExpress sells to shoppers worldwide. For US orders, import duties on low-value parcels have applied since the duty-free exemption ended in 2025, and state sales tax is added at checkout.

Frequently asked questions
Which size should I choose?
Measure your printer's heated bed in mm and match it. Ender 3-class printers often use 235 mm, while the title lists other sizes for different models.
Does it work with my printer?
The title mentions Ender 3, CR10, P1P and SW-X1, but compatibility depends on bed shape and any magnetic base. Check your printer's bed size before ordering.
How do I get prints off?
Let the bed cool, lift the plate off its magnetic base and flex it gently. Textured PEI usually releases the print as the sheet bends.
How long does shipping take to the US?
A flat steel sheet can bend in a thin envelope, so look at buyer photos for how it was packed. Delivery is generally one to three weeks, quicker through Choice or Ship from United States. Tracking is included, Buyer Protection covers a bent or missing plate, and import charges may appear at checkout.
