What pei sheet actually is
PEI on spring steel is the default happy path for many FDM owners: stick when hot, flex-release when cool. Texture vs smooth PEI changes bottom finish.
Keep it clean with the right wash; hard tools scratch coatings. Some materials still want adhesive helpers.

- Spec sheets and ads use pei sheet as a premium or safety badge
- Buyers compare mid-range vs flagship partly on pei sheet
- Support articles and unboxings repeat the jargon without decoding it
Buyer takeaway: If your printer supports it, a good PEI sheet is one of the best beginner upgrades.
