A PEI (polyetherimide) build plate is a type of build plate that is commonly used in 3D printing. PEI is a type of plastic that is known for its high thermal stability, chemical resistance, and low coefficient of friction. These properties make it an ideal material for use as a build plate, as it can withstand the high temperatures required for 3D printing, and also provides a smooth and stable surface for the printed objects to adhere to.
One of the main advantages of using a PEI build plate is that it allows for easy and consistent adhesion of the printed objects. PEI has a low coefficient of friction, which means that it allows the filament to flow smoothly and freely, which in turn results in more consistent and accurate prints.
Another advantage of PEI build plates is that they are easy to maintain and clean. They are not sticky to the touch, and after printing, the object can be easily removed with a spatula or scraper, or with a light tap. Additionally, PEI is resistant to chemicals, so it can be cleaned using alcohol, acetone or other similar solvents.
PEI build plates are also very versatile, they can be used with a wide range of filament types, including ABS, PLA, and PETG, among others. They also work well with both heated and unheated build plates.
It's important to note that PEI is not a common material to find in pre-built 3D printers, and it's more likely to find it as an adhesive sheet that can be applied to other types of build plate.

In conclusion, PEI build plates are a great choice for 3D printing due to their high thermal stability, low coefficient of friction, and chemical resistance. They offer an easy-to-use and consistent surface for adhesion, and are easy to maintain and clean, making them an ideal choice for both hobbyists and professionals. However, it's important to keep in mind their limitations and its not the perfect material for every situation.
