=== Build Plates ===
The Bambu printers can use different build plates for different filament types. 

When people handle the build plate, their hands will deposit oils and dirt that can affect the build plate. It's therefore a good idea to rinse the plate with soap and water periodically (every 3-4 prints) to remove oil and dirt.

Note that some build plates require a glue stick for proper adhesion; if you use a glue stick, please clean the plate with soap and water when you are done. Do not use isopropyl alcohol or solvents on the build plates.

==== Textured PEI Plate ====
The textured PEI plate is used for PLA, ABS, and PETG. It leaves a textured surface on the bottom of prints. Typically you will not need to use a glue stick, however if you're printing with PETG it can help protect the bed.

==== Engineering/Cool Plate ====
The engineering/cool plate is a double-sided plate. The cool side is designed specifically for PLA, though you can also use it for PETG. The engineering side is used for exotic engineering materials like ABS, TPU, PA, and Polycarbonate. Glue is strongly recommended for both the engineering side and the cool side.
