¶ Textured PEI Plate
Textured PEI Plate is made by coating a stainless steel sheet with a layer of PEI powder, creating a textured surface on both sides. What sets it apart is its special rough texture, which is transferred to the bottom surface of your prints. This plate works well with a variety of materials and often provides excellent adhesion without the need for adhesives, making it user-friendly. Additionally, the PEI coating on the plates is durable and has a long lifespan.
The latest firmware brings significant improvements to the Bambu Textured PEI Plate calibration using the Micro Lidar, and it is now fully compatible with the automatic calibration process
¶ Smooth PEI Plate
The Smooth PEI Plate is obtained by adhering a carefully selected PEI sheet to a spring steel using a highly heat-resistant 3M adhesive. The Smooth PEI Plate provides a flat surface for printed objects and is suitable for scenarios that require a level bottom surface.
The PEI sheet on the surface of the Smooth PEI Plate allows for printing with various filaments.
Only PLA filament does not require glue, while printing with other filaments requires the use of gluing to prevent the PEI sheet from tearing.
The thicker 0.5 mm spring steel helps reduce the risk of warping in the printing plate.
¶ Wipe zone on the build plate
Before printing, there may be some filament residue remaining on the nozzle, and if not cleaned, it can cause surface defects on the printed object. Therefore, the nozzle is first wiped on a nozzle wiper before printing starts and then repeatedly wiped in a specific area on the build plate (wipe zone). This helps to clean the filament residue on the nozzle and stabilize the chamber pressure inside the nozzle. This prevents surface defects on the printed object due to filament residue on the nozzle.
For the X1C, P1S/P1P, and A1 printers, as the nozzle comes into direct contact with the build plate, there may be some "wear" observed in the wiping zone (as shown in the image below). However, this phenomenon does not affect the functionality of the nozzle or the build plate.
For the A1 mini printer, there is a wipe zone on the heatbed to clean the nozzle. Therefore, the phenomenon of "wear" on the build plate will not happen.
¶ Summary
For the correct gluing procedure, please check How to Use Bambu Lab Glue. Ensure that the print adheres properly to the plate without causing damage to the surface by sticking too tightly. Otherwise, the sheet may bubble or crack. Also, third-party glues are strongly discouraged and may damage the plate.
Alternatively, we provide textured PEI Plates that allow you to print without the need for a glue stick.
