Bambu Cool Plate consists of two parts: the Cool Plate sheet and the Engineering Plate. You can print on both sides of the plate.
The cool plate sheet, made of PC, has a smooth surface. It's attached to the engineering plate using 3M high heat-resistant double-sided tape. This plate is specifically designed for printing PLA filament. However, if you try to print with materials like PETG or ABS, you might encounter issues like bubbling and sticking. It's important to remember that when printing PLA on the Cool Plate, you need to use a Bambu glue stick or liquid glue for proper adhesion.
Bambu High Temperature Plate consists of two parts: the High Temperature plate sheet and the Engineering Plate. You can print on both sides of the plate.
The high-temperature sheet is made of PEI, featuring a smooth surface and a fine matte texture. It's attached to the engineering plate using 3M high-heat-resistant double-sided tape. Unlike the PC sheet used in the Cool Plate, PEI material offers better heat resistance and is less likely to deform under high temperatures. This makes it more compatible with various filaments.
Except for the PLA filament, When printing with other filaments, it's highly recommended to use adhesive (Bambu glue stick or liquid glue is recommended) to ensure proper adhesion between the filaments and the build plate. This is crucial to prevent the risk of cracking the high-temperature sheet.
Engineering Plate is made by applying a special thermosetting coating on spring steel. This makes the printing plate stronger than PC and PEI sheets. It's ideal for printing engineering materials. However, one drawback is that you need to be strict about using adhesive (Bambu glue stick or liquid glue is recommended). If you don't apply adhesive properly, the plate might not stick well, leading to printing issues.
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
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.
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 is not happen.
Our Cool Plate and the High Temperature Plate are made based on dual-sided Engineering Plates. One side is attached with a cool plate sheet and a High Temperature sheet, which creates a Cool Plate and a High Temperature Plate respectively. You can use either the Cool Plate or the High Temperature Plate, each paired with an Engineering Plate on the opposite side. The sheets are replaceable, giving you the flexibility to customize them according to your specific needs. (Learn more about replacing sheet: How to replace the Bambu Lab Plate sheet).
Note:
When printing on a Cool Plate, High Temperature Plate, or Engineering Plate, make sure to apply a thin layer of our official glue stick or liquid glue to the plate before starting the print. (Third-party glues are strongly discouraged and may cause damage to the plate). 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).
Alternatively, we provide Textured PEI Plates that allow you to print without the need for a glue stick.
