Buildplate for Bambu Lab 3D printers

Build plates in FDM 3D printers may need replacement due to wear and tear caused by repeated use, leading to decreased adhesion and print quality. Over time, the surface may become scratched or damaged, impacting print bed leveling and adherence of filament. These original replacement buildplates for the Bambu Lab 3D printers are available in the following variants:

The features of each type of buildplate will be discussed in detail below.

Textured PEI plate

This textured PEI plate for the Bambu Lab X1/P1/A1 3D printers is made of a sheet of magnetic stainless steel (0.5 mm) coated with PEI powder coating (0.075 mm). The PEI coating gives the builplate the capability to withstand repeated heating and cooling cycles without property loss. Furthermore, it creates a unique rugged surface finish on the bottom of the printed part. The magnetic steel plate significantly reduces the risk of the first layer detaching due to deformation.

This design and combination of materials provides strong adhesion of first layer to the buildplate and ensures effortless print removal by simply bending the buildplate gently. This buildplate is very durable and comaptible with various filaments such as PLA (also with carbon and glass fibers), ABS, PET/-G (with fibers), TPU, ASA, PVA, PC (with fibers) and PA (with fibers). No adhesion product is necessary to ensure excellent adhesion (with the exception of TPU, PC and PA). If an adhesion product is used, it should be the official Bambu Lab glue.

High temperature plate

The Bambu Lab high temperature buildplate for the X1/P1/A1 3D printers ensures superior first layer adhesion and easy part removal. The surface of this buildplate is smooth and matte, which results in a smooth texture on the bottom of the print. This high temperature buildplate has a unique dual-sided design (both sides can be printed on) where one side is the Bambu Lab engineering plate and the other side has an additional high-temperature sheet.

The Bambu Lab engineering plate is crafted through the application of a unique thermosetting coating onto spring steel, imparting greater strength compared to PC and PEI sheets. This renders it well-suited for the printing of engineering materials. The high temperature sheet is made of PEI, which results in improved heat resistance and a reduced risk of deformation at high printing temperatures.

This HT buildplate is compatible with most 3D printing filaments such as PLA (also with carbon and glass fibers), ABS, PET/-G (with fibers), TPU, ASA, PVA, PC (with fibers) and PA (with fibers). The use of the official Bambu Lab glue is recommended with all those materials except for PLA.

Dual-sided textured PEI plate

This dual-sided textured PEI plate has the same properties as the textured PEI plate for the X1/P1/A1 3D printers. Apart from offering a different build surface compatible only with the A1 Mini 3D printer (180 x 180 mm), this dual-sided textured PEI plate provides users with the option to have a spare or backup printing surface readily available.

This can be particularly beneficial in scenarios where one side of the plate becomes worn or damaged over time. Instead of replacing the entire plate, users can simply flip it and continue printing on the unused side, extending the overall lifespan and usability of the PEI plate. Additionally, it allows users to experiment with different bed adhesion properties or textures without needing a separate plate, offering a convenient and flexible printing experience. 

Temperature recommendations

It must be remembered that using third-party adhesives (other than the official Bambu Lab glue) may damage the buildplates.

Maintenance and warranty

The Bambu Lab build plates are classified as consumable components and may experience degradation with time. The warranty excludes cosmetic issues such as scratches, dents, or cracks resulting from improper use and maintenance. Only build plates found to be defective upon arrival are eligible for warranty coverage. For maintenance tips please see the Usage Tips section.
