The Bambu Lab High-Temperature Plate's surface is comprised of a customized PEI material that is compatible with almost all popular filaments and provides a very smooth print surface. Over time, customers may encounter problems with insufficient adhesion of the build plate, so here are a few recommended steps for troubleshooting adhesion issues with the Bambu Lab High-Temperature Plate.
From time to time, we recommend cleaning the Bambu Lab High-Temperature Plate to ensure that the printing surface is clean from any debris, old glue stick, or fingerprints. Natural oils that are present on your hands can find their way onto the printing surface, which will impact the sheet's adhesion properties.
We recommend cleaning the printing surface with warm water and regular soap. You can use a simple sponge and dish-washing soap, rinse it with water, and dry it with a standard paper towel.
Using isopropyl alcohol to clean the High-Temperature Plate should work as well, but it might be more difficult to remove old glue stick residue.
The force between the filament and the build plate is highly affected by the heatbed temperature; the higher the heatbed temperature, the stronger the adhesion. If you suspect the adhesion force is insufficient, you can raise the bed temperature slightly to increase adhesion.
Note: For PLA and PETG materials, exceedingly high temperatures might create clogging and elephant foot problems.
The force between the print and the build plate is approximately proportional to the contact area between the two. When printing small objects, a brim increases the pressure between the image and the build plate to prevent the print from warping or falling off. Some thin and tall things are more likely to be scraped by the nozzle when printing at high speed. Proper support is recommended when printing these objects to optimize the overall force structure and thus reduce the risk of a print warping or falling off.
While most filament types have a default preset in the Bambu Studio, if you customize your profile, then we recommend double-checking the temperatures set for the heatbed. Sometimes, you might also need to adjust the temperature based on the type of filament used and its proprieties.
For increased adhesion, you can also adjust the slicer settings for the first layer. The slicer profiles included in Bambu Studio are pre-configured with values that worked best during testing. However, if you have issues, we recommend starting the print with a 0.5mm line width and a 0.25mm layer height for best results. These settings will provide a good base for the rest of the model and increase the chance of success.
If you still encounter adhesion issues after following the steps described in this article, feel free to create a ticket, and our support team will help.
Please make sure to use a thin layer of glue stick to ensure that the models do not stick too hard to the print surface.
Beside that, please allow the plate to cool down before removing the prints.
Following these guidelines will ensure a long lifetime of the plate and will ensure that the new replacement plates will be much less likely to get bubbles under the sheet.
The problem can only be fixed by replacing the sheet. How to replace the Bambu Lab Plate sheet | Bambu Lab Wiki
Please try to remove the bubbles with the following technique.
1. Turn the sheet over the sticker side down to the heatbed.
2. Heat the bed to 100 ℃.
3. Once the bed has reached temp, please turn off the heat and let it cool.
4. Once cool to the touch, check the sticker side to see if the air bubbles are still there.
If the above steps still cannot remove the bubbles, then the only solution is to replace the sheet. How to replace the Bambu Lab Plate sheet | Bambu Lab Wiki
Some high-temperature plates are supplied with a plastic protective film. If you receive a high-temperature plate that has a plastic protection film on the surface, please remove it before using the build plate.
