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.
The Bambu Lab Engineering Plate is designed for optimal adhesion during printing, but there may be cases where the results are not as expected. Here are some recommended steps to troubleshoot adhesion issues with the Bambu Lab Engineering Plate.
Periodically, we recommend cleaning the Bambu Lab Engineering Plate to ensure that the printing surface is clean of debris, old glue sticks, and fingerprints. The natural oils from your hands can transfer to the printing surface, impacting the sheet's adhesion properties
We recommend cleaning the printing surface with warm water and regular soap. You can use a basic sponge and dishwashing detergent, wash it with water, and dry it with a regular paper towel.
Most filament types come with a default preset in Bambu Studio. If you customize your profile, we recommend double-checking the temperatures set for the heatbed. Sometimes, you might need to adjust the temperature based on the type of filament used and its properties.
Typically, higher-temperature filaments are used on the engineering plate, and temperatures are set between 80°C and 100°C, depending on the material.
Part cooling is less important when printing with higher-temperature materials compared to regular filaments. Cooling settings should always be adjusted according to the specific filament being used.
For example, when printing ABS, a fan speed of approximately 30% to 40% is sufficient to expedite filament solidification without causing undue stress on the print that may lead to delaminations.
Another tip for ensuring optimal adhesion with the Engineering Plate is to initiate the part cooling fan only after completing the first three layers.
You can adjust slicer settings for the first layer to enhance adhesion. The slicer profiles in Bambu Studio come pre-configured with values that were performed best during testing. However, if issues arise, we recommend starting the print with a 0.5mm line width and a 0.25mm layer height for optimal results. These settings establish a solid foundation for the rest of the model and increase the chances of success.
