Bambu Lab’s recent release of ASA filament has encountered adhesion challenges, particularly with the black dual-textured PEI build plate on enclosed P1P/P1S/P1PS printers. Initial profiles suggested the textured bed would work without glue, but practical experience has proven otherwise. Large prints with brims, using the stock ASA profile, often result in the brim becoming almost inseparable from the plate, potentially causing damage.
The root cause appears to be insufficient adhesion between the ASA filament and the textured PEI surface. Without a proper bonding agent, prints are prone to warping, delamination, and failure, especially when the part cooling fan activates for overhangs and bridges. This issue seems specific to the enclosed P1 series and doesn’t affect the X series to the same extent. Bambu Lab’s filament profile wiki and sales pages haven’t accurately reflected this requirement for glue with ASA on textured PEI plates.
The Glue Stick Solution: A Confirmed Fix
While liquid glue can exacerbate the problem by bonding too strongly, glue stick has emerged as a reliable solution. Bambu Lab customer service has confirmed successful prints using glue stick with the same ASA profile. A thin layer of glue stick applied to the textured PEI plate provides sufficient adhesion to prevent warping and delamination without causing excessive bonding that damages the plate during brim removal.
Initial attempts to resolve the issue by modifying the stock ASA profile, such as disabling the “Fan Always On” feature and lowering fan speeds, proved insufficient. Even with these adjustments, prints would still delaminate during bridging. This highlights the critical role of proper bed adhesion for successful ASA printing on textured PEI surfaces. The need for manual profile adjustments for a manufacturer’s own filament and printer is a significant drawback.
Conclusion: Ensuring Successful ASA Prints
For reliable ASA printing on Bambu Lab’s textured PEI plates, using a glue stick is crucial. This ensures sufficient adhesion without the risk of damaging the build plate. While Bambu Lab is working to resolve the documentation discrepancies and potentially refine its ASA profile, using a glue stick offers a readily available and effective solution. This ensures a positive user experience and avoids the frustration of failed prints and potential build plate damage. Remember, if it’s liquid, it can create a bond too strong for easy removal. A solid glue stick provides the perfect balance for successful ASA printing.
