Perfect Printing Parameters for ASA-Aero filament

I purchased a roll of official Bambu Lab ASA-Aero filament, but I found that the official printing parameters did not print well, and even after referring to the printing guide on the Bambu Lab wiki, printing still had issues

So I started a lot of attempts and found the perfect parameters for printing Bambu Lab ASA-Aero filament, which I will share here

Things to prepare before printing:

• Completely dried ASA-Aero filament

Dry at 65 degrees for at least 6 hours; the dryness of the filament is key to printing

• Bambu Lab smooth PEI print plate and bed glue

Unfortunately, a smooth print plate is essential. A smooth surface makes it easier to remove the model; if a textured PEI print plate is used, it will make the foaming filament difficult to remove and will leave residue on the print plate

Glue must be applied before each print. The glue does not increase the adhesion between the model and the hotbed but acts as an intermediate layer to make model removal easier

Preparing printing parameters

Now, let's prepare my printing parameters! You have two ways to use my printing parameters

The first and simplest way

Directly download my print profile, delete the self-contained model, drag your model into it, and choose to import model data only

Then you should see that the configuration on the left has changed to "Foaming Filament Printing," and the filament type is also in a modified state

Don't rush yet; start printing after reviewing the following precautions

The second way

If you want to try to understand the modifications I made or verify the parameters imported in the first step, you can refer to the figure below for a detailed comparison

Solid circles indicate important parameters; you must fill them according to my settings unless you understand their specific meaning

Dashed circles indicate adjustable parameters that can be modified as needed

• Filament Parameters

Flow rate: The default ratio is not enough; at least, that's what my tests showed. Increasing it to 0.6 is just right

Retraction: The default distance is too long, and foaming filament can easily clog the nozzle after prolonged retraction. 1mm might be slightly conservative; it can be slightly increased

Z-hop: Must be off, as it will cause very ugly Z-seams on the surface

• Printing Parameters 1

Align seam selection, or manually draw seams according to the model

Inner wall compensation must be enabled; foaming filament will make the model slightly larger, similar to matte filament

Print infill first to improve outer wall quality

Avoiding crossing outer walls can reduce stringing

The bottom shell thickness is to prevent the bottom layer from remaining on the print plate when removing the model

• Printing Parameters 2

Disable overhang speed reduction; overhangs might be worse after speed reduction

Supports require a larger Z distance; otherwise, the model will be damaged when removing supports

This concludes the printing parameter settings; there are a few more points to note

Points to note:

1. Plate arrangement

Be sure to enable print by object, otherwise, there will be a lot of stringing due to retraction + travel

2. Wall count

This depends on your model's quality requirements; generally, setting 1 wall is sufficient, but you can also increase it appropriately to improve surface quality in sunlight

Finally, after slicing, check the print preview. You should see the following details:

• Print by object
• No travel inside the model
• Z-seams are aligned with no spiral ascent

Start printing!

After you finish printing and removing the model, remember to reapply glue
