Test print for Colorfabb LW PLA parameter optimization. I did not see a good way to optimize flow for Bambu printers. I made multiple profiles with different flow rates to optimize the settings for my P1S. 

I am unable to upload the .3mf with custom filament profiles so I can walk you through the approach.

1. Follow the link below “Bambu Labs Profiles”. These are custom profiles from ColorFabb for bambu printers.
2. Find and download “ColorFabb LW-PLA.3mf”.
3. Create 9 or so different parameters with different flow rates and temperatures. You can also adjust retraction settings but I would do an additional print to dial that in.
4. Apply the custom profiles to the 9 different cubes. I went with 230 - 250 C with flow rates varying from .35 - .55.
5. 240 C at .5 worked best for my printer but I still had stringing. I still need to dial in retraction.

The photo is from Varioshore TPU. I was unable to find the photo of LW PLA.

Bambu labs has a filament called PLA Aero. The approach should be very similar to dial in the material.
