Hi everyone,
I’m running into a frustrating issue on my Bambu Lab A1 and I’m hoping someone might have some fresh ideas, as I’ve hit a bit of a wall.
The Problem: When printing in “Spiral Vase” mode with Bambu’s own PLA Matte filament, a small blob of material slowly builds up on the side of the nozzle. After printing for a while, this blob inevitably gets deposited onto the side of the print, ruining the clean single-wall surface. The rest of the print quality is perfect.
My Setup:
- Printer: Bambu Lab A1
- Filament: Bambu Lab PLA Matte
- Slicer: Bambu Studio, using the “Spiral Vase” option
What I’ve Already Tried:
I feel like I’ve adjusted all the usual culprits, but the problem persists. Here’s what I’ve done:
- Lowering Temperature: The default profile is 220°C. I’ve tried printing at 215°C and 210°C. This seems to reduce the speed at which the blob forms, but doesn’t eliminate it.
- Adjusting Flow Ratio: I know the default for this filament is already 0.98. I have tried manually setting it lower, down to 0.96 and even 0.95. Again, maybe a slight improvement, but the blob still eventually forms and detaches.
- Reducing Volumetric Flow: I’ve tried lowering the “Max Volumetric Speed” in the filament settings, thinking it might be a pressure issue, but this had no noticeable effect on the problem.
- Cleaning: The nozzle is cleaned externally before every print, so the surface is clean.
- Speed: I have tried lowering the outer wall speed, with minimal success.
I’m starting to run out of ideas. It seems like there’s some micro-oozing that’s collecting on the nozzle no matter what.
Has anyone else experienced this specifically with PLA Matte in vase mode?
Any help or suggestions would be greatly appreciated!
Thanks!!!
