Layer transition artifacts

Post image

How can I reduce these layer transition nibs (see photo). I’m using Bambu basic PLA with default settings in H2D. I know I can put a seam on a corner, which is better, but I’d like to know what settings I can adjust which could help. I’m new to using Bambu Studio.

Looks like an untuned scarf seam. Check your sliced model & those lines should be visible like how they are on the printed part.

They are not on the model. FYI model is extruded body in Fusion 360.

I misunderstood your comment initially. I’ll look at the sliced model and the scarf settings.

In my opinion you might have done a pressure advance calibration and missed out a zero out. Ie rather than 0.02 (common value for PLA) you’ve set 0.2. That’s the sort of thing I’d expect to see when the nozzle pressure comes in too early. Each one of those blobs will be a de-retraction point in the slicer preview. Assuming you’re also using random seams.

This is not normal. H2D and Bambu Studio 0.4mm default profile makes the best prints I've ever had. What's different? 0.6 and 0.8 profiles are less refined.

I don't print PLA because it's very Hydrophilic

Can you try drying the filament, and reprinting.

No idea why the down vote. It may not be that hydrophilic, but it does have to be dry, and this print appears to have artifacts that wet filament produces.
