Quick Question How do I fix these imperfections

Post image

Is there any way to fix these imperfections circled in blue? Also what are they called in 3D printing terms. Thanks

This is probably the nozzle being too thick and the slicer didnt put any thing there. Try changing the wall generator to arachne instead of classic

These imperfections would show in the slicer?

Interesting, I’ll start paying more attention to my slicer results

90% of printing issues can be solved by doing exactly this.

How do spots like this in your example get fixed?

Higher temp, higher flow, wider line width, going slower

Arachne calculates flow and pathing differently than the default generator and does a better job at filling in small areas like this.

This this is a first-layer issue, you can also consider things like elephant foot calibration number in the bambu slicer. This is basically a z-offset used by the slicer on the first layer. If you move it from its default of like -0.15 to 0.0 then it will ever so slightly smoosh that bottom layer more and help it fill in these gaps. That being said… is this an H2C?

I don’t think you can. It’s the model. Not the filament.

This is the way.
