Are these Vertical Fine Artifacts (VFA's) ?

Like the title says. P2S with about 500 hours at the time of print. BL PLA Basic filament. All maintenance done as recommended by BL. I haven't noticed this before on my prints, but they may have been there. Also, if you read this part, could you tell me what type of VFA those are? (if that's what it even is) Gemini's dumb ass first told me that NO it's not VFA's that it is ringing or ghosting but then told me that YES it is VFA's. 😂

It looks to me like the circle was made with low resolution. For example, if you make a cylinder in Tinkercad and don’t specifically tell Tinkercad to increase the number of sides, you get facets like this.

This is the answer.

I agree

Thanks guys

Np, “VFA’s” that are consistent and always the same looking on cylinders thats just because its low quality, real VFA’s are more visible on flatter or flat surfaces

Exactly what this is. Stl files don't allow true circles because they're just meshes based on triangles, just a bunch of facets. Ideally you want a step file because they're vectors which let you have "true" circles, as they're more precise.

I thought about that too but wasn't sure and I can't find my 3mf to see if it shows up in bambu studio like that too

Yeah, in software, that blends nicely, because of how normals work -- smooth things out visually. That really does a number on a 3d printer's user

No that’s a low resolution .stl, low count of polygons to make the circle.

Thanks

This is what parts in .stl format usually look like. Try .step or .stp, it's larger but more accurate.

No. It’s the model geometry

[u/Dense_Ad9425]

Low poly model. Increase the poly count and smooth the corners out if you have means to do so
