Artifacts when using "fillet" and "scale"

[alya_gribovskaa]

Hi,

I am creating a multi-start thread for printing on a 3D printer using the “coil” tool and in the section of the model it is visible that artifacts (irregularities) appear after using the “fillet” and “scale” commands, but they are not visible in general on the part. I use “Fillet” to round off corners because I heard that it has a good effect on 3D printing.
Сould you please tell me, will the manifestation of these artifacts affect if the 3D model is printed on a printer? And how can I get rid of these irregularities?

Hi,

I assume it's just a ‘display error’.

change display detail control setting > adaptive to fixed:

Hi, thanks for your response. I applied this function, but nothing changed, I attached the photo below.

Maybe there are other possible solutions ?

Thank you, I have attached the file, I am waiting for an answer.

What you see are screen or 3D Viewport tesselation artifacts. This is a necessary evil of most 3D modeling software.

In order to be displayed on a computer screen, 3D geometry has to be broken down (tesselated) into triangular facets, which is what you are seeing.

The settings @g-andresen referenced help reduce the visual effects of that in most cases, but in this case some of it is still visible.

Your geometry representation in computer memory is fine.

Hi,

1. you can see that the fillets of the external thread (fillet 12) leads to a ‘change’ in the display.
2. this distortion is amplified by the scaling (scale 6).
I am not an expert on threads, but I think that the scaling (x;y) distorts the course of the thread.

Maybe @MRWakefield  can comment on this.

@g-andresen @TrippyLighting  thank you for the comprehensive answers, you helped me a lot.
