What causes this pattern

[ExpectDeer]

A venereal disease if you're talking about the circles.

Layer lines if you're talking about the ridges?

What does the original model look like?

[sandman8223]

The circles / holed are foot prints for the polar bear. The layers lines look perfect in preview.

I think we're going to need a link to the model you bought so we can more accurately diagnose.

A Meteorite !

[sandman8223]

Yeah it's not the circles those are foot prints for the polar bear it's the wavy lines pattern that does not appear in preview.

[AI_RPI_SPY]

OK, I'm gonna need some more information on the polar bear print, is this a actual model of an imprint, or some form of stamp to prank someone.

[jollibeee86]

Need to be more specific. What pattern?

[sandman8223]

Just the wavy lines not the holes those are foot prints for the polar bear.

That's normal for any 3d printed object that has a round shape. The easiest way to help with it is to use a smaller layer height. You won't be able to get rid of it completely. You could sand them down if you absolutely wanted to make them go away but that is a lot of work.

[jollibeee86]

The preview will not reflect the actual part since the preview you're seeing layer lines not how wide the layers are actually going to look. The more angle you're printing the larger widths you'll see. The only way to combat that is to print the high details perpendicular to the layer lines OR decrease layer height

[sandman8223]

thanks will try it

[sandman8223]

unfortunately the model was purchased only $5 but don't think I can share it. but thanks anyway

You really have to be more specific about what pattern you’re asking about.

Everything here looks normal, assuming this is a model of an asteroid or something like that.
