I don't have pix, as I toss the not-so-good prints, but the issues appear in a couple of areas.

- Until I put a small flat on it, the "peak" of the flattest side had an area about 6mm that was all rough and lumpy. It's where there was a couple of hundred triangles all coming to one point. there's a name for this issue, although I can't recall it.

- Sometimes I get 10mm long narrow indented valleys that run from the juncture of the round barrel at the bottom and the "egg" toward the center of the flattest curve.

- I've also seen a 4mm wide patch of rough surface running up to the lower center of the flattest curve.

- Other times there are fairly obvious oval rings around the center of the flattest curve.

Bottom line is that MOI feeding a slicer seems to do a mediocre job when you crank up the resolution on the .stl. I've seen the same issue using Cura and Kisslicer.

Do you mean you saw these results using the settings I just posted a minute ago?

If not then the bottom line is that you just needed to just adjust a few settings to generate a denser mesh.

It's hard for me to really follow the specifics of this - if you want more help getting better results in MoI it would be a lot clearer if you could post an image with these particular areas circled.

Just in general with a simple look (and in the screenshots I posted above) I was not able to see any of the problems that you are mentioning so that makes it a bit difficult to give you very good feedback about what you should do to improve it. My best guess though is that you want to use "Divide larger than" with a setting of "All" to force more even divisions throughout your mesh.

I would say it will be a combination of settings.

So it appears he is having issues where "poles" are created for the stl mesh.

Poles are not necessarily bad and don't specifically make something "not smooth", but they can create effects when combined with the other settings that have to do with generating a path for the printer.

Although you have a high resolution printer, there will be settings that determine the print resolution. Various step/size settings for the print. Nozzle stuff etc.....

These combined with the sizes/counts of the polygons will affect the end result.

Ricks problem is referring to the finished product from the 3d printer the mesh from MoI is fine it's when the mesh is put through the 3d printing software which slices the model to create paths for the printer according to what resolution is set for the specific printer so it's the resulting slices that are the problem.
Like Dinos I've had no such issue with my 3d printer exporting stl files from MoI.

Yeah when your mesh is not dense enough it's possible for some aspects of the mesh structure to come through in the final print...

In order to avoid that you need to adjust some settings to produce a dense enough mesh to avoid seeing individual polygons.

The main settings to use for that are set an Angle fairly low, but then also use the "Divide larger than" setting to force a more uniform dicing of the mesh. From what I can tell from what he wrote, Rick has not used "Divide larger than" for the output he had difficulty with. It's hard to say for sure though without more specific information from him.
