Hi Ad, can you please post the .3dm model file that the screenshots are taken from?

That would make it a lot easier to be able test possible tune ups.

The Resolution controls the density of the zbuffer pixel grid used to determine visibility, and increasing it to around say 60 or so should usually help with these issues.

Another thing you can try is make the overall object scale around 10 to 30 units across and not have things that are a lot smaller or larger in size than that.

If you are generating it on a perspective 3D view make sure the object is framed well inside the viewport and isn't only taking up a small portion of the viewport.

It's difficult to give advice without being able to test with the actual file though.
