Why is this model 'Capping' upon slicing?

[kmanstudios 1,120]

The object passes all the 3DS MAX STL checks. Looks good. Is fully enclosed. Why would an open model like this cap across these surfaces?

Is "Union Overlapping Volumes" in "Mesh Fixes" selected?

If so, unselect it should help.

And just a general comment. Don't be too disappointed if that print doesn't come out perfect. That's a very difficult print.

@Berndjm-----I had to take off all the mesh fixes to get it to work. But, if you're setting it up in right in your 3D Package, no need for them, eh?

@IRobertI-----I'm just testing out things right now. Since I can't get the printer until December, I'm setting up files to see what it does when it gets here. And, also apparently learning about the software too! LOL But I have a few projects that I want to try and see just how far I can push it.

Besides, it's a Fractal.....it supposed to look 'off' a bit anyway

Thanks for the suggestion about the mesh fixes.
