Hi there, my first question for this forum! I am flowing a pattern onto a revolved curve (then Boolean unioning). Works beautifully, but when trying to 3d print the confirmed solid in vase mode, there are tiny gaps between the pattern and the curved surface. I looked at this discussion: http://moi3d.com/forum/messages.php?webtag=MOI&msg=4885.3
and have tried sinking the pattern further into the base plane, but still no luck. Haven't used flow before, so any help appreciated!

Hi Lynn, can you please post the .3dm model file of your vase? If you want to keep it private you can e-mail it to me at moi@moi3d.com .

Thanks, - Michael

Thanks Michael, I've attached the file. Cheers, Lynno

Hi Lynno, your model seems to be fine, I'm not seeing any problems with it.

Can you show what the problem with the gaps in the printed result look like?

- Michael

Thanks Michael, I haven't printed it yet as Simplify 3D is telling me there are non-manifold edges. It may be an STL file issue. I will print it and let you know what happens.
Cheers, Lynno

Hi Lynno, if the polygons it's complaining about are very small it might not be a problem.

- Michael

the error is coming from the top edge of the vase. it is saying it's too thin. you can probably ignore it or fillet the edge to remove the sharpness.

Hi Lynno,
as val2 pointed out its the top edge.
I trimmed 0.1mm of the top to clean up and sliced it in Ideamaker no problem.
It would also slice without trimming after an auto repair is applied in ideamaker.

Hi,

My theory is that your problem comes from your "Vase mode".

Your object is a full solid and plain vase.

Your software wants to do the same thing as a "Shell" operation.
Without the patterns, it's OK, I think. but with it, this mode could give you some problems.

My advice is to do a real vase with your revolution surface (unselect the cap ends checkbox), and do a Shell on it (or do a surface of revolution with a closed curve with inside and outside.
Next you add the patterns.

A theory to be verified...

I don't see a problem in Cura. Your pattern sticks out too far creating overhangs though, which will result in holes on vertical surfaces.

Thanks everyone for your help. Phiro, re Vase mode: I've created some complex surface patterns using other methods, and although these have made the object difficult to shell, vase mode in S3D has handled it well. I'll use all these thoughts to make something more interesting, and see how I go :)
