Model with mixed surface and thickness geometry

Recommended Posts

Posted · Model with mixed surface and thickness geometry

Hi all,

I have model that outer geometry is surface and inner geometry are thickness ribs.

Now when I put it in my Cura 2.6 for Ultimaker 2, it only slice outer surface without inner ribs.

I have tried in Special Modes, under Surface mode select every option there is (both, normal, surface), but Cura only shows outer surface as sliced geometry.

How to make it work, to print both surface and inner ribs?

Cura is probably getting very confused about the zero thickness wall. Check the xray view and I'm betting you'll see a lot of red problem areas.

The model should be a proper manifold solid, not a surface body, to slice properly.

Unfortunately the model is as it is (I bought stl files), so I can't do much about it...

Here is Xray view, it only shows bottom and top red.

I was working with another user some months back with a similar issue on a purchased model with zero-thickness walls. He found the following allowed it to be sliced, but I did not hear if it actually printed correctly:

  • Uncheck all options under "Mesh Fixes"
  • Set Merged Meshes Overlap to zero (0)

Maybe that will work for you.

Yes!, that did the work, now Cura finally shows inner ribs when sliced.

Now off to test 3D Print!

Thank you!

Just to report feedback.

It worked!

Now only to resolve stringing and it will fly to the sky
