Mid-Solid Raft?

[profshanks 0]

When I slice this file (Basetta_A.stl) it introduces a strange "raft" into the middle of the solid. I have attached photos here.

 

It is really odd; the slicer creates a top to the bottom section, then a raft-like-structure, then a bottom to the top section. You can see this in the preview, and nothing that I change in the settings seems to affect it. I have tried no-structure, no-adhesion, different layer heights, different wall thicknesses. I am stumped.

 

Do you know what is triggering this? I even tried using a different slicer program (ideaMaker), which eliminated the raft, but the results were otherwise hideous. 

 

I would like to get this fixed within Cura if at all possible.

 

The origin of the file was "Skyrim Dragon" on Thingiverse.

 

Many thanks!

Hi, I'm afraid the model has errors, it's not watertight. Install the cura mesh tools plugin to get warnings about bad models.

I did get a message stating that the model was not manifold. Is there anything that I can do to make it watertight?

I am not aware of anything in Cura to fix that problem but maybe some other tool can help. It's not my area of expertise but I think, in general, one has to go back and edit the model to fix issues like this.

Get the Mesh Tools plugin and right click, and click on 'Fix Model Normals' and 'Fix Simple Holes'.
