Script causing 3Dfabrication quality Issue?

Hey guys.

My attempts in 3D printing this geometry (green) is failing although I've used the same basic SMorph script on another geometry and the print quality came out just fine.

Every time I test the print with Makerware by Makerbot, the layers are extremely stringy and low in quality.

I've tried uploading it to netfabb cloud to have the stl fixed and it does nothing. Beginning to wonder whether or not there's something in the script that's causing this problem.

Anybody knowledgeable in 3D printing have some insight at all? Direction of any sort is appreciated. This is killing me.

Below is a successful print using the same basic script + trigrid.

when you say "stringy and low quality" do you mean the layers have a good outline but the fill is not consistent? Or are the layer outlines no good too? If you have lots of acute angled outlines and try to fill them with say a 0.5mm extruder nozzle diameter then the software may be having problems filling right into the corners?

The problem is maybe to do with how the makerbot software handles the geometry rather than the geometry itself so you might be better off contacting them to see if they can handle your model.

The Morph components can easily create self-intersecting and non-manifold geometry if you are applying them to a complex surface. I would guess there is something going on in that point where everything pinches together. Have you run the mesh analysis tools in Rhino? Have you checked if it is a closed, manifold mesh?
