Posted · STL file and Cura rendering very different from printed result!

I'm having a rather frustrating issue with Cura that I can't figure out. I designed a replacement bottle screw cap in Autodesk Inventor 2013. Simple enough, but when I try to print it, Cura fills in the screw-thread area. If you look at the picture, both the Cura rendered model, as well as the originally Inventor model clearly show the bottle cap center portion is clearly shown to be hollow. However, as you can tell from the "layer" view, Cura is filling in that space for some reason when it tries to print. Unchecking "solid infill top" or setting fill density to zero does not help. I have used this same technique in the past without issue, but I just don't understand why it wont work now. Ideas?

 

Bottle Cap

Here is the STL file:

    I guess that when you uncheck every one of the four boxes in the combine everything options it will work fine. You can find these boxes in the lower right of the expert settings.

    It usually works for me. Only once it kept in filling some of the layers.

    Have fun. Gr Cor.

    Hi,

    It looks like it prints an inner cylinder with thread inside ?

    Have you tried playing with the fix horrible check boxes sometimes it makes a difference

    Maybe check your STL in netfabb or in meshmixer maybe, a wild guess here: maybe flip normals (you can do that in meshmixer)

    Most likely there are some extra internal faces in the model, causing cura to be confused about what is inside and outside the model.

    I think (unsurprisingly) Daid was right on. I am using a thread modeler plugin in Autodesk Inventor, and while many of the threads it generates have both rendered and printed perfectly, after I ran this one through "repair" in netfabb, it printed correctly the next attempt!
