Trying to get my head around why this 3D model I've created in Rhino won't slice in cura.

Every time I import it into cura and slice the object for 3D printing it keeps only showing the first and last layers (as shown in the image)Capture3.thumb.PNG.4fb4ab5f263e365a552005ce637d7790.PNG

Any suggestions on what to try would be much appreciated.

    It could be that you created walls too thin to print - test that by setting your line width to 0.1mm temporarily to see what happens.

     

    But much more likely your model isn't manifold.

     

    Cura has an amazing plugin to test your model to see if something is wrong with it and can repair a very few of the many potential problems:
    In the upper right corner of Cura click "marketplace" and make sure you are on the "plugins" tab and install "Mesh Tools".  Then restart Cura.  Now right click on your model, choose "mesh tools" and first choose
    "check mesh", then "fix model normals" and "fix simple holes" to see if that helps.  Cura doesn't fix most issues so...

    netfabb free repair service is here (you have to create a free account first):

    Hopefully someone who knows Rhino can help you.  Perhaps Rhino has a forum of people who know how to make sure objects are manifold.  Most CAD software won't let you create non-manifold objects.  However a few like sketchup, freecad and blender will do so happily.  I use DSM which simply only lets you create solid parts - not impossible shapes that can't exist in in real life (only in computers).

    I believe I found a use for "Mesh Fixes | Remove all Holes".  The back legs aren't on the build surface and require support.  I randomly set it to 10% scale because it came in sized for a Jolly Green Giant.  Sinking it into the build plate 2mm worked to flatten the bottom.  I'd use a brim because the contact patches of the rear legs is pretty small for the lean angle they end up at before they merge into the rest.
