Cura not slicing properly

[brottraeger 0]

Hi I am fairly new to 3d printign and I am trying to print a 3d Model. It looks like this.

 

when i go into the layer view the model has a lot of errors.

I read that the actual outcome can variate from the model if the printer can not print the shape e.g. to small edges. But in my case, huge parts are missing. 
I set the default profile for fine with 0.1mm layer hight.  The model is about 200mm.

What am i doing wrong and what can i do to fix that problem.

The model is non-manifold. The following plugin can try and fix those issues for you: https://marketplace.ultimaker.com/app/cura/plugins/fieldofview/MeshTools

Is this your model?  Or did you download it from somewhere?

 

If it's your model then you can fix it in your CAD software.  What CAD software did you use?

 

If not, try the mesh tools as nallath suggests or you can use the netfabb repair service (free web service but you have to create an account).

 

Also you can mess with the standard mesh options in cura.  I would try unchecking "union overlapping volumes" or checking "extensive stitching".  just toggle them all.
