Cura "invents" some layers in my 3d model

[Agus_3d 0]

Hello, 

I've came here asking for help with my 3d model. The problem is that my 3d model (stl file) looks nice until I go to the layer view, then I get noticed that it creates some layers from nowhere. Here there are some screenshots:

 

As you see, Cura creates some layers and I don't know where is the problem. I hope someone could help me to delete them because I have tried to change some edges or points (i thought they could be making trouble to Cura) but nothing of that worked.

 

I designed the model with blender (maybe that is important, idk)

If you inspect your model in X-Ray view (which is - strangely - hidden away in the Preview stage), you will probably see that there are geometry errors in your model. Your model likely isn't "watertight".

Yes, when I opened it with Cura I saw the notification that wasn't "watertight", but when I inspected my model with X-Ray view I coulnd't understand nothing, it was like everything with different tones of blue and purple. What can I do? Because in blender everything seems fine (not infinite thin walls, not any point or edge lost/repeated...)

 

Thanks for answering

The model probably has a small hole or gap that is throwing off Cura. It needs to be "repaired". If the hole is small enough, perhaps the Mesh Tools plugin "Fix small holes" works. If not, you could try Meshmixer or Netfabb or another tool that comes up when you google "3d model repair".
