Why layer view is not showing the object properly? What's the issue?

[zymmetry 0]

Hi,

 

I'm totally new to 3d printing and I don't know why this is happening right now. I spent ages drwing this properly and accurately in blender and it looks good I think but obviously not the best one... Why some lines (like in the back) are broken in layer view? Will appreciate any help, cheers!

I'm pretty sure it's because the model is too thin there for your settings.

 

As a quick check - set the nozzle width to half of what it is now to see if that helps.  If it does then it is related to those thin areas of your model.

 

You can also try the option print thin walls.  Check that box in cura.  If that's not enough try lowering you line width parameters.  If your nozzle is 0.4mm you can go down to 0.3mm line width without a severe loss of quality.  Certainly 0.35mm is fine.

 

As a general rule, any wall you print needs to be 2X the width of the line width parameter.  Or at least 1X if you check print thin walls. 

 

If I'm completely wrong and this makes no difference then please post your project file (do menu "file" "save project..." and post that here).

This totally makes sense because I forgot to made those spots thick enough! Will give few tries and then update back. Thanks a lot!!!

The model is also non manifold, which can also cause additional issues.

I'm pretty sure Nallath is referring to the little red arc in the picture that shows your model mostly as blue and white.  There should be no red.  It might not matter.  But that red area is non-manifold in some way.  You may or may not have to fix that small spot.
