Grey areas

[Humblebee 0]

Hello,

 

I've got several models from the internet (STL file), and when I place it in Cura 3.6 it is okay. I have to scale them down or up to be in the right size. When I slice it and I look in layer view, then I see grey areas in the model. So this area's won't be printed. How can I correct this, or is there a setting I should look at?

A screenshot of what you are seeing is important as there are several grey areas that you could be referring to that are normal.

This is the screenshot. The blue line is the real model, but as you see, there are grey areas that should be yellow (see the wings). 

How can I solve this problem.

I wish everyone a happy new year.

These parts are too thin to print, for a circle, printed with a 0.4 nozzle, the diameter becomes 0.8. And they will not come out nice and strong if they would print this thin. Maybe add something solid to the model when printed, like a piece of filament, stick (wood, metal).

Thanks. I will try, or edit the model.
