[Unwanted top layer - or: how to use horizontal layers inside model without a final top layer]

THX everybody,

 

so there is no setting to tell Cura to:

a) print horizontal geometry

and

b) not "invent" or "add" additional geometry?

 

All the detail is essentially there....

The shell has no "depth" since it should be printable with a single layer. That seems only possible without a given depth, since no fixed nozzle-size is required.

 

I might try the blender way though....

 

For now i help myself with some "cut meshes" that enable the top/bottom layers at some key-points.

Not perfect, since those cut-meshes generate a top/bottom-layer themselfes, but that layer is not as extensive as a top/bottom layer over the whole wing.

(other cut-meshes enable a second wall at the start and end of each wing-part)

 

That kinda works for the wings. I haven't looked at the fuselage yet.

[Unwanted top layer - or: how to use horizontal layers inside model without a final top layer]

Hi,

 

i have a big problem printing some STLs. The STLs are open on bottom and top. However, when i enable the top/bottom layers in cura, cura closes the bottoms and tops.

If i disable bottom/top layers by setting them to 0, cura also does not print some horizontal parts inside the model that should be there.

 

This is my test-part: https://www.thingiverse.com/thing:2115282/#files

Cura 3.1 is used.

 

I made some screenshots:

1: In solid view you can see the horizontal part in the blue circle.

2: with top-layers enabled, the model is closed on top (but should be open)

3: inside the model now looks good

4: without top layers the part is missing

 

So it seems that either i can

a) have the model open but parts missing

b) have the model closed but inside its OK

:-(

 

I already tried the "cut mesh" tricks: the mesh-part where i have to enable the top-layers always inserts an artificially inserted closed top/bottom layer at its boundaries -> no help there.....

 

Any help is greatly appreciated!

 

Greetings,

Markus

[Need help with thin wall printing in Cura]

So I hope this helps you. Sorry its so long winded, and took so long to get back. I am no expert, I can only pass along what I have learned that worked for me. I hope these help you. If not, maybe you have Hot end issues.  I have seen people comment on Hot end issues simply saying "Maybe you have hot end issues" but I have never seen a good example of what a hot end issue actually is. So I dont really know how to advise of there is actually an issue with your hotend.

As a "not-yet-printing-this-model" reader i would just like to thank you for posting this very nice "how-to-optimize" guide.

Very helpful!
