problem with slicing a model

[Lightboxx 0]

hello,

 

why is this happening when i try to slice a model.

 

i made this model and exported it as STL. but when i try to slice it parts are missing.

Did you check if the model is manifold? It looks like the model has errors in it.

not sure what that means im pretty new to cura.

 

you mean overlapping faces?

 

around the eye are some areas where faces from the skull overlap with the eyeballs, yes.

the eyes are seperate in the original model for animation.

 

is there an option in cura to just ignore the internal structure?

to only look at the surface and treat the internal volume as solid?

If you have those kinds of areas Cura isn't always able to correctly identify them. Overlapping or disconnected faces can cause issues like the one you see.

 

Your best option would be to check out some model repair services and see if that fixes the issue.

i can correct that myself (when i know what casuses it). i model for two decades but i am new to 3d printing. 🙂

 

i have downloaded a few STL files from thingiverse and they had errors (open edges etc) but sliced perfectly.

so i thought the slicing software is very forgiving. but now i see what is probably causing the issue.

 

i have not modeled this head with 3d printing in mind. but it should be no problem to fix this area of the model.
