Printing surfaces

[celso-santos 11]

Why Cura cannot print open surfaces ?

It understands close surfaces and even gives us the chance to choose the wall width. It would be great if we could print surfaces. We should just define the direction that the wall should grow from.

Hi Celso,

The slicing process take a slice of the geometry and create polygons from it along the that z height. If the slice is not closed than it can't properly define how the face behave. Since the system doesn't create volume (it uses volume) then it will create random results.

How could the software tell that this section need to grow and the other need to be constrained to the available space?

There is an option in the expert settings to keep the open faces. I don't know if it will do what you want but you can try. The thing with the wall width is that it doesn't create geometry. It just fill volume available with a shell thickness and leave the remaining space available for the infill mostly to save material and print time.
