Fig. 7.20: In contrast, this grid fill is composed of ‘lines’.

The grid arrangement (Fig. 7.19) is much stronger and can be difficult to remove. Lines can be removed more easily (Fig. 7.20), but have to be taken off one at a time. More recent versions of Cura offer further support patterns:

Concentric: this follows the outline of the overhung parts, filled in with concentric shells. It has the advantage of supporting well to the edge of parts.

Concentric 3D: instead of separate shells, the support structure is filled with a 3D mesh to make it much stronger.

Triangles: like a grid, but a bit more densely packed to provide very good support.

Zig-zag: like lines, but with alternate ends joined. This style is less likely to suffer from the failure of one of the fill walls than plain lines.
