Voronoi Cutout
Prints only Voronoi cell edges; the interior of each cell is a travel move (no extrusion), producing an open web or lattice. This is the former Voronoi → Outline mode, now a dedicated effect under Cutout.
For raised ridges on cell boundaries without holes, use Voronoi (bump only).

Parameters
Cell Size- Density of Voronoi cells. Smaller values = more, finer cells.
Ratio (W:H)- Width-to-height proportion of cells on the unwrapped surface.
Jitter- How randomised seed placement is (0 = regular grid, 1 = organic).
Edge Width- Threshold for what counts as “interior” vs edge. Higher values leave more material on the printed web; lower values make larger open cells.
Seed- Changes the pseudo-random cell layout.
Phase- Rotates the pattern around the circumference.
Spiral (deg)- Helical twist of the pattern along height.
How It Works
At each toolpath sample, the engine compares distances to the nearest and second-nearest Voronoi seeds. Where that edge metric exceeds Edge Width, the point is treated as inside a cell and extrusion is skipped (travel only). See Voronoi for the same UV / hash setup.
When Voronoi Cutout is enabled, the wall path uses finer spacing between samples (scaled from Edge Width and profile radius) so the cutout boundary is smooth in preview and G-code. Very thin Edge Width values still need enough samples to resolve the web—if edges look faceted, increase edge width slightly or reduce cell density. Layer height still controls vertical stepping on the physical print.
