Voronoi Pattern Generator
Fill a rectangle, a circle, a heart or your own shape with a cut-out pattern — Voronoi cells, honeycomb, squares or diamonds — and download an SVG for your laser. The panel always stays in one piece.
A rectangle, a circle, a heart — or upload the outline of your own part as an SVG.
Pick Voronoi, honeycomb, squares or diamonds and set the cell size, line thickness and frame.
Download the SVG with one red cut line in real size in mm. Small slivers that would burn away are removed for you.
Voronoi pattern for laser cutting
A Voronoi pattern looks like cells, dragonfly wings or cracked earth, and it is one of the most wanted fills for laser-cut lamps, screens, coasters, trivets, speaker grilles and decorative panels. The generator builds the cells, keeps an even line between them and joins everything with the outline of your shape into a single part.
Which line thickness should I use?
For 3 mm plywood keep the lines at 2.5–3 mm or more; thinner lines char and break. Acrylic and MDF allow slightly thinner lines.
What does Evenness do?
At 0 the cells are completely random, with very small and very large ones side by side. Higher values make the cells closer in size, which looks calmer and is stronger.
Can I use my own shape?
Yes. Upload an SVG with a closed outline. Inner outlines stay as openings, and the pattern keeps the frame distance from them too. The file stays in your browser.
Is it free?
Yes. The generator runs in your browser, and you can use the result for personal and commercial projects.
