Geometric Pattern Generator for Laser Cutting
Eight pattern engines in one studio — tileable girih strapwork, 8- to 18-fold aperiodic quasicrystals, hyperbolic tessellations, Islamic petal rosettes that double as medallion pendants, Japanese kumiko lattice panels, Celtic knotwork, traditional Japanese patterns and conformal spirals — with live fabrication checks for your kerf, material, and sheet size. Every export is real-world scale: a 100 mm square in the file is 100 mm under the laser, which is what the ruler along the edge of the bed is measuring.
Designing, previewing and validating are free. A one-time $49 purchase unlocks every export — score/engrave SVG, cut-lattice cut files, DXF for LightBurn, an STL for 3D printing, and project save/load — tied to your account, so it works on every device you sign into. The calibration square stays free: cut it first to confirm real-world scale before you buy.
New to these patterns? Read the guide to Islamic geometric patterns for how girih tiles, strapwork and quasiperiodic tilings are constructed — then build your own here.
Formerly Girih Pattern Studio — girih is now one of eight engines. Existing Pro unlocks and saved projects carry over unchanged.
Quick start
How to use Ornament Studio
Design and validate the pattern before purchasing. The preview, fabrication checks, and calibration file are available while you work.
Pick the pattern engine
Use Tileable for repeating panels, Rosette for radial star rosettes and medallion pendants, Aperiodic for non-repeating 8- to 18-fold quasicrystal panels and medallions, Hyperbolic for disc tessellations, Kumiko for Japanese lattice panels, Celtic for knotwork panels and borders, Japanese for seigaiha, shippo and other wagara, or Spiral to wrap any tiling into a conformal spiral.
Set scale and material
Choose units, finished dimensions, sheet size, material thickness, and kerf. The ruler and status bar report the real export scale.
Choose the physical output
Use Score / Engrave for line artwork. Choose Cut-Lattice when the ribbons must become connected cut parts.
Resolve fabrication checks
Adjust bridges, spacing, or pattern density until the status bar reads Export-safe. Do not export through red errors.
Download the right file
Use Score / Engrave SVG for line work, Cut-Lattice SVG for connected parts, or DXF for LightBurn and RDWorks. To 3D print instead, set a thickness and download the STL. Save the project if you want to edit it later.
Before the full cut: Download and cut the free Calibration square first. If it imports at the wrong size, fix the software's SVG/DXF unit settings before exporting the full pattern.
Eight pattern engines
Tileable strapwork cells that repeat seamlessly — Archimedean star panels, the Kashan star-and-cross, the Mamluk 9/12 stars, 18- and 24-point star panels, a 7-fold motif after Jay Bonner and repeating quasicrystals among them — true aperiodic quasicrystals from 8- to 18-fold — Penrose rhombs or kites and darts, the girih tiles of the Darb-i Imam shrine (in one level or two), or de Bruijn's multigrid with a star or rosette centre — in classic single-point or two-point strapwork, {p,q} hyperbolic tessellations projected onto a disc, and Islamic petal rosettes drawn with the same strapwork rule as the panels — add a border band and hanging hole for a ready-to-hang medallion. And kumiko lattice panels (asanoha, goma, kikko and more) cut as one piece, frame and infill at their own widths, and Celtic knotwork drawn as a plait with breaks, woven over and under, and Japanese patterns (seigaiha, shippo and more) on panels or coasters, and any tiling wrapped into a conformal spiral. Deterministic seeds — the same seed always rebuilds the same design.
Certified to hold together (Pro)
Most generators make pictures; this one makes parts. The cut-lattice engine turns patterns into real closed ribbons and mathematically audits the result before export — one-piece connectivity for stencils, kerf-adjusted bridge clearance, per-face diagnostics, and multi-sheet backing layers with glue-support checks — so what exports is what survives the laser.
Honest file formats
SVG with named operation layers (cut / score / engrave / frame) and configurable stroke colors, plus DXF R12 for LightBurn and RDWorks (Pro). Exports are polyline-based — no arcs — which is exactly what laser controllers execute anyway. No laser? The STL export (Pro) turns the same cut-lattice part into a watertight solid at the thickness you set, ready for any slicer, with a check for straps too thin to print. No repeating tiling can have true 7-fold symmetry, so the repeating 8- to 14-fold panels are periodic approximants: locally quasicrystalline, built from the exact rhombs, and repeating on a rectangle.
