Any pattern. Any surface. Ready to print.

Latticework is a single Geometry Nodes group that fills anypanel with a raised lattice screen — a jaali, a grille, a louvre, a ringmesh, a Moroccan trellis, a rose window, a sunflower spiral — cut exactlyto that panel's own outline and sized to come off a 3D printer.

Drop it on a plane and you get a screen. Drop it on a folded corner, aneight-facet bay or a curved bay and you get the same screen, runningunbroken across every fold.

Built and verified on Blender 5.1.

It works on the surface you actually have

Most lattice tools want a flat rectangle. Latticework has two layouts, andthe second is the reason it exists.

Planar rules the bars in a single plane. Exact and cheap,and correct while the panel really is flat.

Unwrap flattens the panel, lays the pattern out on the flat,trims it there, and folds the result back. The pattern runs unbroken acrossfolds, and the trim is exact — because on the flat, “is this pointon the panel” is an ordinary in-plane test.

A developable surface — a fold, a bay, a cone, a drum —flattens without distortion, so Unwrap does not stretch the pattern at all.

The cut is exact. The first point past the edge is slid backalong its own segment until it sits on the boundary, rather than being deletedwhole. A panel 1.6 wide measures 1.6000 at any Detail setting from 0.005 to0.12, and Overrun adds exactly twice itself.

Watertight, and measured — not assumed

Every edge has exactly two faces. No boundary edges, no pinched vertices,normals outward. That is measured on all 28 example panels on everybuild, by an audit that runs as part of the build script — notclaimed and hoped for.

Bars are swept along centrelines, not cut out of asubdivided sheet. A bar's sides come from its profile, so they are exact at anyangle — no staircasing. Bars cross by passing through one anotherrather than sharing cells of a grid, which removes a whole family ofnon-manifold failures at the crossings.

The output is an assembly of overlapping closed solids, each individuallyclosed and watertight — which is exactly what a slicer wants, becauseslicers union overlapping closed volumes. If something downstream cannot takeself-intersection, one Remesh switch gives you a single cleansurface instead.

Actually designed for printing

The screen is raised on a solid back, not perforated. Atsmall scales a pierced screen's openings fall below the nozzle and close upanyway — and relief has no holes to bridge and no unsupported spans, so apanel prints face-up with no supports and no orientation puzzle.

Print guidance ships in the README, with the rules that matter:

• Rib Width ≥ one nozzle width as printed, ideally two.
• Pitch − Rib Width ≥ one nozzle width, or the recesses fill in.
• Relief ≥ two layers, or the lattice will not read.
• Overrun into a surrounding frame rather than stopping bars on the outline.
• Bevel takes the wire edge off an arris that would otherwise print as a burr.

The lattice deliberately bites a quarter of the way into the backing ratherthan sitting on it, because coplanar walls are what make a slicer split ashell.

Three ways to arrange the bars

Parallel — crossing sets of straight bars. One familyis a louvre, two a lattice, three gives hexagons and six-pointed stars.

Phyllotaxis — a sunflower spiral. Points sit on thegolden angle at radius c√n, which gives every point an equal share ofarea, so the packing stays even from the middle to the rim. Both families comeout of one set of points grouped two different ways, and consecutiveFibonacci arm counts cross at roughly a right angle — which is what makesit read as a lattice rather than a swirl.

Radial — rays and the rings between them. A fanlight,or a rose window. Both families again come from one grid of points, so thesecond costs nothing.

Run curves: the pattern along the bar

Bars do not have to be straight. Give them a run curve— one drawn period — and they meander, scallop, ogee or repeat anymotif you draw.

Closed motifs get stamped rather than stitched, and the overlap isthe pattern: that is how you get a ring mesh, or the interlocking quatrefoil ofa Moroccan trellis. Run Stagger gives you a brick bond;Family Phase offsets each family against the last.
