Star Polygon Lattice
A parametric lattice built from star-polygon unit cells. Each cell is a small star whose arms tile outward through a repeating grid; you pick the cell style (M1–M4), the star's interior angle, and how many cells fit along the length and width. The result is a light, rigid structure useful for infill panels, orthotic lattices, or decorative flat stock.
See Predefined Models for the general workflow and how to select this model.
Parameters (sliders)
Parameters
Lattice Type- Unit-cell geometry: M1, M2, M3, or M4. Each style packs the star polygons differently — M1 is the densest, M4 the most open. Try them side by side to pick the look you want.
Star-Polygon Angle- Interior angle of the star polygon in degrees (15–150). Low angles (20–40°) give sharp, spiky stars; high angles (120°+) give blunt, hexagon-like cells.
Strut Length- Length of each strut (mm) — effectively the side length of a single star polygon. Controls the physical size of every cell.
Length (Unit Cells)- Number of unit cells along the X axis (4–15). The printed length equals Strut Length × this count (approximately).
Width (Unit Cells)- Number of unit cells along the Y axis (1–5).
Layers- Number of vertical layers (1–5). Each layer reprints the same lattice path at increasing Z — use 2–3 layers for a rigid panel.
Quantity- Number of lattice panels generated in one job (1–5).
How it works
- The unit cell is generated from a star polygon with Star-Polygon Angle interior angle and Strut Length side length.
- Cells are tiled according to Lattice Type: each of M1–M4 has a different translation/reflection rule for placing adjacent cells.
- The toolpath walks the entire lattice in one continuous polyline (the print algorithm optimizes the traversal order so there are few travels).
- Layers extrude the same path at multiples of the layer height, giving a solid flat panel.
