Generating a gyroid lattice with the Lattice tool
When to use this
- For artistic lattice effects on display models
- When you need precise control over internal structure
- To reduce material usage while keeping strength
- For models where you want the lattice to be visible
Lattice patterns
The result
Applying a lattice replaces the model’s solid interior with the pattern you chose, while keeping the outer shape intact. The exterior looks like a normal print; slice into it to see the repeating structure inside.The finished gyroid lattice

Settings
Cell size (mm)
The size of each repeating unit. Smaller = denser lattice. Default: 5 mm.Strut thickness (mm)
Diameter of the connecting struts. Only for BCC, Octet, and Diamond. Default: 0.5 mm.Shell thickness (mm)
Wall thickness of the outer shell — and, for the Gyroid and Schwarz-P surfaces, the TPMS surface band. Default: 1.0 mm.Interior offset (mm)
Shown only when Include shell is off. Shrink or expand the open-cell lattice region relative to the model surface. Positive = shrink inward (leaves a gap). Negative = expand outward past the surface. Default: 1.0 mm — but when you turn Include shell off, this auto-sets to -1 mm to extend the lattice out to the surface. With Include shell on, the lattice domain is automatically eroded by the wall thickness, so this control is hidden.Include shell
Toggle (default: on). Keeps the outer surface of your model intact around the lattice.Band thickness (Fill Mode)
Controls how much of the interior the lattice fills. Default: 0 = fill the entire interior. Set a value greater than 0 (typically 3–6 mm) to fill only a band just inside the shell — faster and lighter, leaving the body hollow inside.Step by step
1
Select the Lattice tool
Click Lattice in the Interactive Tools section.
2
Choose a pattern
Click one of the five pattern tiles.
3
Adjust cell size
Smaller cells = denser, stronger lattice. Larger cells = lighter, more open.
4
Set thickness
Adjust strut thickness (strut patterns) or shell thickness (Gyroid).
5
Apply
Click Apply to generate the lattice.
Tips
- Gyroid is the most popular choice — strong, beautiful, and prints reliably
- Cell sizes below 3 mm may be too fine for FDM printers
- Use interior offset to prevent the lattice from touching the outer surface
- Use the Slice View tool to inspect the lattice interior
