Lattice Infill fills the interior of your model with a repeating geometric structure. This reduces material while maintaining strength — and can create stunning visual effects for display models.
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
| Pattern | Style | Description |
|---|
| Cubic | Strut-based | Simple grid of axis-aligned struts. Clean, predictable look. |
| BCC | Strut-based | Body-centered cubic with diagonal struts. Stronger than cubic. |
| Octet | Strut-based | Dense network of struts. Very strong, uses more material. |
| Diamond | Strut-based | Tetrahedral connections. Organic, crystal-like appearance. |
| Gyroid | Smooth surface | Continuously curved surface. Beautiful organic look, excellent strength-to-weight. |
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 Cubic, BCC, Octet, and Diamond. Default: 0.5 mm.
Shell thickness (mm)
Wall thickness of the Gyroid surface. Only for Gyroid. Default: 0.6 mm.
Interior offset (mm)
Shrink or expand the lattice region relative to the model surface. Positive = shrink inward. Negative = expand outward. Default: 0.
Include shell
Toggle (default: on). Keeps the outer surface of your model intact around the lattice.
Surface mode (Gyroid only)
When on, creates a lattice band that conforms to the model surface instead of filling the entire interior.
- Band thickness — Width of the surface band
- Surface expansion — Push the band outward
- Fill interior — Also fill the interior below the band
Material color
Choose a color for the lattice geometry from 16 presets or a custom color picker.
Step by step
Select the Lattice tool
Click Lattice in the Interactive Tools section.
Choose a pattern
Click one of the five pattern tiles.
Adjust cell size
Smaller cells = denser, stronger lattice. Larger cells = lighter, more open.
Set thickness
Adjust strut thickness (strut patterns) or shell thickness (Gyroid).
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
Very small cell sizes with thick struts create extremely dense lattices that take a long time to process and produce very large files.
