Infill pattern
In Bambu Studio, the profile 0.20mm Standard @BBL A1 sets it toGrid
The shape the plastic draws inside the part. At the same percentage, each pattern changes strength, time, noise and how well it supports the top; there's no single best one.
How it works
The inside of a part isn't solid: it's filled with a repeating pattern that supports the layers above and adds stiffness. This setting picks that pattern. Bambu Studio has 22, which fall into a few families.
The straight-line ones (grid, triangles, tri-hexagon, line, rectilinear, cross hatch, zig zag) are fast and stiff across the layer. The 3D ones (cubic, adaptive cubic, gyroid, 3D honeycomb) spread strength upward too and support tops better. The savers (support cubic, lightning) put plastic only where something needs holding up and leave the part nearly hollow. The decorative ones (concentric, Hilbert, Archimedean, octagram) are picked for how they look.
“Grid” (the default) is the balanced choice for almost everything. Some patterns come with their own settings that only appear when you pick them: “Zig Zag” (rotation on each layer), “Cross Zag” (shift), “Locked Zag” (skin and skeleton), “2D Lattice” (angles). On top of that, “Rectilinear”, “Aligned Rectilinear”, “Zig Zag” and the two zags support conformal infill.
When to change it
- A box, an organizer or almost any everyday part: “Grid”.
- A TPU case, a part that flexes, or a print you want quieter: “Gyroid”.
- A large tool holder: “Adaptive Cubic”; a medium part that takes force from any side, like a knob: “Cubic”.
- A large figure or decorative planter where all that matters is a good top: “Lightning” or “Support Cubic”, and you save a huge amount of plastic.
- Infill at 100%: “Rectilinear”, which leaves no gaps and doesn't pile up lines.
Typical values
| Value | What for |
|---|---|
| Grid | Default; fast and stiff across the layer; noisy above 40%default |
| Cubic / adaptive cubic | Strong in every direction; adaptive saves plastic on big parts |
| Gyroid | Same in every direction, quiet, good for flexibles |
| Rectilinear / line / zig zag / cross hatch | The fastest; weak in the other direction |
| Triangles / tri-hexagon / honeycomb / 3D honeycomb | Very stiff across the layer; slow and noisy |
| Support cubic / lightning | Only hold up the top; minimum plastic, hollow part |
| Cross zag / locked zag / 2D lattice | Their own settings: interlocking, skin and skeleton, lattice |
| Concentric / Hilbert / Archimedean / octagram | Decorative; for parts where the inside shows |
Watch out for
- “Grid” above 40% makes the nozzle bump into the crossings: switch to “Gyroid” or “Cubic” before slowing down.
- “Gyroid”, “Honeycomb” and the decorative ones take longer to slice and produce heavier files.
- “Lightning” and “Support Cubic” leave the part hollow: they're no good for anything that carries load or will take screws.
- At 100%, only “Rectilinear”, “Aligned Rectilinear”, “Concentric” and the surface patterns (monotonic, Hilbert, Archimedean, octagram) are allowed.
