Interlocking depth

How far the beams of one material reach into the other, measured in cells. Too little grips poorly; too much mixes the colors more at the border.

How it works

Interlocking is calculated on a grid of cells; this number says how many cells on each side of the border get beams. With 2 (default), the beams reach in far enough to grip without spreading too much.

With few cells, the bond barely improves.

When to change it

  • To start: 2 (default).
  • A TPU-on-PLA wheel that still comes apart: 3–4.
  • A two-material logo whose border must stay very clean: 1, accepting less grip.

What Bambu Studio says

The distance from the boundary between filaments to generate interlocking structure, measured in cells. Too few cells will result in poor adhesion.
