Maximum length of sparse infill anchor

In Bambu Studio, the profile 0.20mm Standard @BBL A1 sets it to20, false

The hard limit, in millimeters, for infill anchors. At 0 nothing is anchored and every line ends loose.

Not always visible. In Bambu Studio this setting only shows up when “Sparse infill density” is greater than 0. See Sparse infill density.

How it works

Anchors join neighboring infill lines with a short segment that hugs the wall. “Length of sparse infill anchor” says how long that segment can be, as a percentage. This setting adds a limit in millimeters that's never exceeded, and it also turns anchors on or off: at 0, they're gone.

At 20 mm (the default), the limit almost never kicks in: regular anchors are a couple of millimeters long.

When to change it

  • The usual: leave it at 20.
  • A large decorative figure with very low infill, where you want the fastest infill possible and don't mind it gripping the wall less: 0.
  • A part where long anchors leave marks on thin walls: 5, for short anchors.

Watch out for

  • At 0, the “Length of sparse infill anchor” setting disappears too.
  • Without anchors, the infill holds on to the wall less well, especially at low densities.

What Bambu Studio says

Connect a sparse infill line to an internal perimeter with a short segment of an additional perimeter. If expressed as percentage (example: 15%) it is calculated over sparse infill line width. Slicer tries to connect two close infill lines to a short perimeter segment. If no such perimeter segment shorter than this parameter is found, the infill line is connected to a perimeter segment at just one side and the length of the perimeter segment taken is limited to infill_anchor, but no longer than this parameter. Set this parameter to zero to disable anchoring.
