Symmetric infill Y axis

Flips the infill pattern like a mirror, across the Y axis. It's so two symmetric parts (left and right) also get a mirrored infill texture.

Not always visible. In Bambu Studio this setting only shows up when “Sparse infill pattern” is “Zig Zag” or “Cross Zag” or “Locked Zag”. See Sparse infill pattern.

How it works

With “Zig Zag”, “Cross Zag” or “Locked Zag”, the infill leaves a visible texture if the faces are left open or the filament is translucent. If you print a part and its mirror twin, that texture won't be symmetric: the pattern is drawn the same way in both. If you turn this on for one of them, its pattern flips and the pair matches.

When to change it

  • A pair of left and right lampshades, or the two wings of a decorative plane printed in translucent filament: turn it on for just one of the two.
  • Everything else: off.

Watch out for

  • Turn it on per object (“Objects” tab), on the part you want to flip, not in the global settings.
  • It only shows up with “Zig Zag”, “Cross Zag” or “Locked Zag”.

What Bambu Studio says

If the model has two parts that are symmetric about the y-axis, and you want these parts to have symmetric textures, please click this option on one of the parts.
