minimal-surface infill, under your control
Start from one, then change anything.
Thickness of the printed sheet, in mm. Match it to your nozzle (or a multiple of it) and the slicer will trace it exactly. Below about 1 mm, set the sample cell to match — the button under Resolution does it for you.
Different values per axis stretch the cell — the lattice no longer has to be square, and no longer has to line up with the print bed.
Cell size sweeps from the value above to this one across the object. The sweep is integrated analytically, so the pattern stays continuous — cells grow, they never tear or restart.
Wall thickness varies through the volume instead of staying constant. Cells keep their size; the sheet gets heavier or lighter.
The lattice is rotated and sheared independently of the object and of the build plate.
Faces you leave off stay open, so the infill is exposed on that side — which is what you cast against.
Slice the preview open to look inside — the same view the slicer gives you of a half-filled cube.
Turn either on if the view spins the opposite way to what your hand expects.
