Model Responsive Infill

[nihlton@gmail.com]

Would be neat if the infill would respond to the shape of the model - providing more granular infill toward the edges (for better top layers) and more open space toward the center (to save time + filament)

One possible solution would be a 3D dimensional voronoi diagram.

Randomly generate a point cloud of the model's volume, with weight added toward the edges, then generate the voronoi pattern around the point cloud.

like:


we could then have sliders for total point density, and edge weighting.

Greater edge weight would mean larger gaps in the center, and smaller pockets toward the edge. zero edge weight would produce uniform pockets.

if you guys are good, you could have an 'infill volume' slider, and figure out the point density from there

I realize this could potentially add *minutes* to the slicing process, but the output would produce much stronger models with less filament, and potentially in less time.

If I'm prepping for a 12 hour print anyway, an extra 5 minutes isn't a problem.

I would love to see this feature!

This is a very interesting idea and seemingly a good solution to the problem. I'm not sure I'd hold up the next release for it (which is right around the corner, right guys? Right? RIGHT?), but I'd certainly like to see it on the list of things you start looking into actively.
