This algorithm appears to minimize infill time while still supporting the shell during printing. That's useful for prototyping form or fit, but I feel like 3DP

This algorithm appears to minimize infill time while still supporting the shell during printing. That's useful for prototyping form or fit, but I feel like 3DP for prototyping has been beaten to death already. I would much rather have algorithms that can improve the performance of production parts. For FDM, that means infill algorithms that vary cell size and structure to optimize some user-defined metric, whether that's rigidity per dollar, per print time, etc. Just having denser infill near the shell like a bird bone would be a nice start.
