Interlocking layers is an interesting idea, but I don't see how this is supposed to work.

You can't use the nozzle to inject that much filament into a large cavity because it will cool and solidify right out of the nozzle. Anyone who has ever cleaned blobs of filament off of a nozzle after a print failure can tell you what happens when you try to pump hot filament into empty space. Filament cools below the melt temperature quickly, especially when it comes into contact with your print.

At least the README admits that it doesn't work:

> What’s NOT yet working: the physical print. On my Ender, same-material plastic injected into freshly-printed cells melts the cell walls before they can seal. The math says this should work; the materials science is the open question.

I like seeing experimentation, but this is a lot of software work dedicated to something that couldn't possibly work. I'm curious about "the math says this should work" combined with the large number of em-dashes and other LLM tells. Was this experiment largely driven by an LLM?

There is some interesting work on the topic of staggered interlocking layers: https://github.com/OrcaSlicer/OrcaSlicer/pull/8181

Reading any of the research on that should make it obvious that you can't "inject" molten plastic into larger cavities, though.

		It's always a balance of tradeoffs and benefit. That might work, but there are already alternatives. If possible, change the design so that the anticipated load is acting on the x and y axis of the print. If that's not possible, another common tactic is to do something like partial print > insert metal rod in printed channel along y axis > resume print.
