[JanTec Engineering] was fascinated by the idea of using a 3D printer’s hot end to inject voids and channels in the infill with molten plastic, leading to stronger prints without the need to …
I think the point here is to have a part stronger than a 100% infill part. But you are right, 3D printing filament is very expensive. I have recently posted a project where I use plaster as a fill material.
I mean if you had another nozzle with some cheaper materials this could work. I have done something similar where I had used an infill with very large gaps, put a pause in the print and filled it with hot glue. I’ve also seen prints where it was essentially hollow and this filled with concrete.
filament ain’t cheap enough to go running around printing things at 100% infill

My first benchy boat I made with 100% infill and I could stand on it without it breaking.
