[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 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.
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.
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.
