[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 …

    This person should probably have watched this video first that posted here yesterday. 80% infill seems to be about the break even point for the biggest gains. No 100% infill really needed in the real world of FDM.

    Something, something, 80% rule strikes again and just because you can do something doesn’t mean you should.

      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.
