I think print infills are for most of us a bit mysterious. We all have a favourite, which we think is better, faster, stronger, than the others, but it’s mostly based on our instincts. No real facts, mostly just feelings.
I wanted to see, know and prove, which is the best! So I went for a new kind of infill project, that I haven’t seen yet. Here is it:
- took a spool of eSun 95A TPU
- prepared 16 cubes sized 30x30x30mm
- no perimeters, no top layers
- only 2 bottom layers (max 0,4mm total)
- allocated all Prusaslicer infills to one cube with 15% infill
And I think the results are impressive.
The two stiffest ones are cubic and gyroid, but cubic is stiffer and much faster! Printing the same size of infill takes 50% longer with gyroid (have a look at the attached chart).
The conclusion:
- Cubic is the stiffest one! And as it is very filament efficient and quite quick, this is my new favourite!
- if you look for filament efficient option, go for adaptive cubic. It’s still quite strong, but very quick and efficient!
I hope it helps you all!
