What does that have to do with 3d printing?This reads like just another slop article, repeating a bunch of platitudes in different ways. Sure it has some facts, but could have been way shorter and more concise, or the same length and much more informative.
I’ve found 100% infill weaker than something like 60%, it won’t break per se, it would delaminate. Also number of walls is really important you can dial down infill to 20-25% if you have 6 walls or more.
I often print 3 walls and 10% infill and the prints are plenty strong. These are not high stress objects, but they can take plenty of stress without breaking.
I did print some curtain rod holders for some outdoor curtains. They had 3 walls and I think 25% infill. They do get a lot stress from the wind blowing, but they have held up very well in the 3 months they have been up.
