It seems to me that out of all the various magical settings involved in the typical FDM print infill has got to be the most ethereal of them all.
It's also the one that can change the material quantity consumed the most, product weight, print time the most, and probably the most important thing it controls is the product's strength.
I'm not looking for the precise result of a specific infill percentage but just a rough guidance.
What are your rules for messing with the infill percentage?
I doubt 50% infill makes a part 50% as strong as 100% but what does it do, 25% of the strength or 75%?
Paint me curious.
