Strength Characteristics Graphene can be 10 times stronger than steel at 5% density.
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.

What a load of AI slop. We can do bether than this!

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.

CNC Kitchen did a video a few years ago demonstrating that infill percentage has little to no effect on part strength, provided the rest of the print (walls, floors, ceilings) has enough material to grab on to.

This is a pretty slop-py article.

It's not always this simple, but generally higher wall counts>infill percentage for strength and durability (and filament use)

[-] prex@aussie.zone 0 points 3 weeks ago

It would be cool to have a variable density infill that reduces with distance from the wall. Not sure how that would work in practice with most infill types.

OrcaSlicer has things like Adaptive Cubic or Lightning patterns that have more infill near the walls.

The other members of that slicer family (BambuStudio, PrusaSlicer, etc) likely have them too.

Lightning infill is absolutely bonkers WRT material efficiency and print speed for large parts. It doesn't offer the same level of strength as something like adaptive cubic though, but it's faster and uses less material.

Lightning is usually my go to for non functional parts.

Way lower print times and filament use.

For functional parts I usually use gyroid, adaptive cubic, 3D hexagon or one of the other I fills that puts filament in many directions in three axes. unless the stress points are very obvious, and then I sometimes eyeball basic bracing and add it with my (very) limited CAD skills.

What the AI slop did I just read? That wasn't even edited.

The infill selections for comparison don't make a lick of sense, and one of the tables doesn't even have content that matches its introduction.

What a waste of time.

Edit: 57 upvotes? What the hell. Does nobody read the article?
