Truly the answer is always gyroid. It's near the top in every category, print speed, strength, strength to weight, anisotropy. You basically shouldn't ever print with anything else unless you have a niche usecase or an aesthetic reason to show the infill
It’s honestly very specific to the type and direction of force you are using, it’s honestly difficult to test all the styles of infills in real practical conditions, generally this sort of loading test is done longitudinal or parallel to the direction of the grain, causing pure tensional deformation. If I design a particular with a complex topology the forces would depend on the way the part is used. That’s when we use a FEA analysis. Still great stuff for generic hobby prints
Gyroid is great but it does introduce varying layer times which can sometimes show up as a pattern of lines on the outside of a smooth wall type print. Personally I'm a fan of cubic and a adaptive cubic
Stress builds up on the outside surface of an object so it makes sense that more wall thickness = stronger pieces. That’s also the reason i beams have so much material on the top and bottom and a thin part connecting them to stop sheer stress that is relatively week compared to the compression and tension os f the rest
Great analysis! Would like to know about absolute strength vs strength to weight ratio. I tend to not be building an airplane and a few extra grams is okay for most of what I do.
@@ufffd THat's not really the point. The point is, infill percent being constant, which pattern produces the most strength. Basically the test he did, but I don't care about the result divided by weight. Just the result.
Yeah, I wouldn't expect the Hilbert Curve infill to do well in terms of strength. It's got very interesting properties like continuity in the limit, but those properties also make it very bad at being a material. Large amounts of right angles, gonna have relatively few crossing points with the walls where it can share its stress... Way better to just watch those curves from afar.
Lightning may have a better strength to weight ratio in this test, but when you're pressing on it from all sides there's a definite discrepancy, especially on larger parts 👀
I think in the full video, he mentioned that the lighting infill is very light, which results in a high strength-to-weight ratio because the wall remains only one layer thick.
And not to mention the shape of the print plays a part in lightning infil. In a box shape with flat sides all around it probably does better then the majority of prints printed with odd shapes and curves
Lightning only has the highest strength to weight ratio because it has the lowest weight and medium strength. Gyroid is better because it has a very high strength and lower weight than other infill patterns.
No way bro pulled up a spreadsheet instead of showing the best to worst prints 😂. I’m an engineer (*cough* in training *cough*) and even I know not to show the general public a spreadsheet to display my results 😂
Great content as usual, Hikaru! And to the editor, where can I find the full playlist for this video? There are couple of songs that I really like, 24:00 or th one at 12:40 , Thanks.
Triangles. Any type of 3D infill is bad. Triangles with double infill multiplayer from cura at around 15% and the prints are lightweight and extremely strong
Really glad you took the time to show us examples of the patterns

I need to start using it, that’s for the tip
Gyroid for the win!
I saw someone talking about higher printer wear because of the wiggly uneven pattern. Is there anything to that?
Or a slicer that doesn’t support it.
@@crimsondragon2677 you can use whatever slicer you like tho and still export for your printer
Hexagons are the bestagons
Gyroid is the betteroid
YESSIRRRR MY BROTHER PREACH
CCPGREY HOMIE
A scientist debunked it. Triangles are the bestangles.
@UriahStuff triangles are the strongest, and hexagons are made of them, but the ratio of space to strength goes to the hexagon hands down
Hexagon shape is the stonges because Hexagons are the Bestergones ❤

Gyroid is GOAT
this is crazy underrated ! thanks for the info
Well the video did recently upload, he may still end up getting plenty of views.

I thought we already determined that nuclear pasta is our structural integrity overlord

if the only thing that matters is strength you should always do 99% infill
@@ufffd THat's not really the point. The point is, infill percent being constant, which pattern produces the most strength. Basically the test he did, but I don't care about the result divided by weight. Just the result.
I use gyroid with 10% infill for most stuff I use.
(biggest force on them isn't more than 1kg)
Excelent tests! Thanks a lot for sharing... I still think that the shape of the printed piece can modify the effect of the infill, but it helps a lot
Well I am impressed with lightning
Oh damn. Actually some good test results !
Holy moly what a video so much data thank you!

Didn't know tri-hexoganal was actually good. Been using that for all my prints because it looks good on the print bed lol
Based on these results it was apparently one of the worst.

Hey, how about you test their compressile strength next?
Great goddamn vid
Gyroid and cubic are the only options. Also btw most strength comes from the walls
Grid, Cubic and Gyroid.
Thank you for the video.
Did you test the same with impact and presure instead of pulling force that bends the material?
1 percent line infill all the way
Lightning only has the highest strength to weight ratio because it has the lowest weight and medium strength. Gyroid is better because it has a very high strength and lower weight than other infill patterns.
Nice vid
I've heard from other studies that Grid is the strongest.

Doesn’t lighting strength depend on the orientation you apply the force?
I was gonna say I know Boeing uses honeycomb structures in their satellites, lightweight and extremely strong.
So did you find a infill percentage and infill pattern that worked the best. Looks like Gyroid passed the honeycomb.
Thank you!
3d honeycomb of course
Great content as usual, Hikaru!
And to the editor,
where can I find the full playlist for this video?
There are couple of songs that I really like,
24:00 or th one at 12:40 , Thanks.
What 3d printer software are you using?
Ultimaker Cura, I'm pretty sure
Thanks
Do you know if its for free
@@designing-n-creating-3d-models it is! I use it and it's amazing
@@designing-n-creating-3d-models you can't use it for modeling itself but blender does that.
So now, the best s/w ratio is lightning infill at 20%, with 3 walls
How many trials are you running for each variable change?
i think we all know the answer to this
Ah yes, the age old question; Does density increase strength? Pretty sure we already know that one, bud.
it was obvious, gyroid has the biggest surface, meaning most material technically so yea
I think CNC Kitchen made a similar test series
I got that exact same thermostat
Triangles. Any type of 3D infill is bad. Triangles with double infill multiplayer from cura at around 15% and the prints are lightweight and extremely strong
what's the sample size for each version? higher sample size is much more important than stuff like a climate controlled room
but when lightning, the 3d print is almost empty?
Honeycomb, nothing more needs to be said
The more ductile mean more stretchy without breaking right?
I'm sure he graduated college bc of this
Why was Lightning that strong?
If its plastic when would I ever care about weight?
100% is the strongest
Lighting is the best is kinda shocking
Gyroid the best
ductile, or plastic
Using a larger nozzle size will help
0 infill
gyroid on top
gyroid.
full fill.

????????
Hexagon is the bestagon
