Translation: They built a plastic thing that can take a lot of stress, which they think would be cooler if it were made of graphene, so they put graphene in the headline to ride its hype.
Great ! thanks for your translation :)
Doug Johnson you just bullied MIT to change their title on a video and it worked
"bullied"
They found a way to arrange flakes of Graphene into a 3D structure without losing its properties. For now Graphene is only practical in a 2D application. Stacking them in layers would make it just as dense as any other carbon block, which would make it no different than any other lump of diamond. So arranging bits of Graphene this way would make the structure porous and lightweight, without sacrificing the material strength. But the structure can also be made using other conventional materials.
big bruh moment.
It seems graphene could also be used for clickbait

Dis comment, tho.
well then check hydraulicpresschannel

I don't understand. First, it's a 3D material using graphene right? Then it was tested with plastic? Conclusion is: geometries can change various aspects of material.
But... where is the graphene part come into this? Other than that one 3D simulation which was ... on a microscopic scale rather than real life scale like these materials, judging by the hexagonal surfaces.
Glad I'm not the only one confused by the structure of this video
sphinxrave I think that they are talking about applying the shape of graphene to non-graphene materials in order to obtain higher strength, because graphene is strong because of the geometric arrangement of its atoms? This point is stated at 1:23. However, I'm pretty confused too. Gyroids aren't new, if Wikipedia is to be trusted. Apparently, it has been used experimentally for some time now due to its unique geometric properties. It appears that these MIT guys are saying that the shape is also mechanically very strong, besides its other characteristics, which are already known.
The only thing that would make sense to me (but it's not at all what they _said_ in this video) is that they made graphite in gyroid-shape, rather than sheets, to make it a super strong but 3 dimensional structure.
The language used was just plain confusing. They successfully designed New 3-D Material (presumably using graphene). Analyzing atomic interactions produced mathematical framework for simulating an experiment. Here graphics show a simulated crumpling "experiment simulation" and "actual experiment setup", except the graphene is irrelevant now somehow, since actual experiment setup is now using plastic.... To test their material (which, is graphene? no? ), they printed 3d models (using plastic) ... ???
It seems the team started off from graphene and concluded that geometry > graphene. And from the article: The team used 3-D-printed models of the structure, enlarged to thousands of times their natural size, for testing purposes.
I welcome anyone to change my mind, but I feel like comparing atomic simulations on graphene flakes in a gyroid vs experimentation on macro objects several thousands times bigger (more like millions) is not highly applicable, and like +Tiles Murphy said, it can be a mechanical property, but then I think the graphene part of this article/video becomes academic click-bait.
I think you might be expecting too much about the graphene connection in this video. I agree it is confusing, but I rewatched the first 30 seconds a few times and the transition point is at about 0:19. The way I read that section is this "Graphene, in 2D, is one of the strongest materials known, but it's hard trying to replicate that strength in 3D. Here's a new 3D material that's 10x stronger than steel" Basically they're focusing on merely building strong materials, they're not concerned with graphene except for its strength.
Hello i'm MIT and welcome to the hidraulic press channel
Literally got clickbated by MIT…you gotta be fucking kidding me… instead of actually talking about graphene, which is what you're title suggests, instead you talk about the geometric feature it was designed in. Thats great that this new shape is exactly strong, but its still misleading
"10x stronger than steal"
*uses steal plates to test durability
There are so many things you got wrong and im not explaining everything, unless you were joking.
@Raita Xross if you don’t want to explain why did you bother responding
for those of you who don't understand the graphene connection, here's an extract from a website "Now, a team of MIT researchers discovered that taking small flakes of graphene and fusing them following a mesh-like structure not only retains the material’s strength, but the graphene also remains porous."
im usually quite good with these videos but this one is leaving me a bit 'huuuuuh' ?
strength of a material isn’t dictated by how much is used but by the geometry. Take trusses for example
I demand this structure as an infill setting in Cura, it would be really cool
Please get this comment viral till they add this as an option.
@@mohammadabboud it already was an option at the time you made this comment
Even though this is posed against steel, it would be interesting to see how this structure would perform with steel.
True
Also nice for being the only comment here not from 5 years ago. Hello fellow person from this time 👋 And happy New Year later today depending on where you are! ❇🥂 (couldn't find the party hat and firework emojis 😔) I guess as they say in these comments sometimes. greetings from Florida
what's this "strongest, lightest materials known" though? they said they were making that structure out of commercial plastic.
Lucian Leesonja They also said "...graphene is thought to be the strongest of all known materials." I guess they haven't given a name to the experimental 3D material they made.
and that's news to who?
Lucian Leesonja: It's just a scale model, just like Derik Zoolander's "School for Kids Who Can't Read Good and Want to Do Other Stuff Good Too" isn't actually a school for ants.
It's a plastic model built for evaluating the gyroid structure, to see if that is what graphene can be feasibly molded into.
materials and 3D structures are not interchangeable
"This contorted plastic cube may attack at any time, so we must deal with it!"
What are the exact strength characteristics, and can you provide the 3d model or equations to generate the shape somewhere?
I am passionately wondering if this could be applied to shipbuilding and be used to build an unsinkable ship hull.
Hmm perhaps this could be used in military armor. Also in planes and rockets.
Hi.
is there any way for you guys to share the stl for that gyroid?
I'd love to look into it myself. thank you
Where are the stl files so I can 3D print this?
Two years later and this pattern is a standard infil in Cura. Science is cool!
The 3d material in this case was a plastic, not graphene. It was a experiment to examine exotic geometry in general, perhaps applicable to materials other than graphene.
how does this graphine composite react to temperature changes?
This is terrifying. Usually with slower deformation...you can start to see signs of failure before it actually happens. With their "new" stuff....you won't know it's failed until it literally explodes. Imagine a buildings support column...just explodes. Literally not shit you can do to stop it then. With slower deformation...you will see the column starting to crack/crumble before it actually completely fails. I guess it could have its uses...but I damn sure wouldn't use it on things like airplanes, buildings, etc.
Could you publish a 3D printing file for the structure?
Material with a lot less size of 'cells' or 'microcells' would have other properties at all. But it couldn't be made by means of contemporary 3D-printers, need somewhat complicated technology. For instance, you can weave such multilayered structure of heat expanded material threads, kinda yeast, fill it with graphene compound, then heat it and you're gonna get porous material with stretched and oriented thin graphene layers.
but can anyone explain what happens to the structure if the length of the material is increased? does it behave in the same manner?
The aim seems to be to build (3D print) graphene layer by layer in atomic scale and design yield strength by choice of structure model. Associate this to designed dislocations, if there is such a thing. This implies extraordinary macro level properties - as stated in the heading. Will be very interesting to follow.
Somewhat terrifying
Can someone provide the mathematical model of the shape? please...
Things this is missing:
graphene
how much force it took
anything other than a compressive force test (tension, shear, etc.)
something useful made out of it
so can we make an armor out of this material? what is the weight difference?
Is there a way I could maybe get this design in via .stl file? I would like to 3d print my own copy.
Adjusting geometry and thickness changes the mechanical properties of the material! Amazing, maybe this Wikipedia article will further advance your research.
Honeycomb structure
en.wikipedia.org/wiki/Honeycomb_structure
Honeycomb structures are natural or man-made structures that have the geometry of a honeycomb to allow the minimization of the amount of used material to reach minimal weight and minimal material cost. The geometry of honeycomb structures can vary widely but the common feature of all such structures is an array of hollow cells formed between thin vertical walls. The cells are often columnar and hexagonal in shape. A honeycomb shaped structure provides a material with minimal density and relative high out-of-plane compression properties and out-of-plane shear properties.[1]
the way you arrange a shape gives you different results.
Thank you M.I.T.

People new that thousands of years ago, history channel talk about ancient technology, how ancient civilizations build some walls that are still standing, not even earthquakes could bring them down, the outcome of the discovery was the strength of the walls, a nd building wasn't due to the material it was made of, but a material item strength came from its geometrical design allowing the walls to be undistructable by wind, floods,earthquakes, scientists are barely discoving what ancient civilizations knew.
Print a standard I beam used in commercial construction from this material and test it next to a hot rolled steel I beam and put it through some tests. I want to see the results.
Can i get the stl to print it?
Use this geometry principal (tons of surface area per volume) for the anode & cathode of an electrolytic cell...see what happens.
Sure wish they had a compression gauge readout for both samples. Bet the thinner walled sample didn't reach nearly the same max load as the thicker one.
Graphene is the material "the matter from which a thing is or can be made." The structure is not a material. You have one of the strongest lightweight material structures known.
Once the material begins to collapse, the geometry changes, does it not? It seems intuitively to me that once this material begins to collapse, it will collapse exponentially. But as it breaks up and the pieces twist around, it maintains it's strength.
le graphène est très élastique alors la forme change beaucoup, mais j'imagine qu'ils ont utilisé un plastique qui a les mêmes propriétés, à une fraction de la force.
mais avec une porosité d'environ 85% les morceaux cassés ne changent pas grand chose.
I think that you mean the "shape" changes by collapsing, molecular geometry is not affected.
I'm not familiar with chemistry, but I think you might be right. I thought it was implied by the video that it was the physical shape of the material that made it stronger.
The video is so confusing and misleading that I already labeled it as "waste of energy" and won't even attempt to clarify it to myself:) But just to finish what I started: Yes, you are right, they also imply that the physical shape has effects on the stability of object. I merely commented to point out that there is also sth called molecular geometry and it is different than the aforementioned shape. Cheers..
We need bumpers made from that stuff
Very similar to the structure of the bones.
So this is the plastic Trask Sentinels are made of.
"This series of sentinels is made of plastics, not metals."
looks like good research for 3D printed infill.
Lightweight baby
Light weighting is it! DARPA-e has recognized light weighting as a key challenge for massively reducing fuel use in transportation.
how could it be used in energy storage?
That test is only for gradual pressure, they need to test both with instant high impact.
An atom is a 3 dimensional object since you could measure it in 3 dimensions, well if you could see it. So therefore an object made of 3 dimensional objects like graphene would be a 3 dimensional object. Just because you can't see it's 3rd dimension doesn't mean it's not there. The fact alone that you see 2 dimensions means the 3rd must also exist in order to give substance to the other 2.
I like the way graphene is not shown
It seems like you could make a fractal structure with that same pattern on ever smaller scales.
This is not material. It is SHAPE
Mass producing graphene will require universities. Specifically, and hopefully, MIT
Wow! Different geometries break at different amount of applied forces... Who would have thought that? Are they able to calculate the tensions inside the material? Maybe MIT should do more IT and leave this stuff to others...
If put in motor cycle gloves which one would last longest sliding wise I wouldn't think there would be Massive pressure on it so the thicker material would last longer in a slide
I think the point was that graphene would be the lightest thing that would also allow for materials to be made with this more optimal structure? But the video's really just about the structure
Hydraulic press envy
You say it's a strong material, however, judging from the test it behaves more like ceramics (no plasticity). So this material a replacement for steel or something more on the brittle materials side?
The interesting aspect is, how long before they realized that the key element wasn't the graphene?
Then what was it?
How can I buy that ?
That material will use to heli carriers or spacecrafts to fly high or go to space without feeling heavyweight.
That press machine are strong than any material composition on this world. Lol!
Curious if they tried a honeycomb pattern in 3D with this material
Pssst. They're actually building a Terminator and just testing out the exo skeleton material.
Ma perchè non avete messo la forza che esercitava quella pressa?
intro music ID ?
Seems like many in the comments are confused with the structure of this video. I am a bit confused as well, but I suppose what they actually meant is that we can shape the 2d graphene surface in the way similar to that piece of plastic in the video.
*My question is:* the structure shown in the video does not seems to be homeomorphic to a surface. Or maybe it's the graphene's structure that allows us to make things that are not homeomorphic to a planar object? Can anyone give me the actual journal paper of that? (sorry if my question is too obvious, my knowledge in topology is very superficial, maybe there is some property of the surface of non-simply connected figures that I don't know)
I love how they used something that is popular in social media right now (hydraulic press) and turned into a great science video. Very well done!
I identify with the block on the right. I can take a lot of crap for a long time. But when it comes time for me to bust, watch out, man.
Cool!!!
so they are essentially making plastic cardboard with a fancier matrix. what is the graphene connection?
The video is confusing but im hoping that they will succeed to develop that material completely. But it must be enviromentaly friendly and low cost so it could replace aluminum or carbon fiber for car and airplane
How much force was applied by the press?
comentator not much. In this video they haven't test the new material. This pink part was a macro scale model of meta material they are working on. Those parts were made with ordinary plastic. They meant to represent how different meta properties can influence the behaviour of the material under stress. In the video they said that materials can be made using this principle however they have not shown any materials or parts made using this principle.
That makes little sense, but how does the meta property of thickness even translate over to graphene?
sphinxrave that was the point of this video
Rafal Lasocki it is? But how would thickness meta property apply to a 2D graphene structure. Or how a atomic simulation of graphene can be used to approximate graphene flakes which won't be perfectly continuous or uniform? I'm open to learning more about the research, but this delivery needs more work.
sphinxrave you are asking all the right questions. Imagine how material with such properties would change the World. 20 times lighter than steel and 1000 times stronger
This research is potentially worth billions and it is unlikely they would give away any crucial details. For now we must also assume this is only an idea and only tested by computer simulations.
(Edit: grammar)
Is there a word/name for this shape/pattern?
Where is the graphene? You know, even then scientists in the UK that discovered graphene, they didn't do a glistzy video to promote their work, they just humbly released it to the scientific community. Some universities produce great work but don't have the budget for these videos. At least use the budget to promote the better research you do.
Make a full size catapult that can be pulled by their cheetah, could take over Canada with it :0
great!
So the pink thing inside the press is obviously a plastic printed part, bue they said it can be stronger when the geometry changes.... But what does it have to do with graphene being hard to create in 3d form?
Welcome to the Hydraulic Press Channel
marter1234 gaming yes....
Re-inventing the bone wheel.
This video inaccurately reports on the finding. At 0:42, the narrator suggests that the "new material" was tested using 3d-printed plastic models, while in fact, it is the geometrical configuration that was tested, and found to be very strong, regardless of material. This distinction is a key point of the story.
From the article:
"The new findings show that the crucial aspect of the new 3-D forms has more to do with their unusual geometrical configuration than with the material itself, which suggests that similar strong, lightweight materials could be made from a variety of materials by creating similar geometric features."
if they could somehow converted the graphene into a strong viable 3d structure, imagine the possibility it could give to the future of engineering. to add to those spectacular prospect, let say in the immediate future we could made an easily essembled giant 3D printer, we could create an entire highly durable sky scrapper without using any actual human labour. another nail to the coffin for future of blue collar indudtry. automation IS INEVITABLE
1M of views on a couple of months... it makes me believe, once again, on humanity...
how much force did they apply?
5000 tons
Is this available at cheapest price?
Why this colour?
Great, how long until transparent aluminum.
do it again do it again : D
Dammit Mit youtube channel, i love you
Marcos G fr
True!
*_Sooo.., basically this is the real life substitute for "Vibranium"? [Strongest+Lightest]_*
how about their melting point?
But why in that color?
they should have atleast explained their difference in ductile and brittle deformation instead of just calling it deformation. i mean i know its made out of plastic ; therefore plastic - ductile deformation but reacts a brittle deformation at treshold compressive stress
My next infill for 3d printer projects
Trigger warning from 1:14 to 1:22.

I didn't get the joke
one is thicc and the other isnt
You're too hot for those kinds of jokes.
LOLOLOL!!! Good one, BROH! You should post something about triggered SJWs or your other political beliefs in the comment section of EVERY UA-cam VIDEO!! LOLOLOLOL!!! U R SOOOO SMRT!!!
Magnesium nano particle alloy is top ranked.
What's the lifespan of this material
If they only had to add Graphene into the material. Them they would have discovered something ;) GREAT.
At 20 seconds you will see the B Roll footage that was decided upon to best create a visualization for these “MIT researchers breakthrough” which amounts to a couple meatheads pushing on a 3d model like chimpanzees. Sometimes I just love being human.
