- A new 3D printed material is making a move. Scientists have embedded tiny particles of magnetic iron into a silicon rubber to create a substance that can be 'programmed' by a magnetic field. By 3D printing this into any shape, the researchers can use a computer model to generate a wide range of fast movements. With potential uses in soft robotics, engineering and medicine, this is an exciting new addition to the field of transformable materials.

1:35, there are no magnetic charges. Magnetic fields are Dipole only, and only come from electric current
Thank you for spotting that lethiac. That should indeed be ‘field’ rather than ‘charge’.
That's why they should teach physics at school! lol
Y Qisq um....
They do.
Magnetic monopoles might have created
That's funny, today I watched a video saying that according to quantum physics, monopole magnets could be made. (In theory... Just like electric charges can be isolated.)
But I don't think it has been created yet, due to some "technical challenges".
the fact that this is simple, highly understood, 3D-printable, and high controllability, i see much potential
the last variable is scalable
It is not simple, it needs an out side magnetic field controller that probably bigger and more complex.
everybody gangsta til the plastic starts wiggling
time to print myself my own pulsating fleshlight
And then there are THOSE kinds of people
😂😂😂😂
Rule 34, if it exists there is porn of it
I like your thinking!! XD
This is freaking me out a lot more than I anticipated.
I don't like how only material was shown, what about the whole controller, that makes the material move the way it does? Is it not shown because this isn't real, or is it not shown because that's the drawback of technology? Even if material itself can move, etc. to control it properly, you need precise field creation, also what about the inverse square law? What is the range on this material per Tesla of magnetic flux?
This is so futuristic but the video kinda seems like it was made in the late 90s, something I might’ve watched at school. Incredibly cool none the less
Thanks. I'll add magnets and silicone to my list of deepest fears and doomsday prep now 😂
I want to see where the magnets are.
Need to see if this can be used to create artificial muscles & tendons to be embedded in 3d printed hand
I literally thought in the same thing when i saw this material
Prosthetic limbs could be revolutionary
Were all of these movements done purely by turning on and off a magnetic field, or multiple? Could these ever be more precisely controlled with irregular currents?
I want one of the little snowflake ones to roll me tiny stuff adorably
كه له ك جانه😍😍
First ideal commercial application: Novelty Rubber Spiders =)
Where can we buy this material for 3d printer?
You still have to apply an outside magnetic field, nothing internal with batteries is yet possible, right?
Medhusalem well that’s not it’s purpose. You could use pneumatics like they do on artificial muscles.
But implantable cardioverter-defibrillator (ICD) has batteries...
that would depend on the flux sensitivity of the material as well as how powerful a battery. MRI/FMRI would be early ideal
Any nonreversible motion costs energy, and it has to come from somewhere, be it an external magnetic field, or electric current, or heat gradient, or light or something.
Batteries inside would be too cumbersome for certain applications, and an external source would be useful.
I want a cute mini thing that can swim
So this material has a negative poisson ratio?
Ok nice. Where can I buy it since it already exists for 3d printers?
This is pretty creepy for me but would like to see it!
Where can I buy the 3D printer and material
Material can be probably made as a custom order from any manufacturer, since it's just silicon and ferrous material. If this article is real, then 3D printer works with custom made software for controlling the polarisation of deposited material, unless they make software available / someone copies it, I don't think this will be for home use.
So and where to buy?
I wonder if these could replases injured muscle?
Flexible synthetic muscle strands for bipedal robots!
better bring magnet every day in case of an invasion
I could see this being using in infrastructure uses. Having something that would suddenly change shape to maybe collapse in a certain way, or catch Debris.
...OR....be the T1000!!
ohhhh , i see. science is so amazing
It looks like the fortune telling fish's cousin XD
make a tiny origami person that can walk and has hands, have ai from Boston robots navigate it, use MRI to generate a image/ path so the robots can just walk through your body and repair it like ship building. Hell have the person controlled via AR/VR and now a doctor is walking around your body. Another idea, have a tiny camera and light on it that's powered by the magnetic field for sight.
OK but what are they calling it? They must have a name four this new innovative feature.
That's cool.
Make artificial muscles already!
awesome
How big a magnet does this need, though?
Karl Kastor Powerful enough to move iron at a distance. So big, and exponentially bigger as you get further away.
Answer is dependent of mass of specimen you wish to move and type of movement.
The future is now, old man!
Sweet
This reminds me of Spiderman's suit somehow...
Gallifrox or back to the futur clothes
A really small step for nanorobots?
I don't understand the red light thing at all. Maybe it is to hide the strings :-)
Science is beautiful beyond description.
Time and evolution gave us a brain capable of creating materials with properties that can’t be made or found in nature.
Isn’t that sensational?
1 step closer to 3D printed heart transplants.
Okay, but *who* created the material, *where* are they located, and *how* am I supposed to throw money in their direction if I don't know their direction?
That's the problem with PopSci, they half ass their research. The article itself doesn't mention who either, just that it's happening.
The link to the paper is in the description AND at the end of the video...
James Whitehead I was talking about the article linked. It cited it's sources, but these sources don't say where these things happen.
The linked paper includes information about all the contributing authors - you can either hover over or click on each name and it will tell you the institution they are from or where the work was done, or you can click on the 'author information' section on the right hand side of the page and it also tells you all the affiliations.
Soft Active Materials Laboratory, Department of Mechanical Engineering, Massachusetts Institute of Technology, Cambridge, MA, USA
Yoonho Kim, Hyunwoo Yuk, Ruike Zhao & Xuanhe Zhao
Harvard-MIT Division of Health Sciences and Technology, Massachusetts Institute of Technology, Cambridge, MA, USA
Yoonho Kim
Department of Mechanical and Industrial Engineering, New Jersey Institute of Technology, Newark, NJ, USA
Shawn A. Chester

Xuanhe Zhao
So this work was done at MIT in the states.
You can also check the 'acknowledgements' tab which might include any other institutions that took part in the paper. In this case:
This work is supported by the National Science Foundation (CMMI-1661627) and the Office of Naval Research (N00014-17-1-2920) and the MIT Institute for Soldier Nanotechnologies. Y.K. acknowledges financial support from Harvard-MIT Division of Health Sciences and Technology. H.Y. acknowledges financial support from a Samsung Scholarship.
So maybe some of the work came from the Naval Research base.
You can also contact the authors using the links in the paper if you want to find out more.
James Whitehead I appreciate that greatly! I'm on a phone, I can't hover. I'll look into these places. 😃
а чому не закладати дріт між простірами, як робили з рідкими магнітами, прі подачи струму возніка магнітна індукція, яка заставляж рухати? таким чином вам треба подати імпульс, як мишцах людини
thats cool af
Лайк однозначно!
Amazing!!
Its alive
kewl
Imagine making a house out of this material (or something similar), so you can see the house kind of building it self.
You would need to keep magnetic field same at all times for the house to keep it shape.
Hmm I think if these are made in a nano scale, it could lift heavy stuff. It's like an electronic muscle
Too bad it's limited to non-magnetic materials.
I can't swallow tablets!
Ok, just swallow this rolled up newspaper then!
i would not call it smart material, it's a plastic/silicate material with magnetized infill which gives it movable properties when introduced to an electrical current or other material with magnetic properties. it's really old science
Listing drawbacks of other materials and then only succeeding in eliminating one of them is a weird way of advertising. Yes, it's fast. But it still has limited range of motion and it needs to be connected to a huge electromagnetic field generator.
Don't get me wrong, this is an amazing technology. But don't do the tv commercial thing with grey filter and lower res videos talking trash about other products. Be forthright and show us where you started, where you are now and what challenges you are still facing! Science is about constant development, you don't have to hide that! Wear it proudly!
I know this is just a random youtube channel showcasing a video but maybe someone from the company will read this and wake the boomers up...
Synthetic muscle enough said lol
This disturbs me.
Imagine what this technology could do for the sex toy industry. That's how you pay your R&D
Engage Rule 34
Go fold abnormal protein In ALS if you can get the medication to the proteins cells
SILICONE not SILICON !!
WTF!!!
Bruh that snowflake is grooving
Omfg
Its creepy
Imagine snowflake shaped robots destroying the earth 😂
condoms?
