I got to speak with the team behind MettleWood, a revolutionary material stronger than steel and made entirely from wood, at the White House Demo Day organized by the Office of Science and Technology Policy (OSTP). We explore InventWood’s high-pressure densification process and applications from structural beams to honeycomb panels. This could be a game-changer for sustainable building materials!

Ignore people making this about politics. The important thing is seeing cool new tech and manufacturing returning to the US!
Its always nice to see that there are news sources our there that actually try and look at things from several angles
it was brave of you to put out a video involving the current admin... I'm no fan of them, but just like you said, I would have went too. and that says A LOT coming from me,... let's just say that "I'm no fan of the current admin" is putting it lightly... very Very VERY LIGHTLY!!! lol But I'm the type of person that WILL give CREDIT, WHERE CREDIT IS DUE. And I think the CHIPS Act is a GREAT START (but frankly it's not enough TBH) ...
But I have to add that it was also brave of you to bring up all of the 'controversy' that the video caused.... BUT if people are serious about tech and the future then it won't matter what is going on in capitol hilll :)
Keep the good and leave the bad man. Great video as always.
If I no longer find my interest I would just go somewhere else.
People are so entitled nowadays, some only comment when they're unsatisfied.
Focus on the nice stuff for the greater good. Take care
"Any species" so what about iron wood?
Wait a second - thats the process NileRed used for his bulletproof wood video
Yep! His video was actually based on their research work. Also his transparent wood video! It's super cool stuff.
you think nile red was the first person to come up with that process? 😂lmao no, I love nile red but scientists have been working on this for years. First time i heard about it was in 2018 but im sure the technology was being worked on before that. Regardless, we need more of this, maybe it'l force the companies making this stuff to start massive tree farms which i see as an absolute win even if those trees are destined to be cut, just because it'l still probably be less destructive than manufacturing steel lel
First thing that came to my mind too lol.
Yes, it is. He based his off of a paper published in Nature in 2018. Guessing this company did the same or similar.
@@Munden I wonder if they started after seeing niles red video?
Can you imagine the poor termite that runs up on a piece of that and breaks all his teeth out! 🤣
WINNER!!! lmao
❤
no the termite would go "OH MY GOD THERE SO MUCH
Unfortunately termites will be fine with it :/
We had a mice problem: they've been eating through damn concrete! Had to mix in a bit of broken glass into it as a deterrent. They don't like to cut their mouth.
Termites aren't that smart.
So they say "stronger than steel", and I found they quote an 85,000 psi tensile strength value and say "50% stronger than steel" which means they are probably comparing to A36 steel (which is really crappy steel). Most alloys of aluminum are stronger than steel if we are using A36. I'd be curious to see what the tensile modulus is. Strength isn't everything with structures. You can have a strong material but if its is soft, your building is going to have quite a bit of unpleasant sway. Something else is buckling. Buckling is a stiffness, not strength, driven phenomenon.
A36 is structural steel, so it is a fair comparison. The other common structural steel is A572, which is the typical steel used for I-beams.
Stiffness of a column scales linearly with EI (young's modulus * polar moment of inertia). I found poplar to have a young's modulus of 8.8 GPa, if we compress it by a factor of 5 along only one axis (easier to do, but not optimal for maximum performance), we get a young's modulus of ~44GPa, about 1/5th that of A36 steel. From this we would find that you have about 1/5th the ability to resist buckling in a column. This is using the properties of an isotropic material, but this material is orthotropic, so the equations may change a little; however, I would be surprised to find something that far from a linear scaling in E. Hopefully this helps on the buckling front. I agree that sway and joining sections may be a bit more challenging. Finally, I think that wood may be better at attenuating some vibrations than steel.
@@pabloarroyo8546 I'm not arguing, but I think turning the 5x compression I to a 5x GPa radically underestimates the non-linear strengthening of the wood fibers that comes from the massive increase in contact with the lignin.
Yall guys are missing the point. I bet you would take a house built with this over the current stick built market.
From what I remember, normal hardwood wood can already be about 20% stronger than structural steel in compression. And when it is in compression, it's tension strength is also amplified. What they are doing here is 'pre-compressing' the wood, but I am skeptical of it being comparable to actual wood in compression.
Honestly I hope the guy you interviewed is right about wood making a comeback. I'm so fucking tired of the bland concrete, glass, and brushed aluminum/stainless cubes look of postmodern architecture. Engineered wood composites are cool as fuck.
Give it to PC components like Fractal's North... they knows what's the it
This product is based off a university of Maryland research they reduce the lant by 45% heated and compress it the science is legit
Right on.If funky curvy glu-lam structures and hydraulic presses could have babies... !
Scotty, dont let the haters get to you. I understood why you made the other video and thank you for it. Hope your health is better bud. Side effects from concusions can take years to resolve if ever. You keep doing you and your core audience will be here. Peace Sir.
Recently, I've found comfort in listening to Silvie at The Concussion Community podcast even though I haven't signed up for her program. Thanks for being here. 🖖
Hey man, don’t make excuses for this Whitehouse visit. Thank you to taking all us with you, it was interesting and it was not politics.
You assume a lot. And are wrong.
Don't let the haters deter you. You have a worthy reputation for sharing unbiased info and educating people about how the world of manufacturing works. Keep discovering and being curious.
There's a local company called Swiss Wood Solutions that has been doing something similar for a few years. They have a bit of a different focus for applications, but it's a very interesting product. They also have some for musical instruments, replacing exotic hardwoods with engineered local FSC wood.
Don't sweat the haters man. Engineering is intersectional. Thanks for bringing us this awesome coverage.
Yeah and a ton of his audience is not intersectional with American government because they aren't American? Also people are free not to care about government even if they are American.
@@deadlock_problemit’s a global company.
@@deadlock_problemhow did you come to that conclusion?
I'm really glad you attended the WH event, and EVEN more glad that you kept the video up and replied to bashing. You are 100% right that policies have massive impacts in the tech hobby and industry. And if people just stick their fingers in their ears and shout out the "Bleh! Politics!" they'll just end up in a stagnant or backsliding economy, where it's impossible to stay on the cutting edge. I'm glad you used your platform to remind us that politics isn't parties; it's policies. And we need policies that make more Silicon Valleys and less Mississippis.
Honey, i shrunk the deck.
I think this is the first time I've seen this movie referenced in over a decade... We're getting old!

galvanized square steel and eco-friendly wood veneers
it was my first thought when I saw the thumbnail 😂😂
Bahagahahaha😂
Held together with screws borrowed from aunt
Idk I can still see an application for this densified wood. Especially if aesthetics are concerned, doing the veneered steel requires substantially more labor and skill for installation.
If anything, I think it's an interesting approach to materials
I wonder what the corrosion properties are? Do you need to seal it for outdoor use, etc. What a fantastic idea!
Nilered did a video on the process of densifying wood, making 'bulletproof' wood. It's a fantastic video.
I was going to comment this! Such a cool video.
Yep! His video was actually based on their research work. Also his transparent wood video! It's super cool stuff.
Densifying wood is not really a new idea, i did labsests of it during ground school in the 90's. But it has never been commercialized and utilized to it's full potential. As seen in this video, you can do absolutely mindbreaking stuff with this. You could probably even build rickets with this stuff since it's self extinguishing and just charifies it's surface which will then be inpenetrable by heat and flames.
the 3D pressing is amazing, wood cars again!
I love this guy ❤️
Just because people work at something you don't like, doesn't mean they are smart, cleaver, nice, and wholesome people. As long as you make videos that can educate us I'm happy
👍👍👍 In the late 70's there was a Canadian TV series called Science International with Tilu Leek and Joseph Campanella. One of the segments profiled a Japanase R&D company that turned cheap fast growing soft wood (entire 20-30 foot tree trunks); used industrial strength microwave to "cook it" (like a baked potato) then compressed it with an industrial hydraulic press to concentrate the density and remove moisture. Out came a very dense, dimensionally stable piece of beam lumber, with the strength of steel and all the curves / bends / imperfections removed. I often wondered about the tech and why it never developed further since then. I surmised the cost of the process was a detrimental factor. Good to see it progressing at a trade show in your video. 🤩👍
I'm glad to hear that they are able to produce wood now and levels that are much higher tolerances and strength.That's reall be cool.Maybe more innovation.Then a new field's with new material
You know when a country is fucked when you feel like you need to do a video about people getting mad when you visit the government office. Don't ever stop and keep being you!
Some cult members get extra sad if you deal with reality.
How do you mean?
I dont' care about whatever the American government has to say about anything. I'm not American.
@@deadlock_problem sadly the stupidity from it does spread, and most decisions it makes do impact the world. But the point is about people getting butt hurt for talking to “the other side”.
@@SimJDKS I barely care about my countries politics I care even less about politics of other countries. I would be wasting most of my spare time if I kept up with every random countries politics.
The other side thing is a leap of logic and gaslighting. Americans only make a large minority of youtube watcher.
You have the best attitude. Please stay this way.
Spitfires had propellers made from compressed wood in WW2.
You can also do the honeycomb with cardboard and it will support your weight
the honeycomb is a cheapout technique for companies
And that will be a regular IKEA table. Yes, they're honeycomb inside.
Yup, every non-solid door you buy here uses a cardboard honeycomb in the centre.
Hahaha, I had the same thought 😁👍
I think it's important to touch politics sometimes, and I thought Strange Parts did it well:
It's on a topic he knows about(technology), and you can't really call his reporting one-sided if most of the other videos are about electronics in China.
It would have been something different if he just went to a rally unrelated to technology, but this is far from that, and the people complaining about the previous/this video are a mystery to me.
Keep up the great work!
I absolutely agree that it's just as important to see and hear what all spectrums of the political scene are saying about the current and future developments. I'm very happy you're not shying away from sharing some of it. It just shows that you are dedicated to everything technology and engineering.
I for one, even if i do not have any engineering background or education love to follow this space, and i'm here to see and hear what people who are more informed than me has to say about different things, as well as showing me their different findings and inventions. That's why i follow this channel. You have always been one to find new and interesting angles of attack when it comes to engineering.
Please just keep beeing you and do what you find interesting. That's what has built this channel, and it's what will keep it going.
Your fired up personality and how you engage with all kinds of people and problems. Just love it.
Thank you for yet another very interesting video.
This tech is so cool, but I was screaming at my screen all video, "ask him about elasticity!". I love wood bows and I would love to know if this would work or if it makes the wood too stiff or brittle. I can imagine a very powerful and deceptively thin bow that would be so cool.
I will ask him that for you.
I love this channel, you just never know what's going to pop up, and all of it is very, very cool. Thank you!
That look like an amazing material. I look forward to being able to play with it and see what it can be used for.
That looks very promising, especially since you asked the obvious question of flammability.
One promising approach would be to start with thin veneers formed to a complex shape, then laminated. It should beat steel for small volumes that would not be economical if a die needs machining.
I wonder how it holds up against moisture and mold etc. How long can it last exposed to the elements?
I would love to have untreated planks like these as a house siding! The natural beauty of wood far exceeds any paint.
Thermal treated wood that isn't densified will last as long or longer than pressure treated wood.
This wood is so dense rot and insects will have a hard time.
I agree with you... they need to do more test.
turned eco friendly wood veneers into galvanised square steel
Little John is gonna be delightful.
It _seems_ to me (altough I haven't seen all the facts on this) that this would solve a major problem in other engineered wood structures, which is the environmental impact of glue in laminated beams. More strenght by volume = less glue
I'm here for your content. I know that your content is always designed to inform and entertain. Keep creating the content your heart leads you to create. I'm here for it all.
Say anything these days, and some people will object.
If you say it sunny outside, someone will say it's dark where they are!
I've found that people who are unhappy with their lives, talk trash in comments all the time.
You do you and don't mind the rest. You get one life to live. Live it the best way you know how.
Yes this is the type of stuff I love to find out about. More like this. Awesome.
Great content, def here for it. 👍🏼
This is absolutely fascinating - while listening to the content here, I began to imagine everything made out of wood. Cars, Bicycles, Spaceships! It's not a simple solution for everything of course, because wood that acts like steel is (as you pointed out) as heavy as steel - but oh my goodness what effect could this have on what we build and how we build it.
I wonder if they could build a factory out here in Oregon, where much of the nations lumber comes from.
Doesn’t matter who is in office we have to work with who we got
And that's the point....
@@ShawnChristopher10101 yeah I was agreeing
It does matter who is in the office if they're an unhinged lunatic...
1. plenty of his viewers aren't american and don't care
2. plenty of people just don't care at all
Scotty. I dont think anybody who commented that was thinking much when they posted the comments about propaganda for the government. Of course it is. Theyre putting money into these things! Had to edit this because it sounded bad. I know people have there feelings but politics don't control you. They invited you to an event, you went and reported on what you saw. GREAT JOB.
Now these are the videos I was most interested in seeing from the event!
Great video! Thank you for the whole vodeo
Thanks for sharing!
My immiediate question would be: how machinable it is? Is it more similar to wood or metal (or maybe cf, gf) when cutting, milling and sanding?
Hey, this would be a great material to replace the now rotten wood frames of the Classic Morgan cars!
Someone get the hamster on the line
Not sure it would be, as the design of the Morgan and all the other timbre cars expect the strength, springiness, damping, density and dimensions of 'real' wood of whichever species. It would probably take a great deal of redesign to create a new frame in this material that can actually replace the old. Probably would be a good material to create a new wooden car with though, when every part of the design already expects the 'wood' to be really thin.
@@foldionepapyrus3441 yeah, true. I don't think the body of those cars have any rubber dampeners on them, they use the slight give of the wood as dampeners. Would probably rattle every bolt out of the body of a true Morgan
I love the colour of it. Id honestly use it for woodworking just for the colour
Love your channel, Nice to see you making videos again ^^
You should make a lot more videos like this my dude.
Finally, a wooden gym
The problem is gonna be that it's still made of basically anisotropic fibres, so the differing properties are probably gonna be annoying to calculate around.
Not saying this material isn't amazing and you can probably use it in tonnes of places, just need to think about the limitations when a salesman talks to you.
having spent a fruitless half hour on a chunk of iron bark with a block splitter...
knots... last time i checked, select timber aint cheap. not sure knots and grain imperfections take to this treatment so well...
otherwise, love it. pine squished to a hardwood...
Anisotropy is actually a good thing here. It makes beams stronger in the direction we want them to be strong. And it's been a few thousand years since we learned how to handle it.
man thats so cool, I really hope the manufacturing at scale works out economically
Fascinating new tech.
I'd be interested to see how these products stack up against traditional timber,regarding e.g. the amount of energy required in the production process and how easy it is to cut,drill,machine,etc..
There was a similar invention in the 80ies in Japan. They used microwaves and compression to densyfv and strengthen wood and improve durability.As soon as its durability exceeds the time it takes to grow it is positive in its environmental footprint!
I'd be interested in the tests that prove it's strength. The only steel has over it, from what I can see, is that steel is fire proof.
I'd seriously like to see the tests.
I'll bet steel is slightly more weldable as well.
When made dense like this the wood becomes very resistant to fire too, this is addressed in the video. A lot of metals when in the form of a powder will burn quite well. You're right about welding though.
Steel isn’t really fire proof, yeah it won’t melt or burn. But it loses a lot of its strength when heated. The whole benefit of mass timber is that the outer layer chars however the inner core will retain strength during a fire. Steel will just lose a majority of its strength when heated to 400-500C. In terms of building materials the mass timber is actually better because of this. You can account for loss of char layer by adding an inch to a wood beam or post.
Would be cool to know if the compression of the wood also helps with its longgevity. I can only think so if all water has been pushed out.
I’ve been following this research for years now. This is based off of University of Maryland research. I’ve been wanting to try this myself for personal use. I’m wondering what they use to prevent moisture absorption. That is the one thing I learned from the research paper about this process I’m sure it’s not that hard.
Now you need to visit that factory and show us
This sounds like a great product for phone cases instead of the rf shielded aluminum or titanium currently used
In WW2 some Spitfire propellers were made of densified wood.
I recall Henry Ford made a bumper for a car back in the thirtys , it was made froy or hemp. He hit it with a sledge hammer and it didn't dent.
Awesome, factory being built in fredrick, md i might actually be able to get my hands on some
I would love a floor or workbench made of this
don't let haters get you. As long as you find it interesting, post it!
Cool video! Would be interesting to see how this performs in a bike frame
What an informative video. The company representative believes in the product.
out of all of these, I think the tube is the coolest. Being able to use lignin as a replacement for carbon fiber or fiber glass for 3D shapes is very interesting
I would like to see a compound bow limbs from this material, it would show the versatility of the materials.
I was in the construction industry for a couple of years around 2010 and hated the fact I was seeing a lot of steel framed houses pop up (where the constriction is the same as a standard stick frame but using steel extrusions), it made no sense to me, sure, the steel is going to be better against moisture and termites, but where I live, termites are not an issue. not to mention, timber is a renueable resource where as steel is not, sure there is a LOT of iron in the world, but a lot of it is not easily obtainable.
not to mention the fact that timber in construction can be used as a carbon sink, planting trees is only a temporary carbon sink and once the tree has reached maturity, the amount of carbon in absorbs is low and a lot of the carbon it does absorb ends up being released again as leaves and branches fall off and decay, then when the tree dies, as it starts to rot or gets burned down in a bush fire, that carbon it has absorbed is then released.
if you let the tree grow until it is reaching maturity, then cut it down to build a house out of, you can store that carbon for another 20, 50, 100 years on top of how long it took the tree to grow. then if we do a better job at demolition and disposal of building materials, we could potentially recycle all that timber into other products like paper, currently when you pull down a house, it all just goes to landfill unless the house is built from a 'valuable' timber and it is in good condition as its a lot cheaper just to pull a house down with an excavator than it is to pull it apart by hand and sort building materials.
Great idea. Maybe when we get the 2 shipping containers in place and are ready to put up the roof, we can look at buying some of this. Or maybe we can fiiger out how to make it ourselves. I am so excited that we should have good enough weather to get those 2 containers in place this week. I am excited to finally get a place to unpack my stuff.
This is suspiciously impressive! I do wonder how its strength to weight ratio compares to steel. And also: how does it cut? How hard is it? Does it glue just as easily as steel? Is it just as dimensionally stable? Does it need varnish like wood?
Interesting! Thanks for sharing it. ✌️
Composite beams with that honeycomb would go so hard
Not only is it just a better building material, but it even looks really good. I could totally see it being used as siding on buildings, completely unpainted.
I my opinion the next thing to do is to try makeing everything we make out of expensive wood out of this thing.
Piano , baseball , bat , gun stock , cricket bat , everything where dense wood is preferend
I suppose that you can make different density wood by using variating amount of compression during the manufacturing process.
guitar
For the people asking about resistant to moisture, fungus, termites, scratching, and denting, the company's website covers all of it. One thing the is not covered, is how easy is it to cut compared to regular wood.
Imagine the bonking potential of a classic fighting staff or like a T-baton made from this stuff.
Outstanding.
Very cool,sucess for all,salutes from Brazil ❤😮
This is a genius product!
It seems like you're recovering quite well from your injury :)
This is quite amazingstill being 100% wood.
Hopefully it spurs back up the wood/logging industry
This is really promising as an idea. I'm not sure it's going to replace metal ever entirely but it sure seems like a useful resource we're underutilizing. I'm not confident, neh almost certain this won't be an overall net negative carbon producer, as it more than likely produces some making the stuff. However, if it's even slightly in the positive or just quiet efficient at storing carbon and not producing much, then it's going to be beneficial material to use.
I need a canoe built with this, super thin but super strong and light? Gimme!
hey just wanted to say that there'll always be clowns who'll hate anything you do even if it's saving a drowning child so just ignore them man you've been making really great content ever since that first iPhone video and I'm looking forward to what amezing knowledge we can learn from your future videos
You Sir, apart from the cool stuff you showed me today, with your speech, just gained a new subscriber!
Its cool they've managed to do this. Its using the same process as kraft paper, but instead of washing the lignin out theyre keeping it.
According to the research paper they remove around 45% of the lien to help with the bonds between the wood fiber
@@Shawnsrumi that makes a lot of sense! That way they can burn off that lignin in a recovery boiler to make energy to keep the process going, plus you can reuse the chemicals after to keep making product!
@@onyxpartitian I think in the paper they use an acid dissolve the lid then they heat and compress the wood to get the strength they desire
@@Shawnsrumi They use sodium hydroxide, heat and pressure. But since it's with wood chips all the lignin falls out, allowing them to wash and screen the fibre for paper and pulp.
The high density should make this rot resistant and fire resistant in the sense that it reduces the surface area that can react with air and microbes.
This is the best thing ever and it should be wide spread
I feel the major issue with this technique might be growing the wood for compressing into these forms and possibly the energy it takes to do it too. It's genuinely a great way to carbon capture tho.
I'm wondering how the weight to strength ratio would be for this material. I love it, it's like growing carbon fiber.
For a moment I thought you were doing collab with NileRed when I saw the title 😂
I'd love to. We met at Open Sauce - cool guy. Maybe it's something we can make happen down the road...
Just subscribed - partly because of my interest in inventwood, and also because of your honesty and inclusion of the importance of forward-thinking government policy. Tru dat! Don’t stop taking this stand - it is the honest facts, supports innovation, and resolves questions and misguidance in people’s beliefs. Good on ya!! And thank you.
This is really cool and I see how it could be used as a carbon fiber replacement if it's cheap enough.
I wanna see someone take a whole log and compress it radially into a super dowell
Love it!!! Where can I buy it?
What a cool video!
Good for you to address comments head on. I value that. Thank you.
This would be really cool for IKEA furniture. Remove all structural metal pieces and replace with wood-like material. Or have study designs that take less volume to ship.
Really cool tech, thanks Scotty!
Performance similar like carbon fiber, cheaper than steel
I'm so excited that means this thing can be used from big like building, vehicle, airplane, ship, submarine, train, airship to small like desktop, laptop, tablet, smartphone, smartwatch
Ammonia. Nasty stuff at that concentration
Fantastic product, using wood as the raw material.
I wonder what happens if it gets wet and does it rot ?
