@@AmritGrewal31 I meant what I said. To 10%. Complex assemblies are often a requirement of the manufacturing capabilities you have access to. When manufacturing those geometries becomes "click print" (this is an oversimplification) you wipe out parts, fasteners, brackets, etc.

there is one big misconception about "strong" and "optimized". optimized geometry parts are not particularly strong. they have better weight/strength ratio, yes, for one particular load scenario which they are optimized for. "optimization" means that we leave only material which is necessary for carrying a particular load, removing all material making part weaker for other (unexpected) loads and therefore unreliable.
I mean, that's also where the bigger chunk of FEA comes in, and if you're truly designing a part that has a real world application outside of normal parameters, you can get close but there's nothing better than physical testing.
But if the part is designed to support a certain load of 500 N, then you can make it support 5000 N. It will have a lot more of material but also will be stronger and support other loads you didn't think of.
@@sayingnigromakesyoutubecry2647 If you use the same volume/weight of metal that supports 5000 N and use optimized geometry, you can support maybe 20000 N.
@@sayingnigromakesyoutubecry2647 I see, I thought you meant that it would be better to not optimize and just fill the space to make it stronger. I misunderstood your point.
The heavy part broke at about 50 While the topologically optimized broke at 45 For 60% weight savings this is well worth it and another iteration where you try to strengthen the area that broke might move the weak point to the same location it was in the original part Even with a bit of added material 50% weight savings with the same breaking point both at 50 kg or 50lbs is beyond amazing

For anyone curious, Bernoulli and Euler's blood pressure measuring method basically involved jamming a glass tube into a live artery and measuring how far the blood climbed up it. Interestingly this method of measuring pressure is still used today in aircraft - Bernoulli's calculations inspired the Pitot tube which almost all aircraft use to calculate airspeed by measuring the air pressure inside it.
Love this introduction to topology optimization. It had been a while since I've looked into it. It's surprising how much matter is wasted on commonly designed parts, I for one would love to see more topologically optimized designs.
Thanks! I agree, as it becomes more viable for local solutions, i.e cloud based or not needing a week to run a study, I feel it will become a basic design step.
Brilliant explanation - clear, witty and comprehensive. You should apply for the job of my Engineering professor. I'll see if I can arrange his early retirement.
Great vid. Just an FYI, "Euler" is pronounced "oiler" rather than "yewler" - I didn't find out myself until after maybe a decade of saying "yewler". :P
He's doing everything I wanted to do... generative design, active suspension, active aero, freevalve tech... all homologated into a technological marvel (I'm glad to see someone with the knowledge to do so)
With a budget, I'd do a track car project such: 1 - ground effect maximizing false floor, think carbon, bit like in F1. 2- It's mounted to the four wheel uprights, making it unsprung aero. Yes, unsprung mass, boohoo 3- Light wheels, whatever they look like 4- Chassis that holds payload and to which suspension is mounted. 5- Shrink wrap body to minimise drag and have positive effect on downforce, depending on active aero shapes.
6:24 I've never seen this formally explained. i only ever saw the practical application where you can let gravity pull on a plastic shape, and the shape it forms will be that objects strongest compression shape against gravity when you invert it. For example, the arc that a piece of paper makes when draped between two points (a catenary) will be that paper's strongest shape in compression. i've seen this used with resin casting to make bridge supports or other similar shapes. you can also use a chain to trace out a catenary shaped mold for concrete to make an arch
Thank you so much for making this video, and a special thanks for talking about the history of it, which was especially interesting. This video is especially helpful to me as I'm attempting to design a space frame chassis out of cardboard as an application to an FSAE team, and I wanted to learn more about the mathematics involved in calculating something like this. I know it kinda divides the audience sometimes, but I love when you talk about the mathematics and theory behind it, and especially when you apply that theory so it doesn't get boring.
This is perhaps one of my favourite videos of yours. I’m an engineer and total Euler fanboy. Like, I tried to convince my wife we could name one of our kids after him. We only have daughters.
Just discovered your channel. Your seamless mix of deadpan comedy and scientific explanations delivered in a way that even a simpleton like me could understand was very refreshing. Subbed
Thanks for making this vid. As a kid I developed my own understanding of basic engineering, like we all do. Some of the intuitive stuff was wrong, like thinking folding wings on aircraft could never work because only long, straight beams could ever be strong. But from early on it seemed like things were designed wastefully and just dumbly. Human-made stuff often seemed lazy and to rely on using overly heavy/strong materials and then placing supports etc in vastly sub-optimal places that relied on the over-engineering. A little extra thinking and design could have resulted in much better use of the resources, while also making the item just nicer. Some much urban design and civil engineering is ugly and off-putting. That was a gut feeling that I've never forgotten and it's awesome to randomly see this vid of yours. I'll go back and see if you've gone more into this. I like the way you think!
Cool. Hey would you design a car wheel optimised for weight? I’ve been wondering what would optimal car wheel look like, if aesthetics and brakes are not an issue.
You have to define "car" really carefully. If it's made out of steel and rolls, I'll give you a nail. If it moves under its own power, I'll give you a helium balloon. So forth.
@@Asdayasman I believe he wants a car wheel though, like the metal cylinders that hold the tires. Cuz a whole car would be difficult, as you described.
I haven't actually seen a full analysis, but I believe it ends up serious to most of the wheels you see which have Y shaped spokes. As in, a single point coming out from the center of the wheel, splitting into two points which go to the outer rim. Several of those repeated. Tend to be the lightest wheels with the most strength. Add this sort of optimization and they become smoothed and curvy with some wider and skinnier parts. Just my general guess and drawing from old memories. I could be way off.
Layman here. Those initial designs you flashed up really remind me of biological extractions. Like, mimicking trees and musculoskeletal assemblies. Biomimetics, I think, is the term?
@@WesleyKagan Superb! Leaving smarter than I came in. I guess Nature has been doing this sort of thing for aeons. Makes sense to sort of crib her blueprints for the some of the starting points. Hope the move goes well. Bigger castle, bigger booms.
Idk why I was recommended this, couldn't understand 70% of what was being said, but now I have 30% of understanding that stresses ,materials & design play a big role in making structures efficient. So I've got the curiosity going for me, which is a 100% win.
This technology is HUGE for people using laser sintering metal 3D printers. The material is expensive and the print times are sometimes measured in days. This makes manufacturing larger and larger parts practical, and makes smaller parts cheaper and easier to make, because you reduce the distance and time the laser has to fire per layer
If anyone is wondering about the Blood pressure, the Bernoulli effect was used to calculate a person's blood pressure by using a straw in their skin and to see how fast the blood would move.
You may or may not already be familiar, however one company doing topology optimization, Altair, has some neat ideas that (from what I understand) go beyond the optimization of Solidworks or Fusion 360. I'm part of a collegiate FSAE race team, and Altair came by our university a couple months ago with a small seminar, helping us optimize a few parts and giving us the run down on some of their software. One of the really interesting things is how the mathematics used in their optimization heavily rely on research done into the way bones grow in animals; their theory was essentially "nature already seems to have this figured out, why change it?" A lot of the parts created with this software somehow managed to look even MORE alien and organic than what you've already shown in this video.
Yeah, Altair is doing some VERY cool stuff right now- I mean, it's fantastic stuff but also I have a feeling that I couldn't afford to walk in the door of their building, let alone explore their suite of design and AI programs... Although if they are listening want to send it over, I promise I won't be responsible with it.
I don't know how I found this channel. I'm studying engineering but none of the "real" engineering stuff rather software engineering but this was so interesting and I was glued to my seat the entire time.
I'm not an engineer, but interested in cars and bikes. And I want to thank you for such a compact and surely a lot simplificated explanation of topology optimisation! This is awesome and what is peculiar about it is that it looks so bio and close to something created by nature) Cool! Big up and sub! Thank you giving content that internet was originally made for)
Anyone who wants to show off their copy of "Godel, Escher, Bach" has my attention. I appreciate the wide range of your interests, and your ability to transition from the theoretical to the practical. My only wish: more content 🙂
They are so organic forms, it remembers me to the Guadi art, he tried to replicate the ways of the nature because in his opinion was not only more resistant but it was close to his concept of God, in connection with the nature.
Stumbled across this video, because of the biomimetic screenshot. I see a pedantic computer mounted to a wall. I listen to the introduction, I see a Gödel, Escher, Bach book on the other side. By minute 4:38 I am still waiting on biomimetic part modelling, but have already heard about Euler, Bernoulli, fluid dynamics and graph theory, a repeatedly bad pronounciation of Königsberg (which - btw - is also famous for its Königsberger Klopse) and topology. I arrived finally at 7:52 where an object after being designed by applying topology optimization and manufactured by additive synthesis shows great properties. Yeah, I'm going to subscribe.
This was fantastic on many levels, but I appreciate the conversation in the comments nearly as much as the content. This (and you, WK) made my day. Thanks.
As a math teacher who bores his high school students with tangents into materials engineering, topology, graph theory and biomimicry, this is dead on the money for stuff that gets my gears going. Look at a bird skeleton or the roots of trees next to products made in 3d printers after optimization, it's almost like natural evolution is the world's greatest R&D department.
First video I have seen of yours wesley and I'd like to let you know you immediately hooked me and your sense of humer is one I strive for in my videos! You are so well research and I can thank you enough for that!
I "obtained" SW2012 and all I ever did with it in a decade was make some dope ass rims. Its nice to see what you can do with all the *works it comes with if you know what tf you're doing. Good stuff.
7:59 I was designing and building and flying that structure type with balsa wood years ago. Some of this becomes apparent by hands on experience. I admit a cruder facsimile yet important enough to undertake with definitive results.
Incredible video and explanation! It was awesome to see where everything came from and how it came together over time and how technology changed its uses.
Short answer is that sharp corners are generally bad because they're concentrated stress points, but they're much easy to make through traditional means before the 3D printing era.
So basically it means, that stuff doesn't have to be solid anymore - but can be made lighter by "skeletonizing" while still keeping an optimal strength? We all had an idea of that or something along those lines, but was nice getting a solid explanation. You're doing very well in front of a camera, keeping focus and maintaining a connection to your audience. Thanks once again.
The way you explained the role of optimization and FEA is idealized a bit I think. Maybe not exactly "idealized;" your explanation was exactly what it was conceived to do, but I think more often its implementation is that of making a given widget only as strong as it has to be in order to last a couple of weeks past the warranty expiration. How many times have we heard "they just don't make things like they used to?" When people say that, they're referring to things that predate FEA and were designed on intuition rather than simulation; things that were "overbuilt" by today's standards. I'm glad we have optimization and FEA for things like race car engines and space-going rockets, but for things like tractors and coffee makers I'll take "overbuilt" above "optimized" any day of the week.
Which is acceptable and perhaps a market that needs filling. I think many people would rather pay more to keep something for a decade or longer than replace a cheaper object every few years.
First off, nice Deltron 3030 wallpaper on your pc! Second, cool video. Engineering is satisfying when someone else is doing the calculations. I failed out of uni :P
Those structures and that divan in particular looks like something Carlo Mollino would've come up with had he had access to modern computing power and manufacturing methods...Which makes some of the things he designed going back to the 1940s with essentially a pencil, paper, slide rule and intuition and how local Turin shops like Apelli & Varesio were able to manufacture them with what they had even more astonishing.
I think topo opt refers to the topology of the mathematical problem being solved, not the actual geometry undergoing optimization. You can apply topology optimization to an abstract mathematical problem with no geometrical representation.
Great video. But Euler is pronounced like "oiler" as used in that sweet 928 at the end there. Took me almost a whole semester to learn that back in the day. Very interesting topic, with history in there too.
Highly enlightening, your explanations are concise and easily comprehended. You have inspired me to try out these features in F360. More videos of this nature please!

If your explanation starts with " ... and I need to put my history degree to use...", you've hooked me right there!
Thanks for the great video!
Hmm, I wonder whether you're considering creating a land speed racer :)
Idk why I was recommended this, couldn't understand 70% of what was being said, but now I have 30% of understanding that stresses ,materials & design play a big role in making structures efficient. So I've got the curiosity going for me, which is a 100% win.
Glad to hear it! I like to get people interested in very, very specific stuff.
Any progress on the all mechanical computer?
Wes mate I gotta say I love the way you break concepts down. From one teacher to another, really good job.
Algebraic topology is a incredible field... and probably one that holds some fundamental answers about our universe
Just noticed Godel, Escher, Bach on the bookshelf - one of my top 5 favourite books. A real classic.
This technology is HUGE for people using laser sintering metal 3D printers. The material is expensive and the print times are sometimes measured in days. This makes manufacturing larger and larger parts practical, and makes smaller parts cheaper and easier to make, because you reduce the distance and time the laser has to fire per layer
If anyone is wondering about the Blood pressure, the Bernoulli effect was used to calculate a person's blood pressure by using a straw in their skin and to see how fast the blood would move.
You may or may not already be familiar, however one company doing topology optimization, Altair, has some neat ideas that (from what I understand) go beyond the optimization of Solidworks or Fusion 360. I'm part of a collegiate FSAE race team, and Altair came by our university a couple months ago with a small seminar, helping us optimize a few parts and giving us the run down on some of their software. One of the really interesting things is how the mathematics used in their optimization heavily rely on research done into the way bones grow in animals; their theory was essentially "nature already seems to have this figured out, why change it?"
A lot of the parts created with this software somehow managed to look even MORE alien and organic than what you've already shown in this video.
Yeah, Altair is doing some VERY cool stuff right now- I mean, it's fantastic stuff but also I have a feeling that I couldn't afford to walk in the door of their building, let alone explore their suite of design and AI programs... Although if they are listening want to send it over, I promise I won't be responsible with it.
I don't know how I found this channel. I'm studying engineering but none of the "real" engineering stuff rather software engineering but this was so interesting and I was glued to my seat the entire time.
I'm not an engineer, but interested in cars and bikes. And I want to thank you for such a compact and surely a lot simplificated explanation of topology optimisation! This is awesome and what is peculiar about it is that it looks so bio and close to something created by nature) Cool! Big up and sub! Thank you giving content that internet was originally made for)
THAT WAS RAD. This is all I've been thinking about. It was awesome to hear the history as well
Anyone who wants to show off their copy of "Godel, Escher, Bach" has my attention. I appreciate the wide range of your interests, and your ability to transition from the theoretical to the practical. My only wish: more content 🙂
Your humour is so subtle but hilarious, love it sick video
They are so organic forms, it remembers me to the Guadi art, he tried to replicate the ways of the nature because in his opinion was not only more resistant but it was close to his concept of God, in connection with the nature.
Cool wall computer! Maybe my next computer can be cool like that. Thanks for explaining the math and history behind the weird shapes.
Love that you have Godel Escher Bach on display. Wonderful.
Holy shit, Deltron 3030 is so underrated. I love that you have it on your monitor.
That Euler joke had me LOLLing out loud. M dog looked at me like I'm weird. Perfect.
928 and Deltron 3030! Awesome and informative content. What more could one ask for!
bro just by watching a frame of your content i know i must suscribe, that deltron 3030 walpapper, the pc on the wall ufff based
Stumbled across this video, because of the biomimetic screenshot. I see a pedantic computer mounted to a wall.
I listen to the introduction, I see a Gödel, Escher, Bach book on the other side.
By minute 4:38 I am still waiting on biomimetic part modelling, but have already heard about Euler, Bernoulli, fluid dynamics and graph theory, a repeatedly bad pronounciation of Königsberg (which - btw - is also famous for its Königsberger Klopse) and topology.
I arrived finally at 7:52 where an object after being designed by applying topology optimization and manufactured by additive synthesis shows great properties.
Yeah, I'm going to subscribe.
This was fantastic on many levels, but I appreciate the conversation in the comments nearly as much as the content. This (and you, WK) made my day. Thanks.
I completely agree! The conversation in the comments is one of my favorite parts of having a channel.
I looked it up the blood pressure thing and ooooooooooh boy, am I glad someone figured out a better method.
first video of yours i watched. loved your personality and the nonchalant info dumping. love the content!
As a math teacher who bores his high school students with tangents into materials engineering, topology, graph theory and biomimicry, this is dead on the money for stuff that gets my gears going. Look at a bird skeleton or the roots of trees next to products made in 3d printers after optimization, it's almost like natural evolution is the world's greatest R&D department.
It really is. I'm glad we are at a point where this is possible technologically.
@@WesleyKagan I'd love to see you do a video with biomimicry influenced design!
didn't understand a single thing but i still watched the whole video.. why am i like this?
I am incredibly glad I subscribed to you. Watching your videos require me to be in a certain mental "mood," but I never regret it when I click on one.
I've watched many an hour of CZcams and this is the first time I've seen the class presentation style used: refreshing.
That ad after you said you like monetization, goated
I've been wondering about this for years. Thank you for the answer
love your wall-top computer!
One of my cars on your desktop.
And two on your wall! Good man.
First video I have seen of yours wesley and I'd like to let you know you immediately hooked me and your sense of humer is one I strive for in my videos! You are so well research and I can thank you enough for that!
I stopped taking math in high school pre calc and mostly understood this. Very well explained!
Thank you!
GEB is as such a cool book! Thanks for the video!
It’s a great book!
I "obtained" SW2012 and all I ever did with it in a decade was make some dope ass rims. Its nice to see what you can do with all the *works it comes with if you know what tf you're doing. Good stuff.
Short and on point. Thanks!
Thanks for watching!
7:59 I was designing and building and flying that structure type with balsa wood years ago.
Some of this becomes apparent by hands on experience. I admit a cruder facsimile yet important enough to undertake with definitive results.
Just wanted to mention, computer looks insane. Really cool idea.
Incredible video and explanation! It was awesome to see where everything came from and how it came together over time and how technology changed its uses.
Love that you showed ASUs website, forks up!
Whoah, just noticed the Deltron 3030 album cover. Deep cut. Respect has gone up 40%.
This was a very good video! Educational and funny, I am glad to have found your channel and have subscribed.
Short answer is that sharp corners are generally bad because they're concentrated stress points, but they're much easy to make through traditional means before the 3D printing era.
I love how these structures end up looking organic
So basically it means, that stuff doesn't have to be solid anymore - but can be made lighter by "skeletonizing" while still keeping an optimal strength?
We all had an idea of that or something along those lines, but was nice getting a solid explanation. You're doing very well in front of a camera, keeping focus and maintaining a connection to your audience.
Thanks once again.
The way you explained the role of optimization and FEA is idealized a bit I think. Maybe not exactly "idealized;" your explanation was exactly what it was conceived to do, but I think more often its implementation is that of making a given widget only as strong as it has to be in order to last a couple of weeks past the warranty expiration. How many times have we heard "they just don't make things like they used to?" When people say that, they're referring to things that predate FEA and were designed on intuition rather than simulation; things that were "overbuilt" by today's standards. I'm glad we have optimization and FEA for things like race car engines and space-going rockets, but for things like tractors and coffee makers I'll take "overbuilt" above "optimized" any day of the week.
Which is acceptable and perhaps a market that needs filling. I think many people would rather pay more to keep something for a decade or longer than replace a cheaper object every few years.
my eyes keep getting drawn by that sets he had on the wall, damn that thing is LIT! I don't care WTF is that but I want one too!
First off, nice Deltron 3030 wallpaper on your pc!
Second, cool video. Engineering is satisfying when someone else is doing the calculations. I failed out of uni :P
Haha, the best engineering is the engineering you don’t have to do yourself. Think I should stitch that on a pillow.
That is so cool, have an organic look, reminds me of bone structures. And the video was also funny
Those structures and that divan in particular looks like something Carlo Mollino would've come up with had he had access to modern computing power and manufacturing methods...Which makes some of the things he designed going back to the 1940s with essentially a pencil, paper, slide rule and intuition and how local Turin shops like Apelli & Varesio were able to manufacture them with what they had even more astonishing.
Video is put together so well. I didn't lose focus once
one day i might understand more than half of the video, still heaps interesting. love ya work wesley
I was just wondering about this. Appreciate the video!
I think topo opt refers to the topology of the mathematical problem being solved, not the actual geometry undergoing optimization. You can apply topology optimization to an abstract mathematical problem with no geometrical representation.
Nice choice of wallpaper there on the right monitor!
Great video. But Euler is pronounced like "oiler" as used in that sweet 928 at the end there. Took me almost a whole semester to learn that back in the day. Very interesting topic, with history in there too.
A wonderfully playful dip of toe into hard engineering for this non-engineer. Thanks!
Glad you enjoyed it!
Great video! Love the wall mounted computer too...
That PC with all the parts attached to the wall is awesome
Highly enlightening, your explanations are concise and easily comprehended. You have inspired me to try out these features in F360. More videos of this nature please!
Noted! Thanks for watching!
Seriously need a part two to this video.
