The main difference between your channel and other 3D-oriented channels is that you tackle many technical issues, such as this, the one about the infill strength, etc. Thanks for that!

Imagine if you had this for those bridge building competitions in highschool :)

What a great video. As a very novice Fusion 360 user I never leave the modelling environment - I guess it's time to! Also, the visible highlighting of the shortcut keys makes it much easier to follow along. I wish every youtuber doing Fusion 360 videos would add that

Very interesting! Thank you

Amazing tutorial !!!! Really very useful ... never seen such useful information before.

this Video is absolutely great, I love it. I'm a mechanical engineer using Catia V5 (sparsely using the integrated FEM Analysis), and it's incredibly interesting to see how FEM Analysis and Shape Optimization is integrated into Fusion!

No bs. Straight to the topic. Absolutely loved it!

Thank you really much for making such extended tutorials, the topics you choose are really, *really* helpful and the amount of detail you put into them make it super easy to pick up; even if topics are as abstract as this one.

The amount of quality put in your videos is astounding. Quality of information & rigor. Kudos I hope you go far in this

Seriously one of the best videos 3-D printing related topic videos I have ever seen, also one of the best advanced fusion 360 videos I have ever seen. Thanks!

Is there a reason why the simulation would put a support asymmetrically when the constraints and forces are all applied along the centerline of the part? It works out nicely for printing but seemed strange.

Yet another AWESOME tutorial from you. I'm new to the 3D modeling and printing world and your videos are very rich in information. Learned so much from you. Keep it up.

Great video...I honestly didn't know F360 had this. What a world we live in when you can do this at home. Wow

i work on a students race car and we used Topology Optimization for nearly every part and these parts look so beautiful. purly functional, nothing there whats not needed

Hey man, i have a suggestion that in such build you should set infill at 100% to achieve actual results. Reason for this is that Topology Optimization do not calculate infill. It calculate topology for full-body solid object, and infill will broke equation. What i want to say that with 15% infill there will be totally different optimized shape that without infill 100% and program do not calculate it.

FEA simulation is going to be off more because of the weak z axis and layer bonds rather than the infill. Infill does not really weaken parts that much, not as much as they are weakened by poor layer bonding. Really nice video, thank you!

wow, I didn't even know that! A few weeks ago I was designing a filament holder myself in Fusion 360 and this would've been really handy... Nice video!

I'm not sure if Fusuon allows for changing element size in areas but you only need the smaller ones near the stress concentration areas. Could get by with way less elements, especially if Fusion has plate elements

I came and subscribed because joel the 3d printer nerd told me to. Your videos look amazing

Bonjour you are a really good teacher, thanks a lot!

This is an excellent video! Thanks!

If you are watching this video in Sept. 2020, you know why to never rent software thanks to Autodesk once again fucking over the consumer.

Damn, looks like I won't get to try this as simulations will be scrapped for Fusion 360's hobby version. :'( You'll have to do this tutorial under Solidworks!

You wıll reach 100k subs in no time. Great content as always thank you !

I looooove these segments! It's such a good basis for further experimentation. Thanks! Nice to see you're using FormFutura recycled petg, I don't see many creators do that (recycling that is). I'm testing it right now but it does seem a bit brittle at any temperature, did you experience that?

Great video. The optimized shape reminds me what you would get using truss analogy method. A video to use at universities.

keep up the gud work bro.....it helpd me to learn the fusion topology interface within minutes!! 😍

You should use quads instead of triangles for the mesh. Triangles create artificial stiffness

Thanks for sharing. Never though of doing design this way so will give it a try 👍🏻

That was super interesting. I never even realized that function was in Fusion 360.

I always wanted to know this . Thx! More on that will be welcome

As 3D parts’ strength comes mainly from the perimeters, would you be able to approximate the analysis a little more if you made a hollow version of the part? Excuse my grammar 😅 Ps: Your content is awesome

The hard edge on the upper mounting bracket is a weak point and should also be modeled organically. Because what's the point in maximizing the rigidity of the body if the attachment is weak..? It's like having a steel part screwed to a cardboard part ._.

Why did the FEA show the cross support to be on only one side, the 'bottom' of the model (in fusion)? You made that support only half width as well when you made your design, but in the axis the forces and supports were fully symmetric.

What a pity that shape optimization feature is not free...

Wugga, I didn't know f360 did that. Awesomesauce! Thanks for increasing my skill set.

Thank you for the tutorial. TO is the essential tool for AM. We are looking forward to see the next one. A couple of comments: - Following your design strategy: in order to keep the original dimmensions of the design you could Project the initial sketch to draw the arc of the holder. - Alternative way: Why you haven't convert the STL to solid and then correct/soften the desire areas?

Great video thank you for this knowledge i just bought a 3D Printer and this will help me alot

Ma fai dei video fantastici! Complimenti veramente Your videos are fantastic! Congratulations

Really learn something today, thanks! Would you consider showcasing every simulations in Fusion 360 in practical projects?

Good vid! I had been meaning to record a video of this exact process.

Really awesome video, thanks Stefan!

Love your channel! I appreciate the content you provide.

Is there a way to force Fusion 360 to do the analysis locally? I'm not a fan of the 'cloud credits' thing Autodesk has going on and I'm perfectly fine with waiting longer if it's all local to my machine.

Regardless of whether the static stress simulation is accurate for the printed material, I still think it would be interesting to run both the original and the optimized shapes and see how much weaker the optimized part is.

Fantastic insight, thank you.

Fuson 360 is powerful... thank you for video.

Loved it. Would love to see similar sorts of modelling, and in other free to use cad software too such as Onshape/openscad/etc.

Thanks for sharing Interesting stuff, I would like to see more of this, Love it :-)

Why did you not fully constrain the lower point? And I always thought that Slic3r is pronounced like slicer.

Mind blown, great video!!!

You may be able to shell and then add a "cap" - top layers, maybe join body, hopefully 360 leaves the inner cavity open. Then specify your material and try an FEA?

Did you at any point select the final material the part is gonna be made out of? Does it matter at all for this optimization? thx!

Hollow the part for the fillament space which doesnt contribute .And you can do the fea And do the shape op with a hollow part too 😁

So aweome! Will look for a way to get similar results using solidworks

Very well put together!

Servus Stefan - Merci, great video as always! A learning question from the engineer who installed Fusion360, but always uses the software he has been using for 20 years when something needs to be constructed. It's a shame, I know. But it is what it is. However, when I see something like this, it motivates me to make the switch, however: At what point in this FEM process do the material properties such as weights or stress tensors actually come into play? Are they hidden somewhere in the settings or is it all based on the freely chosen percentage of material savings, which would not be so tingling after all. I assume that the answer here will be more concise than the question, or could give rise to a separate video, because you have mentioned the imponderabilities of FDM printing. I pull the crippled strut inside in this form (quite constructively) a bit in doubt, but it is also very funny - so why not follow the software. :-) Translated with www.DeepL.com/Translator

Will be using this! Thanks!

awesome video, thanks!

thanks for your video

that is very clear, thank you very much

Hey! Very interesting, indeed. I'll definitely look into this. Thx and thumbs-up! PS - Nice color change in 360.

Wow. Very nice function. Thanks.

Thank you for sharing this amazing knowledge

You've got good videos and descriptions, well done. The one thing that drives me nuts is how slowly your intros wrap-up, the "I'm Stefen and welcome to CNC Kitchen!" part seems to take F-O-R-E-V-E-R. It was amusing the first video, but made me want to jump out the window (or just click away) by the third time I heard it. 2-3 seconds max, not 5. I know it seems trivial, but when you have quality editing and planning (which clearly you do) such rough edges stand out.

This is really informative videos. Great work.

great video! thank you so much. I have one question/observation: although the load and mounting holes are symetrically placed on the part (mid point), the optimization results in an asymetrcal design with the middle truss member being offset to the right. can anyone explain why this is?

Thanks so much! Subscribed!

Suuuper geiles video, vielen vielen Dank!!

Would be cool if a slicer program could generate an "ideal 3dp mesh" to test on loads virtually!

Good knowledge, thanks for sharing!

Most excellent!

Is it just me or this feature is no longer free on the new personal license?

Really nice and interesting tutorial!

Thanks for the great Tutorial. @ 15:25 you say that you wouldn't recommend to print it as it is, but you don't say the reason why. Could you provide a reason to why one shouldn't print the optimized topology as it is. Thank you.

That was awesome, thank you sir!

This was great!

The last time i worked with finite elements was helping somebody optimising some old code for calculating chemical penetration depth. 3 mm grain size - that is ginormous XD I think we were working on something like 20 nm. of course that was not running on a normal home computer.

Very good and interesting tutorial,

Ese es el perfil optimizado para un punto en la horizontal que recibe la fuerza. La fuerza la recibe la barra, y la reparte entre dos elementos. Tal vez la forma sea un tetraedro.

That was a pretty awesome tutorial, I sure would like to see a lot more tutorials in the future,... I can't even design a 30mm bed levelling knob in Fusion 360, yet, because I don't know where everything is, tools-wise. anyway, I came from the 3D Printing Nerds, Channel and loved what I saw and had to subscribe. Simple tutorials with-in fusion 360 when you have time, thank you.

I didn't know about this feature until just now!! What is not really clear to me is why did you uncheck the UY axis in the 2nd constraint. Thanks

Brilliant! Thanks

@9:11 you show the load coming in from a single direction. I would think the load would also be coming in from the sides and front-to-back as a smaller force. In this case, with no side-to-side load, your project will be very floppy, as in a piece of paper. It will be strong in 2 dimensions, but not in 3 dimensions. Possibly I am missing something..

Great tutorial!!

This is very beneficial

Very helpful tutorial. I learned something useful. Thank you!

Very nice video !

Thanks for this informativ video. My Question is, is there a way to get the Model in a sliser generate an infill generat an .slt, put it back to fusion and run a simulation

If you changed the design so that the spool is supported not in the middle but more in line with the top hole. Would it save more material?

At which point the simulation takes into account the material? Maybe I missed it in the video. But I guess the reaction to 100 N it's not the same on a 10mm steel beam or a 10mm crystal bar.

thx for the informative video. could you elaborate wny you unchecked y from the constraint of the bottom hole? thx!

excellent thanks

Awesome job, but I'm wondering why you don't need to set a material before doing the optimization? Because wouldn't different materials require different structures to support the 100N force?

And there we have it... at least 1 semester of college in 20 minutes... seriously now, those places are only neccesary to get that piece of caedboard with your picture on it

Really interesting!

Hallo Stefan, Vielen Dank für das perfekt geklärte Video. Ist das möglich die Topologieoptimierungs-Ergebnisse im offline-Modus zu öffnen. Wie und in welchem Format sollte das gespeichert werden? Danke im Voraus. Amer

Yet another nice tutorial! :) Thanks!! What screen-capture software do you use to make the video?

You know even if you printed as just a shell, you could back fill with 2 part epoxy, making i think even stronger
