Yea it
Holes can be done in an other way that seems more logicial to me :
- add points at the right locations, exit sketch
- hit "H", select point(s), "Simple" type, "Simple" tap type, distance "all", enter diameter.
Done.
You could also fiddle with "clearance" type and choose the screw type that fits in. :)
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!
Very interesting! Thank you
Imagine if you had this for those bridge building competitions in highschool :)
Amazing tutorial !!!! Really very useful ... never seen such useful information before.
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
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.
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
No bs. Straight to the topic. Absolutely loved it!
This is an excellent video! Thanks!
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!
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!
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!
You're welcome and appreciate the feedback.
Love your channel! I appreciate the content you provide.
Very well put together!
Really awesome video, thanks Stefan!
Fantastic insight, thank you.
Mind blown, great video!!!
I always wanted to know this . Thx! More on that will be welcome
Bonjour you are a really good teacher, thanks a lot!
That was awesome, thank you sir!
awesome video, thanks!
This is really informative videos. Great work.
Great video...I honestly didn't know F360 had this. What a world we live in when you can do this at home. Wow
This was great!
Good knowledge, thanks for sharing!
Thanks for sharing. Never though of doing design this way so will give it a try 👍🏻
Great tutorial!!
Really nice and interesting tutorial!
keep up the gud work bro.....it helpd me to learn the fusion topology interface within minutes!! 😍
Great video thank you for this knowledge i just bought a 3D Printer and this will help me alot
You wıll reach 100k subs in no time. Great content as always thank you !
Will be using this! Thanks!
Wow. Very nice function. Thanks.
Thank you for sharing this amazing knowledge
Thanks so much! Subscribed!
Ma fai dei video fantastici! Complimenti veramente
Your videos are fantastic! Congratulations
Suuuper geiles video, vielen vielen Dank!!
Thanks for sharing
Interesting stuff, I would like to see more of this, Love it :-)
That was super interesting. I never even realized that function was in Fusion 360.
Most excellent!
that is very clear, thank you very much
Very nice video !
Fuson 360 is powerful... thank you for video.
thanks for your video
Really interesting!
Brilliant! Thanks
Very good and interesting tutorial,
Great video. The optimized shape reminds me what you would get using truss analogy method. A video to use at universities.
Hey! Very interesting, indeed. I'll definitely look into this. Thx and thumbs-up! PS - Nice color change in 360.
Good vid! I had been meaning to record a video of this exact process.
Please still consider doing that because there isn't a a lot of good information on that topic here on RUclips.
This is very beneficial
I came and subscribed because joel the 3d printer nerd told me to. Your videos look amazing
Thanks! You won't be disappointed.
excellent thanks
Loved it. Would love to see similar sorts of modelling, and in other free to use cad software too such as Onshape/openscad/etc.
So aweome! Will look for a way to get similar results using solidworks
Very helpful tutorial. I learned something useful. Thank you!
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
Sounds awesome, did you make any vids or take pictures?
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?
Hi, Thanks for the video. I've only recently heard about topology optimization and am wondering about impact simulation ! If i use this video as an example you have defined the load point and added a couple of constraints for the mounting holes. The finite analysis includes these points into the analisys before you run the topology optimization. My question is how do you add extra loads to the model ? For instance of something knocks into thee side of the bracket adding an unexpected force if this was not defined then the bracket could fail !. Would this need to be considered at the modeling stage, the topology optimization stage or integrated into both ?
Wugga, I didn't know f360 did that. Awesomesauce! Thanks for increasing my skill set.
thx for the informative video. could you elaborate wny you unchecked y from the constraint of the bottom hole? thx!
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.
Tim Mortensen he didn't go into it, but there are settings that tell the software how the part will be made - 3d printing, cnc, extrusion, etc. Depending on these selections, the software will change placements of buttress features like this. I'm not sure if fusion has it yet, but other software packages also allow you to specify whether or not you want the part to be symmetric about a given plane as well. Hope this helps.
I haven't been able to find anything in Fusion 360 to set that it's a 3d printed object for that sort of thing. Do you know where it may be if there is such a setting?
The software generally deploys a generative algorithm, so the initial source of the structure is random. And the algorithm tries to make it better with each iteration.
@@smithe53 Where is that setting for the output? I normally use a cnc more than the 3d printer.
Yes - it is a discretisation artefact which occurs because he runs the optimisation on an asymmetric mesh.
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?
This is the rPLA I printed with, which works totally fine. Only did some minor tests with the rPETG, so I can't really say much about it.
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.
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?
Really learn something today, thanks!
Would you consider showcasing every simulations in Fusion 360 in practical projects?
I'll be taking a look at some of the others in the future.
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
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
Can you give me advice about how I should do? I made a form of a planter from thin cardboard. I want to make it more rigid to avoid shape-changing when I will pour concrete into it. I made a 3d model of my planter in 3ds max before. How I should do constraints and loads in Fusion 360?
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?
Спасибо!
hi can u post how a topology optimization is done to obtain compliant gripper using hypermesh software or fusion 360
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.
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 agree. And with the use case and the static loads he is using. The default mess look entirely adequate. What he did was way too fine.
Yet another nice tutorial! :) Thanks!!
What screen-capture software do you use to make the video?
Just purchased Snagit yesterday and I'm 90% satisfied with it.
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.
i guess you could cad the infill and wall thickness as part of the design if you really need but it would be painfull and not a perfect solution
a very very useful video! thank you so much. but I have a question about the FE analysis of the finished Piece.
is there any possibility to simulate it with anisotropic material (like the 3D printing do)?
I'm quite sure that it's not possible in Fusion 360, but any other descend FEA software should allow that.
Could you include the generated model stl on thingiverse? I love the organic look.
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!
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.
Would be cool if a slicer program could generate an "ideal 3dp mesh" to test on loads virtually!
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 😁
is it possible to only optimise a part in 2d in this program because I want to make my part out of an aluminium sheet
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.
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
Interesting thought, there might be softwares out there. But I would say that the strength of a 3d print practically only come from 3 key elements, thickness/number of perimeters, orientation of the layers and the quality of the bond between layers.
Even with an accurate STL of the sliced model only the thickness of the walls could be accounted for in a simulation on fusion. Simulations are all theoretical and used mostly to speed up human analysis. Meaning let the computer do calculations and then use humans to look and decide if results are appropriate or if a revision is needed. Humans still out think computers, machines are just quicker not better.
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.
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 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.
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?
My personal opinion is that "softening" optimized designs is a really bad practice in a lot of cases and especially in the, the redesign is pretty easy.
Already more in the pipeline 😉
What a pity that shape optimization feature is not free...
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!
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!
I think it doesn't matter. The simulation assumes homogeneous tensile strength throughout the part and goes from there. This is also why these simulations can only get a reasonable approximation for 3D-printed parts, as they are shells with a small percentage of infill (not at all homogeneous).
Can someone please explain to me why that truss was offset to one side, instead of spanning the entire thickness of the structure? Shouldn't the solution be symmetric in that axis since the load was given to be straight downward?
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.
why is there no straightforward way to convert from optimized mesh to sketch?? Ive looked at solidworks optimization workflows too, and it requires manual sketching.
I've got Fusion 360 but it's asking me to buy cloud credits to do this. Is that normal or am I missing something?
How do I mirror the part to allow for the other side? Thank you for the great tutorial.
You can mirror it on any slicer.
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.
:-)

So if you do these simple topology optimizations, with only one part, then the material is negligible because you maximize stiffness (here the norm of the strain energy is used) and are only looking for a mass percentage. You could actually replace mass by volume. Actually even the magnitude of load doesn't play a role if you only have one load case. You could set materials but if you work with isotropic materials (with no crazy Poisson's ratio) the result wouldn't change a bit. If you go more advanced (assemblies, orthotropic materials, numerous load cases) then these things come into play, but then the problem gets really complicated. There is a reason why I said, that this takes years or even decades to master.
