Great content as always bro. Super stoked you introduced me to mesh mixer. I want to design and 3d print a lamp shade, and now I have even more tools to make some cool shit!
Great demo and process, thank you! One comment, though: Asymmetric structures from optimization will (virtually) always give asymmetric stress distributions (due to the asymmetric stiffnesses wrt the middle plane). Thus, you will most likely lose significant performance if you just mirror the side you like best.
Yo this is hilarious .... I fell upon generative design/topological optimisation 2 years ago ...... and for my very first project i also tried to improve the skate truck 😂
This is great stuff! Did you ever try lost PLA? I saw you sent a few DMLS prototypes to the guys at Braille, but I'm looking to do something similar and DMLS is out of my price range. I imagine there might be a lot of people in the same boat and curious to learn how feasible manufacturing something like this is with more DIY techniques.
Hi Paul, Thanks for the great tutorial . I know the vid is a bit old now, I am trying to achieve an aesthetic pleasing result using the volumetric lattice in fusion as the starting shape for generative design like u did in the video, the resulted object is not readable in the generative design environment , I tried to convert it to mesh and still can't use it as starting shape , As for Meshmixer I wasn't able to do the lattice with it , any suggestions?
Very nice video! How do you mean when you say (7:37) you will print it in PLA and cast it? Do you use the PLA print as a positive to make a mold? Would be very interested to hear more details about this!
Look up "lost PLA", it's been around for quite a while and there is several videos of people showing various techniques. In a nutshell, yes, you basically use the print as a positive to usually make a plaster mold. You then just use that mold to cast the metal during that the PLA burns away due to it's low temperature resistance. Lastly you dissolve the plaster and voilà you have the print casted in metal.
Hi Paul, Nice video! Why did you need to create a latice? Why not just use the exported sat as a seeding geometry? How much of weight where you able to reduce? Next step now looks like the axis could use quite a lot of weight reduction. Curious to see that whole assembly optimized . Let me know if you need a hand, we could do some community driven engineering :-)
Hi David! Great question, something I should have covered in a bit more detail (will remember that for next time!) you could absolutely use the exported SAT as the seed geometry, but because generative results will vary based on the seed geometry, I added the lattice to see if it would net me more aesthetically pleasing results! If you have anything you'd be interested in me having a stab at for a youtube video, HMU on twitter DM's and let's have a chat!
@@paulsohi9015 really cool, thanks, Paul! My company recently started looking into this AutoDesk product, though we use Siemens NX which has a similar package too.
@@_donny_9473 no problem! HMU if you're interested in learning more! this video is pretty old, and the tech is a lot more advanced since this video was released, I need to make a new one

I'd love to watch part 2
Where you at bro we miss you. How did this pan out?
Word! I wanna see this thing in real life
You're doing it right. You should come back and deliver cool video about generative design.
Dude! Did you do it? It's been 2 years!
You could set another restriction zone where one would be grinding. So the structure doesn't hang to low to the ground.

Yes absolutely! After I did this I ran it through FEA again to make sure it was still safe for use
Nice Paul, most trucks are made from alu, some magnesium, few titanium. I guess factoring in a steel axle you'd have some better results with alu

Hey, cool video. Can you do generative design for prescribed natural frequencies? E.g. long sheet structures.
I limit my intake to reduce my mass. After all, my intake is much larger in my exhaust.

Casting works but DIY solutions can be sketchy, make sure you get trained in how to do it first and practice q few times, not every shape is castable!

@@MrZomhad it is also possible to print this with some other metal printers like SLS and SLM Printers. there is not much rework needed in this way.
is possible to know the loads that you used for this project?
Hello paul ...may i get the boundry condition used for skateboard hanger design
How can we get it??
Hi, thanks for the video. Do you know if generative design could be used for natural frequency optimization?
short answer: not yet

where is the update ? Did you 3d print it and test the strength?
Is it possible to add a plane symmetric constraint so as iterations goes on it will keep the geometry symmetric ?
Came here to ask the same thing.
Hi am trying to find the add in for my mac and i cant find the add in
Hi Stefanos, it's PC only currently, it'll be coming to Mac very soon though!
hey will you be releasing the cad file for those trucks?
Did you ever print this and have any success?
yes! I made a whole video with Braille Skateboarding about it! search for "3d printed skate truck"

Where's the follow up bro? Did it work?
yup! just look up titanium 3d printed trucks right here on RUclips. I worked with the boys over at braille skateboarding to test them out!

Are you a fan of Macklemore?
Anything besides autodesk?? 😑
I mean... I work for Autodesk, so probably no lol
@@paulsohi9015 😅 Fair enough. All I see is autodesk stuff when I search this lol. Guess yall really got the market for this one!
