The Titanium Spider Bracket with Optimized Lattice Structures
HTML-код
- Опубликовано: 23 авг 2024
- Altair, Materialise and Renishaw collaborated to successfully create a lattice structured spider bracket; a functional structure which is lightweight, robust and reminds biological lifeforms. The design for the spider bracket was generated using Altair OptiStruct®, prepared for printing with Materialise software Magics, 3-matic and the Build Processor, to be 3D printed on Renishaw’s AM250 metal additive manufacturing system.
Pretty incredible. This is the future of light weight parts.
We won the big aerospace contract to produce the spider bracket! They need five thousand units by next month. That won't be a problem, will it???
Strength to weight ratio compared to a more conventional bracket?
OK, so how is this different than Fusion 360's generative design AI? Is this even powered by a generative design AI?
You're not really talking much about the underlying algorithms.
Wait, does fusion 360 have one?
@Palatisan yes, Fusion 360 has introduced it as a new feature. They allow users to access their (Autodesk's) AI system called "Dreamcatcher".
I have tested it and it's interesting. There is, however, a somewhat steep learning curve because you have to specify parameters beforehand (how much material you want to use etc.). The algorithm then runs a couple of simulations and shows you a veriety of possible solutions of which you can pick your favorite.
The whole thing works on a subscription model: when you buy your license you get a specified amount of so-called "cloud credits" that you can use for your projects/simulations. I haven't used it much so I still have most of mine, LOL
But from what I can tell the feature that they show in this video is what we refer to as an aided topology optimization. The fact that they haven't responded to my comment confirms my suspicion.
Here is some more reading material on the topic:

@@yelectric1893 On paper, yes, for Marketing
@@AntonioKowatsch they haven't responded to your comment because they don't care about us that are not big companies that can allow the money needed to pay monthly fee that cost the license and because the only answer was from a year before yours so they just don't attend answers to old videos.
Talking about softwares, Hypermesh and Optistruct were the pioneers of topology optimization implementation on softwares, they don't use AI, is just well structure code. What Autodesk does is just a gimnick, is not AI, what it really does is a heuristic (also known as intuitive optimization, is known for showing you results that tend to ignore the needed parameters for the design) method for topology optimization were it produces a several amount of random alternatives and ends displaying the cutest design, not the optimal design.
Remember, not all products that are called "AI" are AI.
How does the process allow for greater than 45 degree overhangs? Would you be able to explain the 're coating' method @ 2:30?
Thank you for your question. Charlie from Renishaw helped us to answer your question. See here is answer:
"Bulkier areas of material do not cope well on top of unmelted powder, hence we need to use supports, and must adhere to the 45° rules. However, the more delicate the geometry is, the shallower we can build. As only a small
amount of energy is required from the laser to form these small structures, and it is more tolerant to forming on top of fresh powder. Our recoating mechanism is made from a silicone rubber which does not disturb the delicate structures."
Hi, thanks for the reply. Typically, when exporting a MTT file for printing, you will use all one laser setting for the whole build, meaning the same laser power for the shallow overhangs as well as the solid parts. How have you achieved to dynamically modify the lasers power and other parameters throughout the build? Is this through the materialise software only, or a have you also included additional hardware on the AM250. Thanks for your time.
They forgot to mention the price--LOL
oh for hell sake turn the background music OFFFFFFFFFFFFFFFFFFF
ITS so hard hearing the commentry with this playing
if i want to listen to music i go to youtube
use your common sense please
