Yeah that’s my point. All the normal engineering steps apply for sure. Just some of them are made more difficult due to a complex shape instead of a beam.

Relativity Space, who are trying to 3d print an entire rocket, must be putting a lot of work into these problems…

There were talks about optimized casts for fractures. Like here:

r/generative
Basically, letting the computer fill spaces using some constraints. Artists love it. But also, for example, game designers (need to create a forest? Well, you could 3D model each tree, or create a generator that generates 3D models of trees...)

Knock knock knock
This is the department of homeland security! Your neighbor said you were building rockets in your garage!

This seems like really great technology that could have a big impact in other industries eventually as well. Maybe 20 years from now we'll start seeing bony iterated frames showing up in cars.

What an excellent post. I feel smarter already.

This paragraph and the resultant comments made me join your sub. That's some brilliant info!

NASA engineers are famous for their lack of ingenuity, also jets and rockets are totally the same problem space.

I think your confusing this tool as some panacea where engineering input is no longer needed. It’s not automating the whole design process. It’s just a tool for one part of it, all the additional concerns you have mentioned are part of the engineering process. If you have AI start dictating the requirements, inputs, and validation then yea that gets scary. This is just a design tool

But all of these considerations are also in play when you design something without the gen algo. This is just engineering lol

Reply to comment by tarkool in UCLA scientists, Dr. Eric Kang Ting and Dr. Chia Soo, in collaboration with NASA and the Center for the Advancement of Science in Space are performing experiments in space to test an experimental drug that could one day result in a treatment for osteoporosis. More in the comments. by tarkool
Also, for those people who are more scientific minded and want to read more about NELL-1, an osteoinductive protein, here are some links to the scientific articles that go more in depth into the research done by Dr. Eric Kang Ting and Dr. Chia Soo and their team:

All of that can easily seen and detected. This is high end manufacturing, not someones at home printer.

Indeed. The real benefit of printed parts is you can make geometries that are not possible to machine.
Plus, I dread to think of the time and cost involved in machining that kind of thing out of a 250x250x400 titanium billet. Not many have NASA'a deep pockets!

This. Design optimisation is design optimisation however you get there.

Where's the intelligence in genetic evolution? Intelligence is an outcome of evolution, not part of it.

Funny, at my last job I was literally developing and building a pseudo printer that would be used to determine a process for testing this very thing. In a nutshell, this device would function similarly to a metal 3d printer but it would very accurately weigh every single layer to calculate bulk density of the powder and through laser scanning methods look for potential voids in each layer. The idea is that it would be used as a metric for honing in on 'best practices' for optimal printing.

What's incorrect about the parent post?

3D printed metal has limitations that machined parts don't when it comes to strength. It has gotten better, but it still is not as good.

Man I love living in the future. I wonder how they are able to account for possible issues with micro-cracks at the edge of the channels inside the closed object. Just normal x-ray?
