Reply to comment by BeardySi in NASA's "evolved structures" radically reduce weight – and waiting by Maxcactus

Your example is still post-machined. Usually grown then wired then machined. If you can just machine it, it’s probably faster depending on quantities.

Depending on how it’s designed, you might actually not be able to machine it due to inaccessible inner structures. It‘s not exactly time or cost-effective, though.

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!
