The first all-inconel can I'm aware of was the 3-d printed jobbie from Thermal Defense Solutions. They claim its baffle design was ginned up by computer modeling on a supercomputer by Oak Ridge national labs. So they naturally claimed it was the quietest and most sophisticated design in existence.



It bears more than passing resemblance to AAC's baffle, which was regarded as the best design in use. I don't see any "clipping," which was one of AAC's key features, but maybe that means AAC's wasn't the best design after all.
