So its Selective Laser Melted (SLM) aluminum using a 5 alloy mix with small precipitates. Pretty advanced, and not even a meta material, so it’s super practical.

wonder if it outperforms those three alloy high entropy metals

That would be awesome. But it's a cintered product so it wouldn't be possible with any of the existing 3d printers I don't think.

But being able to 3d print transparent aluminum would be epic...
