3D3DBlisk (Bladed Impeller Disk).
This is a fabulously beautiful cast titanium jet engine part. It's titanium rather than nickel super-alloy like the turbine blades I have under nickel because it is part of the intake system, not the combustion or exhaust systems. So it's subject only to incredibly high stresses, not ridiculously incredibly high stresses like the post-combustion parts of the engine.
Imagine how complex (and expensive) the molding and machining of this part must be! But beyond its technical beauty is its aesthetic beauty: Only the smallest fraction of artists can ever hope to create an object of this depth and wonder.

I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
