Awesome, complex manufacturing – for SPACE!
It’s starts as 7,000 lbs of raw material. It ends up a 148 lb part.

Aluminum Extrusion
Awesome video of aluminum extrusion in action!
What it sadly doesn’t show is actually stretching the aluminum after extrusion (which seriously blew my mind when watching it live on a FABtour).
It also doesn’t explain how to extrude hollow shapes.
