This isn't the type of wheels that I like, but it's pretty impressive. I've been doing all of the 3D printing at the GE plant where I work, and I also work with titanium, so I can understand how the process works to make something like this. GE is very big in 3D printing jet engine parts, which could eventually eliminate most of my job as a toolmaker.
