Take a look at how HRE made its 3D-printed titanium wheels
Now imagine how long it'll take to clean them.

HRE Wheels announced this week that it teamed up with GE Additive to create the HRE3D+ concept wheel.
This wild design, which has spokes going through other spokes, was created using 3D-printed titanium.
This allowed the wheel company to create a design that wouldn't be possible through traditional manufacturing methods, like CNC machining, alone.
The wheel was created from titanium powder and a type of 3D printing called electron beam melting.
An electron beam generates heat, which is used to form the powder into metal structures in a vacuum.
Titanium likes to react with oxygen, so the vacuum bit is especially important.
This technology can make more than wheels -- it's being investigated for use in both medical-implant and aerospace manufacturing.
HRE and GE Additive created the wheel in five distinct sections comprising the face of the wheel.
Those five pieces were combined with a custom center section, all of which was eventually bolted to a carbon-fiber wheel rim using titanium fasteners.
