HRE states:
The "HRE3D+" is the result of an intensive design collaboration between HRE Wheels and GE Additive. The two companies worked together to push the boundaries of what is possible to create the first 3D-printed titanium automotive wheel.
Here is how this design process stands out:
With a traditional aluminum Monoblok wheel, 80% of material is removed from a 100-pound forged block of aluminum to create the final product. With additive manufacturing, only 5% of the material is removed and recycled, making the process far more efficient. Titanium also has a much higher specific strength than aluminum and is corrosion resistant, allowing it to be extremely lightweight and to be shown in its raw finish.
There was an intensive design collaboration between the Vista, California based team at HRE and the
GE AddWorks team out of Ohio. Using design queues from two existing models of HRE wheels, the
two companies worked together to create a stunning example of what is possible with additive
manufacturing. The wheel was produced on two Arcam EBM machines - Q20 and a Q10 in five
separate sections, then combined using a custom center section and bolted to a carbon fiber rim using
titanium fasteners.
