Pictured above is the FEA of both halves of steering wheel made out of aluminum
Conclusion:
Creating a steering wheel with both halves made out of aluminum would be unnecessarily strong, heavy, and be far too time consuming to produce. Alternatively, from the FEA we can see that a steering just made out of ABS would be far too weak to withstand the necessary forces. Additionally, we can see that if the steering wheel was only a back half made out of aluminum, that it would be strong enough. Therefore, based on the results of the FEA we decided to make the steering wheel back half be machined out aluminum and the front half be 3D printed out of ABS.
