HRE is always good for some pretty technically impressive wheels. These new 3D-printed titanium wheels are something else. While 3D-printed wheels aren’t exactly new, 3D-printing a titanium wheel is. How HRE gets it done is impressive and the final result is stunning.

Using EBM (Electron Beam Melting) melting uses an electron beam to melt fine layers of titanium, which are then built up, one at a time, to create the final design. This process helps create incredibly complex shapes, shapes that would be impossible in traditional manufacturing.

For you techie nerds that like to watch impressive manufacturing (such as myself), HRE has provided a video that shows the process and the development of the wheel and it’s remarkable. The crazy shapes and geometric patterns that are possible from additive manufacturing (3D printing) versus traditional forging or casting are flat-out awesome.

What’s interesting is how the material looks. It’s gritty and rough and needs to be polished. Once polished, it looks like a normal machined wheel but it looks awesome with some surfaces polished and some showing the raw material.

At the moment, the HRE3D+ wheels have to be developed in multiple pieces and then bolted together. However, advances in additive manufacturing, as well as 3D-printing machines increasing in size, will allow HRE to create entire wheels in one piece using this same method.

We’re already big fans of HRE but we can’t wait to see these wheels in person. It must be said, though, that HRE isn’t planning on selling these just yet, as the HRE3D+ wheel is just a design and manufacturing concept to show what the brand can do. They have our attention.

Hmm, one of those items where I am caught between thinking 'cool' & 'No way'.

One thing is for sure...
Cleaning will be a royal PITA.

Cadmium Plating Steel Tools - basically Cadmium plating should not be used on titanium parts, and cad plated parts should not be used in contact with titanium parts.

Titanium is embrittled by cadmium from room temperature up.

So once you have bought your very expensive 3D printed titanium wheels, be very careful what you use to screw them on :)
