It's just a prototype for now, but the HRE3D+ 3D-Printed Titanium Wheel offers a glimpse at the future of high-performance rims. The wheel was developed by HRE in partnership with GE's AddWorks team and is the first to be crafted using Electron Beam Melting, a type of 3D-printing process. As opposed to a traditional aluminum Monoblok, which is made from a 100-pound block of aluminum in a process that removes 80% of the material, the EBM process removes only 5% of the titanium material, which also happens to be lighter, stronger, and more corrosion-resistant. The wheel was crafted in five separate sections, then joined using a custom center section and bolted onto a carbon fiber rim using titanium fasteners. The wheel will be on display at the Formnext trade show in Frankfurt, Germany, but no production plans have yet been announced.
