Arthur C. Clarke’s third law of futurist writing states, “Any sufficiently advanced technology is indistinguishable from magic.” HRE’s new 3D-printed titanium concept wheels very nearly fall under that definition. 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, allowing the wheel company to create a design that wouldn’t be possible through traditional manufacturing methods like CNC machining alone. Here’s how it works. 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 […]
