The above image may look like a piece of modern art, or perhaps the digestive system for a robotic man – but it is in fact parts for a 3D-printed titanium bicycle frame. Renishaw, an additive manufacturing firm based in the U.K., has joined forces with Empire Cycles to build a one-off titanium MX-6 mountain bike.
Empire Cycles already offers a production version of the bike but in aluminum, yet it has been long noted that titanium has a high Ultimate Tensile Strength (UTS) that is far greater than aluminum. One issue has been that titanium is also denser than aluminum, so the parts had to be altered and material not contributing to the overall strength removed.
Titanium is a perfect metal for 3D printing as it isn’t a traditional ore, and it now appears that the bike industry is looking to get rolling on this technology. The future could be printed bikes that can be faster to produce and likely even more affordable for the rider.
