Metal Additive Manufacturing Assists Olympic Cyclists in Rio
Custom handlebars made with selective laser melting helped a team of cyclists from France earn a medal at the 2016 Olympic Games.
For cyclists at the top of their sport, having the right equipment matters nearly as much as physical conditioning. With its ability to provide strong yet lightweight parts, additive manufacturing has proven to be a valuable tool for building bike parts. A UK cyclist broke records riding with 3D-printed handlebars earlier this year, and we’ve reported on uses of AM for bicycling here and here.
A group of French cyclists competing in this year’s Olympic Games in Brazil were some of the most recent athletes to experiment with additively manufactured bike parts. Erpro & Sprint, a digital manufacturer based in France, partnered with the French Cycling Federation and GIE S2A to develop custom 3D-printed handlebars for each of the seven athletes to use in Rio.
The handlebars were designed by GIE S2A to be aerodynamic and ergonomic. Built from lightweight aluminum, the handlebars have an internal lattice structure to further reduce their weight while maintaining strength.
Erpro & Sprint produced the handlebars on an SLM 280HL metal 3D printer from SLM Solutions. The printer uses selective laser melting (SLM) to precisely melt metal powder using one or two fiber lasers. Watch them being made in the video below:

French cyclist Thomas Boudat debuted the 3D-printed handlebars at a race in Italy earlier this year, taking first place. The French men’s team sprint cyclists went on to win the bronze medal at the Olympic Games in Rio using the AM handlebars.
GIE S2A will bring the handlebars to the consumer market in late September as the JetOne range.
GE Additive’s Ehteshami says, “To make these parts the ordinary way, you typically need 10 to 15 suppliers, you have tolerances, you have nuts, bolts, welds and braces.” With additive, “all of that went away.” The helicopter project is a detail in a story worth knowing.
A bracket redesign has a lot to say about the successful application of metal AM. One of the takeaways: Support structures are worth the effort!
The largest high-pressure die cast tool builder in North America is 3D printing die inserts and water jackets for major automakers. It’s a tough sell, but one company is succeeding — and it’s just getting started.
