Carbon fiber, aluminum, maybe the odd bit of titanium here or there: These are the materials we usually expect race cars to be made of. Now you can start adding thermoplastics like Ultem to the list. Additive manufacturing has become a real asset in the racer’s toolbox, although the technology has actually been used at the track longer than you might think.
"Some people think that 3D printing was invented last year," said Fadi Abro, senior global director of automotive and mobility at Stratasys. The company recently became NASCAR's official 3D printing partner, but it has a relationship with one of the teams—Joe Gibbs Racing—that stretches back two decades.
"Now the teams only have certain things that they can touch in the vehicle, but what that does is it makes it so that every microscopic advantage you can get out of that one tiny detail that you have control over is so meaningful to your team," Abro said.
