3-D technology in the spotlight What do a team of engineers designing a racing car and a team creating sports shoes for Adidas, Nike or New Balance have in common? Besides their use of brainpower, both are increasingly incorporating 3-D printing into their production. Formula One racing has been interested in what 3-D technology has to offer for quite a while now. Additive manufacturing ideally meets the needs of its design firms, which have a voracious appetite for numerous, varied and complex prototyping in short timeframes. For the German sports equipment giant Adidas, the goal is to produce 100,000 designs in 2018. It’s moved out of the experimental phase, and they’re now using a suspension polymerization process for mass production. Besides the advantage of custom manufacturing, for producing accessories perfectly geared to every physiquefrom shin pads and mouthguards to helmets3-D printing has taken a new step forward by moving into series production of shoes, bicycles, golf clubs and skis.
