A prototype basketball that could revolutionize the sport and featured in last weekend's NBA All-Star dunk contest was built in Pflugerville.
Driving the news: The 3D Airless Prototype Basketball, designed by Wilson Sporting Goods Co., was made just north of Austin, at the lab of 3D printing company EOS.
- The ball looks like a giant black Wiffle ball.
- Houston Rockets star K.J. Martin used the ball in the contest — but didn't win.
Why it matters: Basketball pickup players everywhere could soon avoid annoying pre-game conversations about which ball has the right amount of air.
What they're saying: "The quality control was mind-blowing," Jon Walker, business development manager at EOS, tells Axios.
- The company traditionally works with automotive, aerospace and medical device companies to build everything from rocket components to hip replacements.
- EOS sent a ball a day to Wilson's test facility in Ohio, and received daily feedback about its bounce, roll and roundness.

How it works: A laser sweeping across a powder bed, over and over again in an etch-a-sketch fashion, builds up the basketball, Nadine Lippa, innovation manager at Wilson, said in a video.
- Even something as small as adding a logo to the ball could change its mass distribution.
- Because it's a ball, "you're trying to get something to uniformly respond in all directions in the same way," Dave Krzeminski, a consulting engineer at EOS, tells Axios.
Context: Spalding offers a "NeverFlat" model — but, per the company's description, it's good for a year.
- The new Wilson model can't deflate because there's no closed-off inside space.
The challenge: Building a basketball that's truly playable, with that just-right bounce — a journey that took Wilson years as it sorted through material combinations.
- The ball, comprised of black see-through lattice, nearly fits the performance specifications of a regulation NBA basketball including its weight and size, per Wilson.
- "Once I actually saw the ball in person, it was crazy," Martin told Forbes. "I didn’t expect a basketball with holes to bounce and feel like a normal leather basketball."
Between the lines: The basketball is almost silent while it's dribbled, Krzeminski says.
- For proprietary reasons, EOS would not disclose the material used in the ball except to say it's made of an elastomer.
What's next: Lippa, the Wilson innovation manager, tells Axios she is "confident" the airless ball will be available to the general public "in the next year or so."
