What number of instances has a recreation of basketball been thwarted by a ball that was too flat to bounce? An air pump with a correctly sized needle isn’t one thing most individuals carry round with them on a regular basis, so Wilson has been working to redesign the basketball with a prototype that’s coated in an intricate sample of holes however by no means goes flat.
Though calling the basketball “airless” is a little bit of a misnomer given air remains to be capable of cross proper by means of it, it’s the most typical time period that’s been used to explain this know-how that replaces the necessity for pressurized bladders in objects designed to bounce or take in impacts.
Earlier than Wilson introduced the know-how to the court docket, corporations like Bridgestone have been working to create airless tires for autos, which first debuted 12 years ago at the 2011 Tokyo Motor Show on a tiny single-seater car. As a substitute of needing to be always pumped stuffed with air to supply a cushty journey for passengers, Bridgestone’s airless tires use a series of plastic resin spokes that may deform to soak up impacts however nonetheless permit a wheel to take care of its form so it could roll.
It’s been a gradual rollout for Bridgestone’s airless tires, nevertheless, which have largely been used on ATVs, some army autos, and bikes, to this point. Though the know-how is promising, making airless tires which are secure and appropriate for all types of terrain and climate—together with snow—has been difficult. Basketballs, by comparability, don’t have to help a sedan full of individuals cruising down the street at 80MPH, and balling within the snow is rarely a necessity.
Wilson partnered with a company called EOS which focuses on the usage of 3D printing for industrial makes use of together with medical and aerospace functions, to fabricate the unorthodox basketball design that’s coated in a sample of open hexagons as a substitute of sealed leather-based panels.

EOS relied on additive 3D printing know-how which, as a substitute of increase layers of extruded melted plastic, makes use of a powdered resin that’s hardened by a laser to create ultra-thin stacked layers with much more element. The result’s a completely hollow basketball that just about matches the “efficiency specs of a regulation basketball, together with its weight, dimension and rebound (bounce).” The 3D-printed ball may even be dyed in numerous colours, with the prototype being made all-black for its debut in the course of the 2023 NBA All-Star Sport festivities this previous weekend.
The NBA presently doesn’t have any plans to change to Wilson’s 3D-printed airless basketball design, however that doesn’t imply it’s a failure. Wilson plans to proceed to develop and enhance its design. And even when it by no means finds its method into the NBA, it might nonetheless assist make the sport extra accessible on playground courts throughout the nation the place pick-up video games won’t ever need to be canceled as a result of nobody can discover a pump to repair a flat ball.
