Collaboration with EOS for manufacturing

To bring the airless basketball to life, Wilson partnered with EOS, a leading manufacturing company specializing in additive manufacturing technologies. The selective laser sintering (SLS) method was employed to produce the basketball. This process involves using lasers to fuse layers of polymer powder together to create the desired 3D structure. The excess powder is then removed, and the ball is sealed and dyed black. The collaboration between Wilson and EOS enabled the production of a basketball that not only looks and feels like a traditional ball but also performs at the same level. The advanced manufacturing techniques employed in the process ensured the production of a high-quality and durable airless basketball.

Creation of the ball’s lattice structure

The most distinctive feature of Wilson’s airless basketball is its lattice structure, which allows air to circulate through the ball. To create this structure, Wilson developed a specialized elastomeric polymer capable of withstanding the demanding conditions of basketball gameplay. The lattice is composed of hexagonal holes that facilitate air circulation while maintaining the integrity and structural integrity of the ball. This innovative design ensures that the airless basketball bounces predictably, providing a consistent and reliable performance.

Challenges in achieving the desired bounce

Developing an airless basketball that replicates the bounce properties of traditional inflated balls posed several challenges for Wilson. One of the primary challenges was ensuring that the airless ball rebounded to the expected height without relying on air pressure. Traditional inflated basketballs utilize air pressure to generate rebound. Wilson’s engineering team worked diligently to create a ball that mirrored this performance characteristic while being entirely airless. Through extensive testing and development, they were able to overcome this challenge and produce an airless basketball that delivers the desired bounce similar to traditional inflated balls.

Testing for durability and damage resistance

Durability and damage resistance are critical factors in the design of any basketball. Wilson subjected the airless basketball to rigorous testing to ensure its durability under various playing conditions. The ball was not only tested for regular gameplay but also subjected to aggressive conditions, such as being struck with a baseball bat. Surprisingly, the ball demonstrated exceptional resilience, withstanding the impact without sustaining significant damage. This robustness makes Wilson’s airless basketball a reliable choice for athletes, as it eliminates concerns related to deflation and damage caused by external forces.

Advantages of an Airless Basketball

The introduction of Wilson’s airless basketball offers several distinct advantages over traditional inflated basketballs. By eliminating the need for inflation, the airless basketball eliminates the risk of deflation during gameplay. This removes the need for players to constantly check and adjust the ball’s pressure, allowing for uninterrupted gameplay. Additionally, the airless design ensures a consistent bounce, unaffected by changing environmental conditions or temperature fluctuations. Inflated basketballs often experience contraction when subjected to cold environments, leading to compromised performance. Wilson’s airless basketball addresses this issue, providing reliable bounce properties in all playing conditions.

Resistance to contraction in different environments

Traditional inflated basketballs are susceptible to contraction when exposed to cold environments. The contraction of air within the ball causes it to appear and play as though it is deflated. Wilson’s airless basketball overcomes this constraint by utilizing its robust lattice structure to maintain its shape and bounce properties, regardless of the environment. This resistance to contraction ensures consistent gameplay and performance, irrespective of temperature variations.
