What You'll Learn
The science behind the bounce
The airless basketball, a groundbreaking invention by Wilson Sporting Goods, challenges this conventional mechanism. By employing 3D printing technology, Wilson has crafted a ball with a lattice structure composed of small, hexagonal holes. This design allows air to pass through the ball, eliminating the need for inflation and solving the issue of air escaping over time. The lattice structure, akin to a honeycomb pattern, is created using an elastomeric polymer, resulting in a ball that weighs approximately the same as a standard basketball.
The bounce of the airless basketball, according to Nadine Lippa, Wilson's lead engineer, comes from the ball's structure itself. The lattice design enables the ball to deform and store energy, similar to the compression and release of springs. This stored energy is then released, propelling the ball to bounce back up. The size of the bounce can be adjusted by altering the lattice design, making it either larger or smaller.
Another advantage of the airless basketball is its ability to mitigate the impact of environmental factors. In traditional basketballs, changes in elevation and temperature affect air pressure, influencing the ball's bounce. The airless design, however, provides a more consistent performance across varying environments, reducing the impact of home-court advantage due to elevation differences. This innovation levels the playing field, ensuring that players' skills are tested more than their ability to adapt to environmental conditions.
While the airless basketball offers solutions to longstanding issues, it also presents new challenges. The ball's unique structure and material composition result in a different feel to the hand, even though it bounces identically to a pressurized basketball. Players have developed a connection with traditional balls, understanding the force required to make a shot. The airless basketball's altered aerodynamics may require players to relearn their shooting technique to account for the different flight path the ball may take.

Air pressure vs lattice structure
Air pressure and lattice structure are two key factors that influence the bounce of a basketball. The amount of air pressure inside a traditional basketball affects its bounce. As air starts to escape, the pressure decreases, resulting in a reduced bounce. On the other hand, the Wilson Airless Gen1 basketball features a unique lattice structure that eliminates the need for air pressure.
The lattice structure of the Airless Gen1 basketball is created through 3D printing, forming a complex pattern of small, hexagonal holes. This design allows air to pass through the ball, preventing the issue of deflation. The lattice structure also provides a storage mechanism for energy, similar to the compression of springs. When the ball is deformed, it stores energy, and the subsequent release of this energy allows the ball to bounce back. The size of the bounce can be controlled by altering the design of the lattice.
While air pressure in traditional basketballs is crucial for bounce, it presents several challenges. Firstly, over time, air can leak out, causing a decrease in pressure and affecting the ball's performance. Secondly, environmental factors, such as elevation and temperature, can impact the air pressure. For example, at higher elevations, the reduced atmospheric pressure can result in a bouncier ball, giving teams at those locations an advantage.
In contrast, the lattice structure of the Airless Gen1 basketball provides a more consistent and durable solution. By eliminating the reliance on air pressure, the ball becomes less susceptible to environmental influences and temperature changes. Additionally, the lattice design enhances the ball's durability, as demonstrated by its resistance to aggressive conditions in testing.
The Airless Gen1 basketball, with its innovative lattice structure, offers a promising alternative to traditional air-pressurized basketballs. By addressing the challenges associated with air pressure, the Airless Gen1 aims to provide a consistent, durable, and high-performing basketball experience. However, it is important to note that players may need time to adjust to the new ball's feel and aerodynamics, which differ from those of traditional basketballs.

The impact of elevation
At higher elevations, the effect of gravity on air molecules decreases atmospheric pressure. This decrease in air pressure can impact the bounce of a traditional basketball, as it relies on internal air pressure to maintain its bounce. With every 1000 feet of elevation increase, pressure gauges will read 0.5 PSI higher. For example, the difference in elevation between Denver, Colorado (5280 feet) and New Orleans, Louisiana (3 feet) results in a notable disparity in air pressure, affecting the bounce of the ball.
The airless basketball, however, is not dependent on air pressure for its bounce. Instead, its bounce is derived from the deformation and energy storage capabilities of its lattice structure. This design feature ensures that the ball's bounce remains consistent regardless of elevation changes. This consistency in performance across different elevations is a significant advantage, as it eliminates the variable of environmental effects, allowing players' skills to be truly tested.
While the airless basketball addresses the issue of elevation, it presents a new set of challenges. The absence of air pressure can affect shooting and dribbling, requiring players to relearn their shooting techniques due to altered aerodynamics and flight paths. Additionally, the feel of the ball differs from traditional basketballs, which may disrupt the connection and familiarity players have developed with the standard ball.
Despite these challenges, the airless basketball's ability to maintain consistent bounce at various elevations is a remarkable achievement. It showcases how innovative design and manufacturing techniques, such as 3D printing, can revolutionize sports equipment. As additive manufacturing becomes more mainstream and affordable, we may see the airless basketball or similar innovations become more accessible and widely adopted.

The manufacturing process
Ideation and Design
The concept of an airless basketball was first imagined by Wilson Sporting Goods, who wanted to address the common issue of inflatable balls going flat over time. They aimed to create a basketball that maintained its shape and bounce without relying on air pressure. To achieve this, they collaborated with General Lattice, a computational design company, to create a lattice framework for the ball. This lattice design, resembling a honeycomb structure, serves as the framework of the ball, providing structural integrity and bounce without the need for inflation.
Material Selection
Wilson's lead engineer, Nadine Lippa, and her team spent years experimenting with various materials and manufacturing methods. They ultimately chose to use a customized elastic polymer developed in-house by Wilson. This polymer material offered the necessary elasticity and durability to withstand the rigours of the game while also addressing the issue of deflation.
3D Printing and Additive Manufacturing
The lattice structure of the airless basketball is created through industrial-level 3D printing, specifically the selective laser sintering (SLS) method of additive manufacturing. This process involves using lasers to fuse layers of polymer powder into the desired 3D design. The powder bed is swept across, and a laser etches a pattern in two dimensions. This process is repeated layer by layer until a three-dimensional shape is achieved.
Post-Processing and Finishing
Once the 3D printing is complete, the excess powder is removed from the ball. It is then sealed and dyed using a smoothing technique developed by DyeMansion. The ball undergoes rigorous testing at Wilson's NBA test facility in Ada, Ohio, to ensure it meets the performance standards of a traditional basketball in terms of size, weight, and bounce. The finishing touch includes adding the typical basketball grooves that shooters feel for, enhancing the overall grip and feel of the ball.
Prototyping and Refinement
The airless basketball underwent extensive prototyping and testing over several years. Nadine Lippa, the innovation manager at Wilson, led the team through countless iterations, with many samples breaking or failing to bounce properly. However, they persevered, and after five years of experimentation, they achieved success with the final product, dubbed the Airless Gen1.

The lattice design enables the ball to deform and store energy, similar to springs, which is then released to create the bounce. This bounce can be adjusted to be larger or smaller depending on the lattice design.
One of the primary advantages of the airless basketball is its durability. Traditional basketballs lose their bounce over time as air gradually seeps out, but the airless ball cannot deflate or puncture due to its unique structure. It has even been tested against aggressive conditions, such as being hit with a baseball bat, and has shown remarkable resilience. This feature ensures that the airless basketball maintains its performance and bounce over an extended period.
Additionally, the airless design addresses the issue of varying atmospheric pressure in different arenas. The change in elevation between two locations can result in a noticeable difference in air pressure, affecting the bounce of the ball and creating an uneven playing field. The airless basketball eliminates this variable, ensuring that players' skills are tested rather than their ability to adapt to environmental effects.
While the airless basketball introduces exciting possibilities, it also presents challenges. The ball's unique structure and material may affect its aerodynamics, requiring players to adjust their shooting technique. Furthermore, the ball's high price tag may limit its accessibility to those who can afford it, at least initially.
