What You'll Learn
The ball is made using 3D printing technology
The world's first 3D-printed airless basketball, the Airless Gen1, was created by Dr. Nadine Lippa, the principal materials engineer for Wilson Sporting Goods, in collaboration with the University of Southern Mississippi. The ball is made using 3D printing technology, which allows for the creation of basketballs with millimetre precision and customisable features. This means that each ball can be tailored to the needs of individual athletes or teams in terms of size and weight.
The 3D-printed basketball is produced using a 3D printer that deposits layers of plastic material to form the ball's structure. This structure is a lattice of small, hexagonal holes, resembling a honeycomb. The lattice design allows air to pass through freely and contributes to the ball's bounce. The lattice structure can deform, storing energy like a spring, which is then released as the ball bounces back. This unique structure eliminates the need for an air chamber, as in traditional basketballs, and maintains the ball's elasticity and bounce over time.
The material used in the 3D printing process is crucial to the ball's performance. The Airless Gen1 is made from an elastic polymer, specifically a high-impact thermoplastic elastomer powder material. This gives the ball its highly elastic and durable properties, ensuring greater resistance to wear and tear compared to traditional basketballs. The use of advanced materials, such as TPU or TPE, enhances the ball's performance and durability.
The 3D printing technology also offers sustainability benefits by reducing the carbon footprint associated with manufacturing and shipping. With no need for inflation, the airless basketball simplifies the playing experience and eliminates common issues related to air pressure loss. This innovative design challenges convention and offers a unique playing experience, although some players may need to adjust their shooting technique due to the different feel of the ball.
The development of the Airless Gen1 basketball by Dr. Lippa and her team is a testament to their perseverance and creativity. It showcases the potential of 3D printing technology in sports equipment design, paving the way for further innovations that will shape the future of sports.

It's made from an elastic polymer
The airless basketball is made from an elastic polymer. This innovative design was developed by Wilson's manager of basketball R&D, Nadine Lippa, who holds a PhD in sports and high-performance materials.
The basketball is created through 3D printing technology, specifically selective laser sintering (SLS), which forms the ball layer by layer until a complete sphere is formed. This manufacturing process results in a unique, highly elastic material that feels different to the touch compared to a traditional basketball.
The surface of the airless basketball is a lattice structure consisting of small, hexagonal holes, resembling a honeycomb pattern. This complex shape and material composition allow the ball to be nearly silent during play and eliminate the need for inflation, as air can pass through the holes freely.
While the exact chemical formula for the polymer has not been disclosed by Wilson, it is described as "squishy and bouncy" by reviewers, contributing to the ball's bounce and durability. The use of elastic polymer in the airless basketball also has potential sustainability advantages over traditional basketballs, as it does not require the use of pumps or needles and may prove to be a more "green" alternative.
Although the airless basketball offers these benefits, it is important to note that it differs significantly from the classic leather feel of traditional basketballs, and some players may prefer the familiar texture and sound of the conventional ball.

The surface is a lattice of small, hexagonal holes
The surface of the airless basketball is a lattice of small, hexagonal holes, resembling a honeycomb. This unique structure is made possible by 3D printing technology, specifically selective laser sintering (SLS), which forms the ball layer by layer until a complete sphere is created. The lattice design not only contributes to the ball's distinct appearance but also influences its bounce and durability.
The small hexagonal holes allow air to pass through freely, resulting in a ball that performs similarly to a traditional basketball in terms of weight, size, and bounce, without the need for inflation. This airless quality eliminates the need for an air pump or needle, allowing players to simply pick up the ball and play without any additional preparation.
The lattice surface of the airless basketball is created using an elastic polymer, contributing to the ball's overall elasticity and unique feel. While the exact chemical formula remains undisclosed by Wilson, the material is described as "squishy and bouncy." This elasticity is a key factor in the ball's ability to mimic the bounce of a pressurised basketball while offering a different tactile experience.
The hexagonal holes also contribute to the ball's overall weight. The Airless Gen1 basketball weighs around 610 grams, slightly under the maximum weight of 620 grams for a regulation basketball. This weight is achieved through the strategic use of the lattice structure and the chosen elastic polymer, ensuring that the ball performs similarly to a traditional basketball while offering a new playing experience.
The lattice surface of the airless basketball is a testament to the innovative use of 3D printing technology and material science. By utilising a complex lattice structure and carefully selected materials, Wilson has created a basketball that challenges the traditional design while maintaining the familiar performance characteristics that players expect from a basketball.
