What You'll Learn
3D printing technology
The world's first 3D-printed airless basketball was developed by Golden Eagle for Wilson Sporting Goods. Dr. Nadine Lippa, Wilson's manager of basketball R&D, led the project. Lippa and her team spent five years finding the right combination of material properties and mechanical design for the airless basketball.
The basketball features a sleek 3D-printed lattice structure made from an elastic polymer. The surface of the ball is designed with small hexagonal holes, similar to a honeycomb, which allow air to pass through freely. This lattice structure is what gives the ball its bounce. When the lattice is deformed, energy is stored and then released, allowing the ball to bounce back. The ball has roughly the same weight as a standard basketball and bounces identically to a pressurised basketball, although it feels different to the touch.
The 3D printing technology used to create the airless basketball allows for on-demand printing, reducing excess product and lowering the carbon footprint of manufacturing and shipping. The ball's unique design also eliminates the need for an air pump or needle, as it does not require inflation.
While the exact materials used in the basketball have not been disclosed, it is believed to be a mixture of something "squishy and bouncy." Some have speculated that it is made from a high-impact thermoplastic elastomer powder material, while others have suggested TPE or PEBA.

Selective laser sintering
The SLS process begins with a Computer-Aided Design (CAD) model, which defines the precise geometry, size, panel configuration, and surface texture of the basketball. The chosen material must balance strength and flexibility to achieve the desired bounce and durability.
Once the CAD model is generated, SLS is employed to deposit the chosen material layer by layer, gradually building the spherical form. In the case of the Airless Gen1 Basketball, Wilson used lasers to fuse layers of polymer powder into the 3D design. This process was repeated until the entire sphere was formed.
The use of SLS allows for the creation of complex structures, such as the lattice design of the Airless Gen1 Basketball, which lets air pass through the ball. This structure also contributes to the ball's durability, withstanding aggressive conditions such as being hit with a baseball bat.
The final steps in the SLS process include removing the 3D design from the surrounding excess powder, sealing it, and dyeing it black. The result is a basketball that matches the performance of a standard basketball, providing the necessary resilience and elasticity without the need for inflation.
