TPE is another good option for printing basketballs. It is similar to TPU in terms of flexibility and durability but offers even more elasticity. This makes it suitable for basketballs that require a higher degree of stretchability. However, TPE can be harder to print with, as it requires precise temperature control and print speed settings.
- Flexible Nylon
Nylon is known for its strength and durability, but in its flexible form, it also offers a certain degree of elasticity. While it is not as bouncy as TPU or TPE, flexible nylon can be used for specific parts of a basketball, such as reinforcing the ball’s structure.
- Flexible PLA
This flexible PLA is a patented formula that is softer than TPU filament. Balls 3D printed with it have better bounce than standard TPU 95A. It's the perfect filament for creating airless basketballs.
- Hybrid Filaments
Some manufacturers are experimenting with hybrid filaments that combine different materials to achieve the perfect balance between flexibility, strength, and durability. For instance, a mix of TPU and carbon fiber could enhance the ball’s performance by providing both elasticity and increased impact resistance.
How 3D-Printed Basketballs Work
3D-printed basketballs are reshaping the way we think about sports equipment. Unlike traditional basketballs, which consist of multiple materials (an inflated rubber bladder covered by leather or synthetic panels), 3D-printed basketballs can be designed and manufactured as a single unit.
