Like an Olympian, additive manufacturing is progressively becoming faster, better, and stronger with growing pains in the process. From basketball to tennis, engineers are discovering a litany of ways to enhance sports and athletics with 3D printing. This article will showcase three exciting developments that show how additive manufacturing and sports are coming together to create a new era of performance.
What Makes Additive Manufacturing Appealing to Sports Manufacturers?
Let's preface the actual applications of 3D printing in sports today with a quick recap on how it works. 3D printers work by building objects layer by layer. This process starts with a digital 3D model, which is then sliced into thin cross-sections. The printer deposits material — typically plastic, metal, or resin — according to these cross-sections, gradually building up the object from the bottom up.
This layered approach allows for the creation of complex geometries that would be difficult or impossible to achieve with traditional manufacturing methods. It also enables on-demand production and facilitates the creation of highly customized products.
How Additive Manufacturing Makes Sports Faster, Better, and Stronger
This technology opens up a realm of possibilities in sports. Personalized equipment, made possible through additive manufacturing, allows for the creation of custom-fit gear tailored to an athlete's unique physiology. For example, a tennis player can have a racket grip molded precisely to their hand, or a cyclist can have a helmet that fits the exact contours of their head.
This level of customization extends to footwear, where 3D-printed insoles can provide optimal support based on an individual's foot shape and gait analysis. Even protective gear like shin guards or shoulder pads can be tailored to an athlete's body, ensuring maximum protection without sacrificing mobility.
Accelerated development cycles allow teams and manufacturers to quickly iterate on designs and test new concepts for equipment and apparel in record time. Enhanced performance through innovative designs is another key advantage. 3D printing allows for the creation of complex structures that can improve aerodynamics, reduce weight, or enhance strength. For instance, bicycle frames can be designed with intricate internal structures that maximize strength while minimizing weight, giving cyclists a competitive edge.
Sustainability is also a significant benefit. 3D printing can reduce waste by using only the necessary amount of material, and many 3D printing materials are recyclable. This aligns with the growing focus on environmental responsibility in sports.
Additive Manufacturing and Sports In Action
With the above advantages in mind, let's explore three exciting developments that showcase the intersection of 3D printing and sports:
Wilson Airless Basketball
Air-filled basketballs are far from the first thing that comes to most people's minds when they're asked to think about 3D-printable products. But according to market giant Wilson, air may not be necessary anymore. The company is pioneering a fascinating reinvention of the classic basketball using 3D printing technology. Their prototype 'solid' basketball features a lattice structure with hexagonal holes designed to mimic the bounce of traditional basketballs.
Through extensive testing and iteration, Wilson engineers seem to have come up with something with the familiar grip, and weight that players expect, all without the need for pressurized air. Imagine a world where flat basketballs are a thing of the past. No more fumbling with air pumps or worrying about losing pressure during a crucial game. It's an entire possibility with this new project, which with enough time and trial, could eventually hit major courts across North America.
Hayabusa Boxing Gloves
Boxing is a centuries-old sport with a chronic pain point - hand injuries. Traditional gloves, while effective, have limitations in their ability to absorb and distribute impact. Enter 3D printing technology, revolutionizing this ancient sport with a modern solution.
Hayabusa has developed a groundbreaking 3D-printed boxing glove that promises to redefine protection in the ring. Instead of conventional foam padding, these gloves feature a complex lattice structure made of resin. An intricate network of geometric cells works alongside a resin lattice structure to dissipate impact forces more effectively than traditional foam padding. By distributing the energy of a punch across a wider area, these gloves reduce the risk of localized trauma to both the wearer's hands and the opponent's body. The lattice design also allows for unprecedented customization. Boxers can now have gloves tailored to their specific fighting style, hand shape, and weight class.
While still in the testing phase, these 3D-printed gloves have garnered significant interest from professional boxers and trainers. If they prove successful in real-world applications, we could see a dramatic shift in boxing equipment standards in the years to come.
Ultralight AMbelievable Dampener

Tennis dampeners are meant to reduce vibrations and improve player comfort. Major sports stars from Novak Djokovic to Rafael Nadal use these small devices to enhance their game. Additive Appliances, an Italian startup, is asking the rhetorical question of whether dampeners themselves can be enhanced through additive manufacturing technology.
Their 3D-printed AMbelievable dampener leverages the unique capabilities of 3D printing to create a dampener with a complex internal structure that selectively absorbs vibrations across different frequency ranges.
The AMbelievable doesn't just dampen vibrations; it fine-tunes the player's experience. This allows players to fine-tune their racket's response, potentially enhancing their control and reducing fatigue during long matches.
Conclusion
From customized equipment to innovative training tools, additive manufacturing is revolutionizing how athletes perform and how fans experience the game. This technology is not just changing the way sports gear is produced; it's reshaping the very nature of competition itself.
Considering all of the other use cases currently being pursued in fields like aerospace, healthcare, and construction, it's clear that we're only scratching the surface of what's possible with 3D printing.
