Nike has been granted a patent for a new footwear 3D printing process by the United States Patent and Trademark Office (USPTO). Pushing the boundaries of 3D printing and footwear customization, Nike is bringing athlete-grade shoes to the wider market. With an increasing appreciation for high-performing ergonomic design, Nike’s new sustainable process may become a game-changer in the footwear industry.

Nike’s commitment to personalization is evident in the procedure that focuses on detailing; each shoe can be tailored to meet the unique needs of individual athletes and now the larger public, enhancing both user comfort and shoe performance. The long-standing legacy of pioneering footwear technology is yet again revolutionizing the engineering of shoe manufacture through products like the iconic Nike Air, the ‘game-changing’ Vaporfly running shoes, and now the high-performing Flyprint technology. 

Nike’s 3D Printing Patent: Athlete-Grade Running Shoes for the Wider Market 

The ground-breaking procedure comes with several advantages for the user.

1. Meticulous personalization and customization
2. Enhanced strength and abrasion resistance
3. Lightweight material  with heightened flexibility vs. rigidity
4. Optimized support zones and personalized cushioning patterns
5. Zero adhesives, zero stitching
6. Sustainable product with reduced wastage

For the industry, the key element is a factor of doubled ease of manufacturing and the promise of mass production. Unlike traditional two-part shoe construction techniques, the new procedure first prints the digital design onto fabric material to create the shoe’s upper, and the sole is then 3D printed directly onto this unit, thus creating a monolithic shoe in one go. 

A piece of fabric (knitted, woven, or non-woven) is placed flat on a tray within the printer, and a chosen material (ink, resin, acrylic, polymer, or thermoplastic-based) is extruded directly onto it to render the desired pattern. Multiple layers can then be added as reinforcements to required areas to enhance strength and flexibility. A sock liner can also be added to the upper for a comfortable fit. After the first printing is done, the pattern is cured with UV light to enable strong bonding between the base fabric and the extruded material. The flat upper is then tuned into its final form. 

Now, the upper is placed upside down, and the sole is printed on top of it using (at least) one pre-determined three-dimensional pattern. The mid- and out -soles can be made from cushioned materials like polyurethane or foam rubber. The sole is also UV-cured, and the shoe is then set for quality checks.

Nike’s printing can also enable the creative production of hats, jackets, shirts, gloves, and a lot of other apparel made from fabric, leather, rubber, and foam. The patent boasts the fact that the new method is not limited to the footwear industry. For now, one can expect all types of personalized footwear — dress shoes, loafers, sandals, slippers, boat shoes, work boots, and a variety of sports footwear, including shoes for athletics, basketball, soccer, cycling, tennis, baseball, cross-training, and hiking. But, the implications of this technology go beyond just the athletic world. 

“We have control over every single line,” says Roger Chen, Nike’s senior director of digital innovation. “If someone says, ‘Hey, it’s too loose in the toe box,’ then I can go and add some additional lines without having to redraw the whole thing.”

Procedurally Performant Patterns

Led by David Burpee, a multidisciplinary Computational Design Leader from the PNW, the workshop “Procedurally Performant Patterns” takes participants through a singular workflow covering multiple aspects of computational design in products and footwear, from design to visualization and beyond, highlighting Houdini's combinatory power within these domains. By integrating performance data as an input to drive differentiation within pattern design, allowing patterns to adapt to various performance conditions, the aim is to go beyond geometry creation, providing insight into leveraging the interconnected environment of Houdini to create procedural textures for product visualization and animation purposes. 

In line with Nike's personalizing notion, the workshop is set to uncover a dynamic and flexible approach to leveraging the procedural design of performance-driven patterns in SideFX Houdini for footwear and industrial design applications. Ultimately, the workshop offers a deeper understanding of how computational tools can be used to generate customisable and parametric designs with performance-optimised patterns for footwear.

The History of Nike Air, Vaporfly, and Flyprint

From the revolutionary Nike Air cushioning system to the high-tech Vaporfly running shoes and the innovative Flyprint 3D printing technology, Nike has continuously pushed the envelope in footwear technology, especially for athletes looking to gain a competitive edge.

In 1979, Nike launched Nike Air. A revolutionary technology at the time, Nike Air uses pressurized air inside a lightweight, durable sole for superior cushioning. The system was an instant success, making it one of the brand’s most iconic features and setting a solid foundation for upcoming innovations in shoe design.

In 2017, the Vaporfly series was released. Using a carbon fibre plate in the sole, this model provided superior propulsion with reduced energy loss during long-distance running, making it an elite choice for marathon runners. Many athletes broke world records while wearing Vaporfly.

The same year, Nike took another leap forward with the introduction of Flyprint technology, marking the first use of 3D printing to create a shoe upper. The Flyprint series was the breakthrough that introduced data-driven designing and 3D printing technology into customized shoe manufacturing and pushed the envelope further to culminate in this latest, ground-breaking patent.

The Future of Footwear

The evolution of athletic apparel with Nike’s commitment to integrating technology through cutting-edge innovations signals that it could potentially be expanded to create highly customized sportswear, from performance-enhancing wear for athletes to individually customized athletic gear for everyday users in the near future. In-store customization options could be the brand’s next offer of a unique shopping experience. 

At a broader scale, the new 3D printing process is set to inspire innovations in manufacturing industries and force a shift toward more sustainable and personalized production practices. Fashion itself could be redefined to be more accessible and even cost-effective. A new era of fashion is here — where customers can not only design their own apparel but also have access to products that are tailored to their exact specifications of measurements and material. Nike’s latest move is just the beginning, and the possibilities for what comes next are endless.
