Adidas and 3d printing

DATA-DRIVEN 3D PRINTED PERFORMANCE TECHNOLOGY DESIGNED TO MOVE YOU FORWARD

Today we are unveiling the next step in data driven 3D printed midsole innovation, the adidas 4DFWD. Combining years of athlete data with the unique technology of 3D printing, adidas 4DFWD is created to provide runners with an all-new running experience.

For over four years, we have developed 4D lattice midsole technology in partnership with Carbon. Combining athlete data and Carbon’s Digital Light Synthesis^TM technology to produce precision tuned 3D printed midsoles. adidas 4D footwear is amongst the first in the world to use this cutting-edge technology which offers the ability to fine tune midsoles to specific patterns of movement, so that athletes can enjoy precision performance with every step.

Born from this process is the new adidas 4DFWD lattice midsole. Identified from one of five million possible lattice structures and made of 40% bio-based material, the bowtie-shaped FWD CELL has been specifically coded to compress forward upon vertical impact. When compared to previous generations of 4D midsole, adidas 4DFWD generates three times as much forward motion under vertical loading in mechanical testing conditions. As a result, peak braking force experienced by the athlete during running is reduced by 15% as the midsole redirects these vertical impact forces into horizontal forward motion – delivering running economy comparable to that of Ultraboost midsoles in lab conditions.

adidas 4DFWD was tested through a range of bio-mechanical testing procedures at the University of Calgary, which analysed specific areas such as forward motion, braking force and running economy. The concept was also tested extensively with adidas runners local to the creation team in Germany and a carefully selected cohort of high-level running creators across the USA. Furthermore, cutting edge cognitive perception testing was carried out at Arizona State University.

4D technology provides us with the opportunity to design in a way that conventional foam midsoles do not allow. We took inspiration from the first generation 4D lattice midsole and set ourselves the challenge to take it to the next level. Coding millions of potential lattice structures to see if we could specifically design to counter negative mechanical forces experienced during running.
Working closely with Carbon, our product teams, and testers we identified one perfect lattice midsole that is designed to compress forwards under loading and counter mechanical forces whilst delivering a unique gliding sensation for our runners.

Complementing the adidas 4DFWD midsole is a new PRIMEKNIT upper made from recycled polyester. Providing runners with a super-lightweight premium upper that encases the foot in a seamless sock-like fit. Historical mapping data has been used to code the PRIMEKNIT upper to perfectly align with the unique properties of the 4DFWD midsole. Helping to give runners all the support and comfort they need whilst on their run.

At adidas, we’re always looking to combine athlete insights with new and innovative technologies to create the best performance running products. With this approach, we aim to serve and to delight different runners with diverse experiences depending on their needs, being it to run faster, or to achieve personal goals, or to run for longer, or to feel more comfort, always bringing new valuable benefit that runners can feel.
This industry first midsole innovation positions adidas 4DFWD as our most advanced digitally printed running midsole yet and showcases the potential of 4D technology in turning physics and bio-mechanic studies into performance solutions. We cannot wait for runners to feel and experience this new product that will deliver new and exciting sensations.

Carbon and adidas Collaborate to Upend Athletic Footwear

adidas and Carbon are creating the next breakthrough in athletic footwear, leveraging the Carbon Digital Light Synthesis™ (Carbon DLS™) 3D printing process to bring a new product and platform to life: Futurecraft 4D. Together, we are developing the first mass-production process that makes previously impossible midsole geometries with revolutionary 3D-printable materials, paving the way for custom, high-performance shoes that meet the unique needs of each customer.

In close collaboration with the Carbon team, adidas is leveraging the Carbon DLS process and EPU 41 3D printing material.

adidas continues to challenge the industry with its relentless focus on innovation to improve the performance of athletic apparel. But their latest idea—creating shoes with variable properties across the midsole to improve shoe performance for different sports—presented a difficult hurdle. Midsoles cannot be injection or compression molded in one piece with properties that vary across the part. Although they can be assembled from multiple parts through a labor-intensive process, this introduces multiple potential points of failure. Confronted with this challenge, the adidas team shifted its focus to the possibility of 3D printing midsoles to unlock the design freedom needed to enhance shoe performance.

3D printing has previously been used mostly to prototype products in development before they were produced with traditional manufacturing techniques. 3D printers are generally not designed for manufacturing scale. Prints are often painfully slow, require wasteful part supports that are ultimately thrown in the trash, and use materials that are vastly inferior to those used for production, resulting in weak and brittle parts. For adidas, the 3D printing industry lacked the production-grade elastomers needed for a demanding athletic footwear application. As a result, while adidas could 3D print prototypes of their midsoles, the final midsole design was still constrained by the ultimate production process, i.e. injection and compression molding. To overcome this constraint and 3D print final midsoles, adidas turned to the Carbon DLS process, its factory-ready 3D printing method, and its high-performance materials to design and directly produce the next generation of athletic footwear. A trailblazing partnership had been forged.

“With Digital Light Synthesis, we venture beyond limitations of the past, unlocking a new era in design and manufacturing. One driven by athlete data and agile manufacturing processes. By charting a new course for our industry, we can unleash our creativity — transforming not just what we make, but how we make it.”
Eric Liedtkeadidas Group Executive Board Member Responsible For Global Brands

Carbon’s rapid product development process enabled adidas to iterate over 50 different lattices for the midsole before landing on the current design. Traditionally, product development has followed four steps: design, prototyping, tooling, and production. This process is so slow that many product development programs can only afford three to five redesign cycles before finalizing the design, constraining the product team’s innovation. The Carbon-adidas collaboration made ten times as many iterations possible! Further, each iteration was produced with the same process and material as the ultimate product. These were not just prototypes for assessing a design’s visual appeal: We could actually test midsole performance in the design stage. In other words, Carbon’s technology makes prototyping obsolete. Gone are the days when it was necessary to prototype a product using a technology that does not allow for scale-up.

Motivated to enable the best production solution possible for adidas, Carbon established an incubator factory at its headquarters to develop and validate a print method and materials for Futurecraft 4D. In the incubator factory, Carbon developed a full print and post processing solution and validated it even before the equipment landed at adidas’s factory. It allowed the teams to closely collaborate throughout the shoe iteration process to ensure that the ultimate design was the best combination of design, material, and print process.

Having developed production ready printers and materials, Carbon was finally obliterating the barriers to using 3D printing for manufacturing real products at scale. Leveraging our programmable liquid resin platform that uses light to set the shape and heat to set the mechanical properties, the Carbon team developed a proprietary print strategy for midsoles that enables printing with essentially zero support material. This not only saves on raw material costs, but also dramatically reduces manual post-processing steps of traditional additive manufacturing.

Moving quickly and gathering feedback with every iteration, the Carbon team developed a revolutionary elastic material for the Futurecraft 4D midsole. adidas needed to 3D print lattices in a stiff but resilient elastomer to create a high performance midsole with excellent energy return. Carbon’s EPU 41 was the only 3D printable material that came close to the requirements for this application. When launching the collaboration, our teams realized that in order to make the shoe of the future, we needed to take what was already an incredible material and push the boundaries even further. Working closely with adidas to understand the use cases, the Carbon team iterated over 150 different material formulations to achieve the desired mechanical properties. The team also fine-tuned the color of the material to match the signature linen-green color of the launch shoe chosen by adidas’s amazing design team.

Carbon enables the design and immediate production of products, eliminating the conventional prototyping and tooling steps of a traditional product development cycle. This new production process has already allowed adidas to put a new shoe design in front of select athletes to better understand customers’ needs around Futurecraft 4D and, ultimately, to craft a better performing shoe. The process enables adidas to print previously impossible designs without labor intensive and complex assemblies. It has also opened up the ability to create optimal designs relying on software to simulate the production and use of athletic footwear. An industry leader with exceptional sport-science expertise, adidas will be able to use this production process to craft custom shoes with an ultimate performance uniquely tuned for each customer.

Nike and Adidas are testing 3D printers to create sneakers reports The Financial Times.

3D printing is used to transform digital drawings into physical objects, using molten plastic, metal and even wood to create solid shapes. Shoe manufacturers are introducing technology to create studded soles for football boots and running shoes.

Innovations in the field of sports shoes usually refer to the production of soles. Polyurethane air-filled cushioning technology has been used in the Nike Air Max line since 1987. And last year, Adidas introduced the Energy Boost line of running shoes, which have a solid granular thermoplastic outsole.

According to Nike Chief Innovation Officer Shane Coatsu, 3D printing has accelerated the development of the Vapor Laser Talon series of boots for professional American football players. “In six months, we managed to complete 12 prototyping cycles, and we fully tested them. As a result, we managed to significantly improve our product,” the FT quotes him.

Traditional sole molding techniques pour molten plastic into a metal mold, so Nike typically modifies parts of the sole, such as studs, every few years, Coatsu said.

Adidas has reduced the time it takes to evaluate new prototypes from four to six weeks to one to two days, Adidas said. Before the introduction of 3D printing, 12 specialists worked on the creation of prototypes in the company, but now the process of creating prototypes is controlled by only two technologists.

Shoe manufacturers have yet to reveal the cost of the 3D printed sneakers. So far, new shoe lines have not been introduced to the mass market either. However, the use of 3D printing technology can be in demand for individual tailoring of shoes.

The leading manufacturers of 3D printers are the German EOS, the American 3D Systems, and the American-Israeli company Stratasys, whose clients, in addition to Nike and Adidas, are Reebok, New Balance, Under Armor. A prototype of a home 3D scanner was introduced in March this year by MakerBot.

According to Stratasys marketing manager Bruce Bradshaw, 3D-printed footwear for the general public is still a long way off, but it will certainly be launched. The main obstacle to this so far is the printing time. According to him, it takes about two hours to produce one sole.

“We're not interested in the amount of production we can achieve, but in the speed with which we can make changes,” Coatsu concluded.
