China3D printingNet October 11th, German sportswear brand Adidas (Adidas) revealed the “ultimate” 3D printingRunning shoes Futurecraft “STRUNG”.
STRUNG sneakers adopt3D printingThe latest Futurecraft insole produced by the machine manufacturer Carbon is made using the “industry first” textile printing process. Adidas’ new data-oriented approach to running shoes combines software and robotics technology to accurately place each line, so that shoes can be modeled based on the precise contours of a single runner’s foot.
“Futurecraft 3D is a prototype, an intention. We used a unique combination of process and materials in a completely new way.” Adidas Executive Board member Eric Liedtke said, “Our3D printingThe midsole not only allows us to make excellent running shoes, but also to use performance data to drive a truly tailored experience to meet the needs of any athlete. “
Adidas’ wish for supplementary shoes
Adidas has been developing its Futurecraft sneaker line for more than five years. Adidas initially collaborated with 3D software developer Materialise to use advanced 3D foot scanning technology to accurately measure runners’ feet. At the time, the company praised the “open source partnership” as a landmark project between creators and manufacturers.
Using the experience gained in cooperation with Materialise, Adidas has developed the “Ultraboost Parley” shoes in cooperation with the environmental organization Parley. The training shoes are made of 95% plastic waste, making it very environmentally friendly, but at that time, Adidas has begun to focus on the upcoming Futurecraft product line.
Carbon invented the first Futurecraft running shoe 4D and used its digital light synthesis (DLS)3D printingTechnology reduces production time from 90 minutes to only 20 minutes. Although the final midsole proved to be able to consider the wearer’s movement, stability and comfort needs, it has not yet been integrated into the complete footwear.
It wasn’t until January 2018 that the first fully formed 4D sneakers came out, but the price was as high as $20,000. The eBay seller in question competed with another listed company on Grailed, which advertised a more reasonable price of $3,000, but the shoes were still an expensive exclusive item.
Since then, Adidas has cooperated with fashion brand Stella McCartney to develop AlphaEdge 4D contour sports shoes, and cooperated with Japanese designer Yohji Yamamoto to develop fashionable Y-3 shoes. Now, Adidas showed off its latest Futurecraft innovation, took a more sporty approach, and returned to the idea of producing advanced additive running shoes.
Adidas’ latest Futurecraft shoes use innovative data-driven new technology to carry out3D printing. The picture comes from Adidas.
Adidas Futurecraft STRUNG footwear
Adidas collaborated with Carbon and Materialize in its Futurecraft project to design a running shoe that can provide every athlete with the best running experience. In order to achieve this goal, Adidas has developed a new proprietary “STRUNG” process that combines athlete data,3D printingFusion with robotics technology into a unique combination, weaving each thread to achieve the best performance.
The structure of STRUNG was developed using Materialize 3-matic data optimization software, which allows flexibility in the design of the midsole without affecting its rigidity or strength. Data mapping before production also allows Adidas designers to test different structures before manufacturing and create a single composite material with specific performance areas and properties.
The final proof-of-concept sneaker uses a lightweight lattice upper that can be accurately supported, bent and breathable, forming a “cocoon” for the runner’s foot. Using a data-driven approach also allows the deployment of materials to optimize specific areas of the shoe. For example, a stronger red line is used to provide grip on the heel, while its softer yellow line provides the user with greater flexibility in the forefoot.
“We like to talk about our products’services for athletes’. In this case, we will get more revenue, so they can focus on sports without them.”
The company’s latest running shoes are based on the Futurecraft Loop technology launched last year, which uses a fully reusable thermoplastic polyurethane (TPU) material and has no adhesive to hold the sneakers together. Therefore, additively manufactured footwear is hardly wasted, giving it a strong environmental certificate and performance advantages.
However, Adidas has not updated its latest3D printingRunning shoes are marketed as a sustainable option. In fact, STRUNG is designed to meet the needs of road runners. This lightweight prototype weighs only 220 grams (7.7 ounces). Adidas’ own motion capture test is based on a fast short sprint, showing the purpose of its STRUNG series of shoes.
Currently, STRUNG is just a prototype, but Adidas’ goal is to develop a series of new STRUNG trainers for different sports and runners in the future, and it is planned to be launched in early 2022.
