#3DStartup: Voxel8, revolutionising footwear & athletic apparel design and production
Voxel8 is a young American company that has developed a multi-material additive manufacturing solution focused mainly on the design of sports shoes and clothing. While many actors have focused on creating 3D printed soles, Voxel8 designs the entire upper part of the shoe. Its ActiveMix process allows the printing of high-performance and coloured reactive polyurethanes. The startup hopes that it will enable more players to offer mass-customised solutions locally, and at a lower cost.
Co-founder Travis Busbee explained how this platform works and the associated benefits. Travis Busbee background is Materials Science
and Engineering. He discovered additive manufacturing as a PhD student in Jennifer Lewis’ Lab at the Harvard School of Engineering and Applied Sciences. His first experiences with additive manufacturing started with developing brand new materials and writing programs to create fully 3D printed multi-material pharmaceutical testing devices with printed electronic sensors. He was co-first author of the Nature materials publication “Instrumented cardiac microphysiological devices via multimaterial three-dimensional printing”.
About ActiveMix ® system: ActiveMix® print heads are highly precise dynamic mixing and dispensing heads that enable additive manufacturing with reactive high performance elastomers like polyurethanes, silicones, and epoxies. They enable dynamic changes of the material properties of the parts that are printed, by changing the composition of the material as it is patterned. By varying the ratios of the same set of raw materials, you can achieve material characteristics that vary from something like a rubber band, to a rigid piece of plastic, and anywhere in between.
Voxel8’s ActiveImage® process takes things one step further by enabling full digital color control of the printed parts. With typical additive manufacturing technologies, you need to change the material feedstock if you want to change the properties of the printed parts, and each printed part is generally limited to a single material and a single color. With ActiveMix® and ActiveImage® Printing Technologies, you can print an extremely wide range of material properties in full digital color within a single printjob, without ever changing the base raw materials.
These groundbreaking new technologies have been integrated into a system that called ActiveLab® Digital Fabrication System (including hardware, software, and proprietary material formulations), that is now for sale for $250,000. Another important piece of their ecosystem is a software tool that have developed that enables product design with digitally defined zonal tuning of material properties. The full system was initially created for the design, prototyping, and production of unique new athletic footwear uppers and apparel with zonally tuned performance and full color. In the future, this system can be utilized in other emerging fields such as sporting goods, medical devices, wearables, and consumer products.
How does it impact the footwear industry?
Right now, it takes athletic footwear companies 12-18 months to bring new products to market (Design Sketch to Shelves). Each new product requires a tremendous amount of tooling to bring to market (think about 5-15 pieces of tooling per size, 21 different sizes, left shoe and a right shoe, more or less $1000 per piece of tooling). The prototyping and wear testing process frequently requires weeks or even months per iteration. The processes required to manufacture are extremely labor intensive, so they have to happen in Asia, even though labor prices in Asia continue to rise. This also means that shoes spend weeks on a boat traveling to many of the consumer hotbeds like the US and Europe.
Meanwhile, this is still the fashion industry, and the fashion industry is changing faster than ever before. It’s almost impossible to predict future fashion trends 12+ months in advance. Nonetheless, footwear companies must place orders for hundreds of thousands of pairs of a particular shoe line before they understand demand for a product. Young consumers expect new hot products to drop constantly. They are after something unique and customized, rather than wanting the same thing that everyone else has.
Long lead time, tooling and labor heavy manufacturing processes, will not be able to give the modern consumer what they want, and the footwear companies are fully aware. That’s why they are actively searching for a solution. A battle is waging behind the scenes to win the digital manufacturing revolution in athletic wear. Athleticwear brands are investing heavily in an attempt to modernize their supply chain before their biggest competitors. You can see examples of this in Adidas’ speedfactory, Nike’s partnership with Flex, Reebok’s Liquid Factory, Under Armour’s Lighthouse, and the list goes on. Voxel8 is The Digital Manufacturing Solution for athletic footwear uppers.
Benefits of your technology?
- Dramatically reduced time to market (from 1.5 years to weeks)
- Unique new designs to increase the appeal and performance of footwear products
- Ability to manufacture closer to large customer bases (i.e. US and Europe) due to reduced labor costs
- Individual customization of both mechanics and aesthetics
- Capability to introduce smaller batches of product to market and immediately respond to demand (Zero Tooling Cost & Agile Manufacturing Processes)
- And comparing it to other additive manufacturing technologies on the market, it has several points of differentiation, such as:
- Ability to print directly onto existing objects without the need for adhesives or assembly process– Ability to fabricate structures with high performance elastomers (that can withstand millions of bending/flexing cycles and elongations >600%) at costs that are significantly lower than typical 3D printing materials. This includes polyurethanes, medical grade silicones, and epoxies.
- Ability to embed high resolution full-color images inside of structural parts.
