KAV Sports Enables Mass Customization with Custom Engineered Materials

Every bike helmet on the market is made from injection-molded expanded polystyrene (EPS) foam, which has serious limitations. Bike helmets created with EPS foam are manufactured in one to three sizes limiting the fit of the helmet. To address this they add retention devices that add complexity, weight and a potential failure point. EPS foam is a great insulator, but in the context of cycling, that means it traps heat, increasing perspiration and reducing comfort. 

KAV's cutting-edge software enables mass customization. Their technology begins by analyzing specific anatomical points on the head and then creating a precise 3D model of each individual's head. This data is then seamlessly converted into a set of manufacturing instructions for their 3D printers, enabling KAV to create truly customized helmets tailored to any head type in just a matter of hours. The software platform is beaming with potential for other customization application as well. 

Prior to working with Jabil, KAV evaluated more than 20 materials, which were all compromised in energy attenuation — the ability to absorb impacts — or lacked stability across environmental conditions. 

KAV had several specifications for their custom material. First, it had to be at least as light as EPS and maintain stability in temperatures ranging from -15 degrees Celsius to over 60 degrees Celsius. Additionally, the new material had to demonstrate high impact and energy absorption across a matrix of impact tests spanning the spectrum of environmental conditions, impact speeds, impact locations and impacting objects. Layer adhesion, a characteristic missing from materials currently on the market, was also an extremely important factor to providing consistent performance regardless of the impacting vectors. 

Finally, exceptional surface finish was paramount. In order to achieve their mission of safety, KAV helmets not only had to improve protection but look like a premium product. Consumers have expectations with regard to fit and finish and the material had to have a comparable finish with the best helmets on the market.  

Not only is Jabil a great cultural fit for KAV because they understood KAV's mission and the consumers' need for a more protective helmet. Jabil provided multiple solutions in different form factors like powders, filaments and pellets, which made their innovative approach to material development unlike any other manufacturing solutions provider.  

Executed under one roof, Jabil's polymer science approach coupled with its material development process — which includes three crucial steps: formulation, compounding and system integration — combined to create the best material that fit KAV's requirements. 

• Formulation is the process of creating a specific material composition, whether that's polymers, pigments or fillers. This process results in a material's strength, flexibility and color. A proper formulation ensures that the additive material will have the necessary properties to perform well in the intended application. 
• Compounding is the mixing and blending of the formulated materials to create one complete mixture. This step is critical for achieving consistent and uniform properties throughout the additive material.  
• System integration incorporates the formulated and compounded materials into the additive manufacturing process. It's at this stage that we see how well a material performs.

By creating a custom material, KAV eliminated the need for expensive and time-consuming modifications to off-the-shelf materials. Instead, they got a material they trust and that works for their intended use.  

"Many people in additive manufacturing don't take our approach. They tend to take materials, throw them at the wall and see what sticks. And that's not a scientific or an engineered solution to customer problems," said Matt Torosian, director of product management at Jabil. 

With Jabil's help, KAV is the only custom helmet business that not only meets but exceeds the rigorous safety standards set by the U.S. Consumer Product Safety Commission. Their exclusive custom material sets them apart and gives them an unrivaled competitive edge. 

Existing suppliers in the marketplace could not operate at the pace KAV needed to penetrate the market. KAV is accustomed to feedback one day and fabricating a new helmet the next for testing and wanted a partner who enabled rather than constrained their iterative engineering process. Jabil's Quality Management System (QMS) is the backbone of our success and the success of our customers. A QMS guaranteed a consistent and high-quality final material iteration for KAV, with minimal defects and variations. It also ensures compliance with industry standards and regulatory requirements, giving them peace of mind that their product is ready to go to market. 

"It probably took us about nine months to develop the material for KAV, which I feel is pretty astounding considering how much innovation we needed to do and the fact that there was no other material on the market even remotely close to the performance that that we ended up developing," said Levi Loesch, Jabil process engineer. 

KAV's top priorities were to create an additive material that could protect bikers' heads, print according to the customer's head measurements and look amazing. By building to production rather than building to inventory, Jabil was able to help KAV respond to the customization needs of its consumers. 
"Our customers were mind blown that they could have something made for them at approximately the same price as other high-end helmets. They absolutely love it. They're blown away by the comfort," said Kwok. 

KAV offers custom-made helmets in three different colors: grey, black, and white, giving customers flexible choices. The helmets are made-to-order through a simple custom-fitting process, using 3D printing technology, and are delivered within two-to-three weeks.

Swift production through additive manufacturing not only expedites the delivery of goods to consumers but also boasts a host of additional advantages. Faster production can help reduce the amount of waste sent to landfills — a goal Jabil and KAV both seek to obtain — by producing goods that are more durable and have a longer lifespan, which means they will need to be replaced less often. KAV’s five-year warranty reflects the confidence in the fundamental durability of the new material and manufacturing process. 

Having a manufacturing partner that aligns with KAV’s mission and has robust manufacturing processes can help to increase profitability to support future R&D, maintain a strong reputation and attract consumers who want something quantitively better, all of which are vital for long-term success. 

"Jabil's material science expertise and innovation and their desire to push the boundaries of what's possible, in our case, to fulfill our mission of saving lives and reducing brain injuries, is vitally important to us when maintaining a strong partnership," Kwok said.

Having immediate access to each other has allowed for KAV and Jabil to be more innovative and collaborative. As a result of their partnership, Jabil produced a high-quality material that will aid in KAV’s efforts to increase bike safety.
