The footwear industry has been growing over the years. It is expected that the global market for footwear will reach $371.8 billion by 2020, mainly driven by new design trends and the expanding middle class population. The footwear includes athletic and non-athletic shoes used by individuals of all age groups and genders. The trends demonstrate that there is a demand for trendy yet comfortable footwear in the market.
Shoe manufacturers have been able to use material innovations combined with new technologies to create a wide variety of shoe designs and mass customization. Shoe design technology includes 3D printing of shoes for athletes and for the everyday user. Orthopedists, physiotherapists, chiropractors, and podiatrists who use 3D printing in manufacturing are able to acquire R&D Tax Credits towards their business.
Orthotic insoles for shoes can be expensive and time consuming to order but additive manufacturing has been able to change that by printing custom insoles for shoes. These insoles are less expensive and easy to make. Shapecrunch determined that by using additive manufacturing, they are able to custom make insoles for individuals who suffer from diabetes, flat feet and plantar fasciitis. The process consists of the doctor first scanning the patient’s foot and then entering the data into software that takes 3D scans and begins to print them. These 3D printed insoles will provide runners who are suffering with diabetes or other foot ailments with relief.
Brooks is a top brand in specialty running shoes, which has found ways to integrate additive manufacturing computer technology with the running industry. They use FitStation powered by HP which takes measurements of runners’ feet and analyzes their gait. Once the scans are conducted, the technology measures the pressure points along the foot as it lands each stride. The data collected helps determine how much polyurethane should be injected in the shoe’s insole to achieve the right density and comfort for the user. This advanced technology will help customize athletes’ shoes and make their shoes withstand the long run.
Prodways Group, a subsidiary of Groupe Gorgé, has developed insoles, midsoles and outsoles that are easily manufactured and customizable for customers. Prodways Group uses thermoplastic polyurethane (TPU) to print flexible soles for runners’ shoes. The midsoles are created to have a high resistance to fatigue at the same time being cost and time effective for end users. The printer that is used is the DLP MOVINGLight which is 3D printing technology that is patented by Prodways. This technology speeds up product launches, providing customized products for users in the shoe market.
Prodways集团，Groupe Gorgé的子公司,开发了容易制造并可定制的鞋垫、中底和大底。Prodways集团用热塑性聚氨酯(TPU)打印出灵活性非常高的鞋底，特别适合专业运动员。鞋底夹层具有较高的抗疲劳性能，同时成本和制作时间都具有很强的优势。使用的是DLP MOVING Light Prodways专利的3 d打印技术。这项技术升级的产品的推出,为用户提供了市场需求很大的定制化服务。
Manufacturers test fabrics and try to discover various ways to improve performance. When it comes to the competitive sports field a few seconds’ difference can be a game changing win or loss. Both New Balance and adidas have tried using 3D printing to improve traction and energy transfer for users’ shoes. Adidas designed shoes specifically for long distance track racing. The soles of the shoes were engineered to be stiff and thin to provide support for runners as they curved around the track. Runner David Rudisha completed an 800m race in just 1 min 42 seconds and walked away with gold for Kenya during the 2016 Olympic Games in Rio. 3D printed adidas shoes kept him stabilized and prevented him from slowing down on the curves. Shoe technology can clearly improve an athlete’s performance.
制造商通过测试各种面料希望发现有效的方法来提高性能。在竞技体育领域几秒的差别都是一个决定成败的因素。New Balance和adidas都尝试过使用3 d打印技术来提高鞋子的牵引力和能量转移。Adidas的鞋子适合长跑爱好者或运动员。鞋底的设偏硬和薄，为跑步者支持他们通过弯曲轨道。运动员David Rudisha的800米赛跑成绩为短短的1分钟42秒,夺走了2016里约奥运会的金牌。3D印刷阿迪达斯鞋保持了他的稳定性,减少了他的减速曲线。以上说明，制鞋技术明显能提高运动员的成绩。
In China, leading professional sports brand Peak used additive manufacturing to print its first pair of running shoes. The comfortable and breathable shoes are made of a lattice structure insole by using a 3D printer. They are lightweight and elastic, providing ease of range of motion and comfort for the wearer. Peak shoes have been worn by NBA player Dwight Howard and they design foot molds for other players as well. Howard raves about the improvements in his performance due to his 3D printed basketball boots:
在中国，领引职业体育品牌前行的Peak匹克，也利用增材制造技术打印了第一双跑鞋。使用3D打印机制造出了舒适、透气的晶格结构鞋垫。重量轻、弹性好，为跑步者提供了方便和舒适。NBA球员Dwight Howard穿了Peak的定制鞋,还给其他球员设计了最适合他们的鞋子。Dwight Howard还这样赞扬专门为他设计的3D印刷篮球鞋:
“This pair of boots has obviously higher performance than traditional ones. I felt that the 3D printed soles and vamp side walls enable a more comfortable wearing experience. Maybe, one day in the future, you’ll see me wearing the 3D printed basketball boots, footwear designed based on R&D carried out by PEAK, during an NBA competition.”
Additive manufacturing continually demonstrates the potential it has for changing the future footwear industry.
