The 3D-printed Running Shoes

Though 3D-printed technology has been available for about twenty years, it has not been accepted by most people because of the high cost and the slow printing speed. But that may change soon, thanks to German sportswear manufacturer Adidas. The company revealed Adidas 3D Runners, featuring a 3D-printed sole that provides athletes with the extra cushioning needed for their excellent performance. Unlike traditional soles, these are not foam, but web-like structures which take into account the impact areas of feet. This means that the structures are thicker in the shoe’s front and back, both of which hit the ground hard when the athlete runs. Not surprisingly, the 3D-printed running shoes that were only available for sale in New York City, London and Tokyo were an instant hit and sold out within hours of their release. Though not available to the mass market, the shoes are an encouraging step in the right direction for more widespread use of the 3D-printed technology. Adidas is working on making additional 3D- printed clothes, and as the technology develops and the printing speed increases, the prices will start to go down. Being able to offer 3D-printed shoes at a low cost has the potential to change the shoe industry as we know it today. That is because instead of having to choose from ready-made sizes, customers will be able to make shoes for themselves. The process would also be cost-effective for manufacturers. While printing 3D objects may sound complicated, the process is relatively easy. Once the design is downloaded to a printer, a laser creates layers of materials, usually plastic or metal. These layers are put above one another and mixed together until the product is complete.
