Before this concept can become a reality, there are advancements that need to happen in 3d printing technology. For example, the materials currently available don't offer the durability or softness necessary for wearing every day or for athletic use. Further study is also required to ensure those materials are biocompatible and safe for consumers. Today, the cost and amount of time it takes to print a pair of shoes are both too high. But, the 3d printing industry is evolving quickly, and while material challenges may prohibit immediate implementation, user-driven rapid manufacturing will be realized in the near future.
