3D打印运动鞋

Adidas just debuted its newest shoe -- which has a 3D-printed sole. 3D printed materials are often rigid or malleable and wouldn't work well for a shoe. But with new technology, the material is springy and able to bounce back almost instantaneously. The technology works by using UV lasers to project a pattern for a midsole liquid. The light turns the liquid into a solid and the result is a flexible, but durable, midsole.
阿迪达斯日前亮出了它的最新款运动鞋，这款鞋的鞋底是3D打印出来的。3D打印出来的材料通常不易弯曲，或者是容易变形，所以该技术不适用于造鞋。不过有了新技术，打印出来的材料更有弹性，弯折后能够迅速恢复原状。制作鞋底夹层的液体倒入后，该技术会用紫外激光给鞋底塑形。激光会凝固液体，使其形成有弹力而且耐久的鞋底。
