一旦3D打印设备价格下降,创业者将蜂拥而至,探寻如何利用它制造更多产品。一个球,一个茶杯,一个齿轮,甚至一辆电动汽车,尽管3D打印机无法印刷钞票,但却能制作出几乎所有物品的实体原型。3D打印运用了增材制造技术,其使用的技术脱胎于传统的纸张打印。然而,它并不是传统的二维输入打印模式,而是生成真实的实体原型物。目前3D打印 Once the price of 3D printing equipment drops, entrepreneurs will flock to explore how to use it to create more products. A ball, a teacup, a gear, and even an electric car, a solid prototype of almost any item, even though the 3D printer can not print a banknote. 3D printing uses additive manufacturing technology, which uses technology born out of traditional paper printing. However, it is not a traditional two-dimensional input printing mode, but it generates real physical prototypes. Currently 3D printing
