3D打印機咙鞍，很近又感覺很遠，到底它能干啥辟拷？
1质涛，3D打印機的工作原理
3D printing (also known as “additive manufacturing”) involves creating a 3D object from a digital file, building it up layer by layer. So, if you were to slice a finished 3D printed object open, you’d be able to see each of the thin layers, a bit like rings in a tree trunk.
簡單來說，首先創(chuàng)建對象箱蝠，其次逐層建構(gòu)
The main benefit of this approach is that even complex shapes can be created much more easily, and using less materials than traditional manufacturing methods (which is good for the environment and the bottom line). Transport needs are reduced, since parts and products can be printed on-site. And one-off items can be made quickly and easily, without worrying about economies of scale – which could be a game-changer for rapid prototyping, custom manufacturing, and creating highly personalized products. What’s more, the materials used for 3D printing can be pretty much anything: plastic, obviously, but also metal, powder, concrete, liquid, even chocolate.
好處和優(yōu)勢也是非常明顯的：
1续捂，化繁而簡，
2宦搬，材料最優(yōu)牙瓢，
3，運輸成本
4间校，高效
5矾克，原材料廣泛
4D在3D基礎(chǔ)上增加了自我修復(fù)功能，目前還是在實驗階段憔足。

8.盲人作品
9.你自己（縮影）
10.形狀記憶材料
上述有沒有覺得很興奮的應(yīng)用呢胁附？
當(dāng)然這些都是已經(jīng)比較成功的。
未來的應(yīng)用一定是更廣泛的滓彰。
