An undergraduate at New Jersey Institute of Technology made his own plastic braces using a 三维 printer, US$60 of materials, and they actually worked.新泽西理工高校的一名本科毕业生用一台三维打印机及其60美元的原材料给自己制作了塑料牙箍，并且这种牙箍显而易见合理地。Amos Dudley had braces in middle school, but he didnt wear a retainer like he was supposed to, so his teeth slowly shifted back. He didnt want to shell out thousands of dollars for a whole new round of braces, so the digital-design major decided to make his own.阿莫斯·达德利初中的情况下就戴着到了牙筒，但他没按回绝戴着固位体，因此 他的牙逐渐移。他想花上上千美金去做一套新牙筒，因此 这名主学智能化设计方案的在校大学生就规定自身保证牙筒。The process wasnt exactly easy. He had to research orthodontic procedures and plot the route of his successive braces, so his teeth would move in the right way.制作牙筒的全过程并不比较简单。
他必不可少科学研究牙齿矫正的流程，绘图好相继更换的牙筒的制作方式，那样他的牙才不容易以有效的方法宽回家。But once that was done, all it took was fabricating a series of models out of relatively inexpensive plastic, and then following through on wearing them.但是一旦顺利完成之上流程，务必保证的便是用较为便宜的塑料制作一系列实体模型，随后就可以戴着到了。
And it was worth it for Dudley, whose smile turned out looking remarkable.对达德利来讲，这很有一点，他的微笑也看起来十分明显。Here is the process he went through:下列是他制作牙筒的全过程：First he took a mold of his teeth with alginate powder. These molds are very precise, and capture an amazing amount of detail, he writes.最先它用海藻酸盐粉末状制作了一个牙模貝。“这种模貝很仪器设备，猎捕了很多的关键点，”他提到。
I put the mold upside down in a yogurt container, and then filled it with liquid Permastone, he writes.“我将模貝推翻放置丰酸牛奶的器皿中，随后用液体的模仿大理石漆添充器皿，”他提到。When it came out, I simply broke off the top to reveal the casting, and used a razor blade to smooth out the surrounding area.“做成以后，我只是砸碎顶端，遮挡住铸模，殊不知用一把剃须刀片把四周风轻轻吹追。”Now he had a better sense of what was going on with his teeth.现如今他对他的牙齿矫正全过程拥有更优的了解。The picture below shows the steps, all 三维-printed out. Labeling the pieces is critical, he advises. They look virtually identical.下边这张相片展览了“牙齿矫正的流程”，全部的全是三维打印机出去的。
