Product prototype is often used in product design companies. If some products are required to be transparent, they can be processed with transparent materials. Now, those who make transparent hand boards can use 3D printing and traditional CNC processing and manufacturing. Here is a brief introduction.

3D打印透明手板可以使用透明树脂来打印，你只要把你的3D模型文件发给3D打印服务公司，就可以打印了，打印出模型后，还不是透明的，需要经过打磨，喷油，过UV才会有完全透明的手板模型。3D打印相比传统方法，时间更快，也更低，特别是复杂的模型结构。

3D printing transparent hand board can be printed with transparent resin. You only need to send your 3D model file to the 3D printing service company to print it. After printing out the model, it is not transparent. You need to polish, spray oil and UV to have a completely transparent hand board model. Compared with traditional methods, 3D printing is faster and cheaper, especially for complex model structure.

在传统手板行业，做透明手板主要有两种材料——PC和亚克力，这两种手板的制作方式基本是一样的，主要是CNC加工和真空复模。

In the traditional handicraft industry, there are two main materials for making transparent handicraft: PC and acrylic. The manufacturing methods of these two kinds of handicraft are basically the same, mainly CNC processing and vacuum replica.
         

采用CNC加工的方式做透明手板的话，基本上就只有三个步骤：编程、CNC加工和打磨，前两个环节是相同的，只有在打磨这个环节是有所不同，亚克力只需要用砂纸或者抛光机打磨，就可以达到透明的效果，而PC手板则需要通过熏蒸才能达到透明的效果。

There are basically only three steps to make a transparent hand board by CNC processing: programming, CNC processing and polishing. The first two steps are the same. Only in the polishing process is different. Acrylic only needs sandpaper or polishing machine to achieve the transparent effect, while PC hand board needs fumigation to achieve the transparent effect.

而通真空复模的方式来做透明手板的原理基本上是这样的：先通过CNC加工或SLA制作一个原型，然后再通过这个原型制作硅胶模具，再利用这个硅胶模具进行批量复制。不过通过这种方式做出来的手板只能是半透明的，而且在硬度以及耐高温方面都比不上CNC加工出来的。

The principle of making transparent hand board by vacuum replica is basically like this: first, a prototype is made by CNC processing or SLA, and then the silicone mold is made by this prototype, and then the silicone mold is used for batch replication. However, the handboard made in this way can only be translucent, and its hardness and high temperature resistance are not as good as those processed by CNC.
