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樹脂來打印，你只要把你的3D模型文件發給3D打印服務公司，就可以打印了，打印出模型后，還不是透明的，需要經過打磨，噴油，過UV才會有完全透明的手板模型。3D打印相比傳統方法，時間更快，也更低，特別是復雜的模型結構。

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.

在傳統手板行業，做透明手板主要有兩種材料——PC和亞克力，這兩種手板的制作方式基本是一樣的，主要是CNC加工和真空復模。

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話，基本上就只有三個步驟：編程、CNC加工和打磨，前兩個環節是相同的，只有在打磨這個環節是有所不同，亞克力只需要用砂紙或者拋光機打磨，就可以達到透明的效果，而PC手板則需要通過熏蒸才能達到透明的效果。

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.

而通真空復模的方式來做透明手板的原理基本上是這樣的：先通過CNC加工或SLA制作一個原型，然后再通過這個原型制作硅膠模具，再利用這個硅膠模具進行批量復制。不過通過這種方式做出來的手板只能是半透明的，而且在硬度以及耐高溫方面都比不上CNC加工出來的。

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.
