目前市面上手板打樣大致分為3D打印手板,CNC手板,復模，逆向抄數等幾大類。但常用的還是3D打印手板與CNC手板加工了。在普及3D打印手板與CNC手板加工區別之前先來做個簡單的介紹。

At present, the prototype on the market can be roughly divided into several categories: 3D printing prototype, CNC prototype, replica, reverse copying, and so on. But the commonly used ones are still 3D printing hand boards and CNC hand boards for processing. Before popularizing the differences between 3D printing hand boards and CNC hand board processing, let's give a brief introduction.

什么是北京手板打樣，朋友們也許不知道，手板就是首板，簡單來講就是將圖紙(3D立體模型圖,看好哦，是3D立體圖，非2D平面圖)設計好了之后需要通過3D打印或者CNC加工先做一個樣品出來檢測一下外觀以及功能結構，裝配是否吻合，功能是否達標，參數是否符合要求等，從而達到避免直接開模不好修改以及節約成本之用。

What is the Beijing prototype prototype? Friends may not know, but the prototype is the first prototype. Simply put, after designing the drawings (3D three-dimensional model diagram, watch it, it is a 3D three-dimensional diagram, not a 2D plane diagram), a sample needs to be made through 3D printing or CNC processing to check the appearance and functional structure, whether the assembly matches, whether the function meets the standards, and whether the parameters meet the requirements, Thus achieving the purpose of avoiding direct mold opening and difficult modification, as well as saving costs.

我們為什么需要做手板模型？因為產品研發或設計需要做手板，做手板模型是驗證產品可行性的步，是檢測產品的缺陷、不足、弊端直接且有效的方式，從而對缺陷進行改善。3D打印手板和CNC手板是手板模型制作常見的手段，那么我們該怎么利用他們的優點呢？

Why do we need to make a prototype? Because product development or design requires a prototype, creating a prototype is the first step in verifying the feasibility of the product. It is a direct and effective way to detect defects, deficiencies, and drawbacks in the product, thereby improving the defects. 3D printing and CNC hand boards are common methods for making hand board models, so how can we utilize their advantages?

1、 材料利用率對比

1. Comparison of material utilization rates

3D打印手板：高的材料利用率，無浪費，對材料有要求；

3D printing board: high material utilization rate, no waste, and material requirements;

CNC手板：材料利用率不高，浪費，但是可以加工的材料有很多種；

CNC hand board: The material utilization rate is not high and waste, but there are many types of materials that can be processed;

2、加工對比

2. Processing comparison

3D打印手板：可加工各種復雜曲面及異形結構，一次性加工完成；

3D printing board: capable of processing various complex surfaces and irregular structures, completed in one go;

CNC手板：復雜零件需加工多次，需拆分編程工作量大，后期手工也比較復雜；

CNC hand board: Complex parts need to be processed multiple times, requiring a large amount of disassembly programming workload, and later manual work is also relatively complex;

3、成本對比

3. Cost comparison

3D打印手板：

3D printing board:

（1）自帶驅動軟件，快速制作，無需培訓；

(1) Equipped with driver software, fast production, no need for professional training;

（2）一次性可加工多個零件，無需人工值守 ；

(2) Multiple parts can be processed at once, without the need for manual attendance;

（3）精度不是很高，無加工出錯；

(3) The accuracy is not very high, and there are no machining errors;

CNC手板：

CNC hand board:

（1）需編程人員，操機；

(1) Professional programming personnel and machine operation are required;

（2）一次性只能加工一個零件，人工成本高；

(2) Only one part can be processed at a time, resulting in high labor costs;

（3）會存在操機失誤或裝夾不良。

(3) There may be machine operation errors or poor clamping.

以上就是3D打印手板與CNC手板加工之間的區別，了解兩者之間的差異之后，對自己的手板想要選哪種加工技術也是非常有幫助的。有項目需求都可以聯系我們http://m.tescen.com喲！
