目前市面上手板打样大致分为3D打印手板,CNC手板,复模，逆向抄数等几大类。但常用的还是3D打印手板与CNC手板加工了。在普及3D打印手板与CNC手板加工区别之前先来做个简单的介绍。

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.

什么是北京手板打样，朋友们也许不知道，手板就是首板，简单来讲就是将图纸(3D立体模型图,看好哦，是3D立体图，非2D平面图)设计好了之后需要通过3D打印或者CNC加工先做一个样品出来检测一下外观以及功能结构，装配是否吻合，功能是否达标，参数是否符合要求等，从而达到避免直接开模不好修改以及节约成本之用。

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.

我们为什么需要做手板模型？因为产品研发或设计需要做手板，做手板模型是验证产品可行性的步，是检测产品的缺陷、不足、弊端直接且有效的方式，从而对缺陷进行改善。3D打印手板和CNC手板是手板模型制作常见的手段，那么我们该怎么利用他们的优点呢？

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、 材料利用率对比

1. Comparison of material utilization rates

3D打印手板：高的材料利用率，无浪费，对材料有要求；

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

CNC手板：材料利用率不高，浪费，但是可以加工的材料有很多种；

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

2、加工对比

2. Processing comparison

3D打印手板：可加工各种复杂曲面及异形结构，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：复杂零件需加工多次，需拆分编程工作量大，后期手工也比较复杂；

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、成本对比

3. Cost comparison

3D打印手板：

3D printing board:

（1）自带驱动软件，快速制作，无需培训；

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

（2）一次性可加工多个零件，无需人工值守 ；

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

（3）精度不是很高，无加工出错；

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

CNC手板：

CNC hand board:

（1）需编程人员，操机；

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

（2）一次性只能加工一个零件，人工成本高；

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

（3）会存在操机失误或装夹不良。

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

以上就是3D打印手板与CNC手板加工之间的区别，了解两者之间的差异之后，对自己的手板想要选哪种加工技术也是非常有帮助的。有项目需求都可以联系我们http://m.axcwv.cn哟！
