Many people may not know, many people may not know, the hand is the first board, after the design drawing comes out, 3D printing or CNC processing is needed to make a template to test the appearance and functional structure, so as to avoid mistakes.

　　为什么我们需要做纸板模型?由于产品开发或设计需要制作手板，所以制作手板模型是验证产品可行性的步。它是检测产品缺陷、缺陷和缺陷从而改进缺陷的更直接、更有效的方法。3D打印和数控手版是常用的手工制作模型。那么我们应该如何利用他们的优势呢?我们应该学会比较以下几点:

　　Why do we need to make cardboard model? Because product development or design needs to make handboards, making handboards model is the first step to verify the feasibility of products. It is the most direct and effective method to detect product defects, defects and defects so as to improve defects. 3D printing and numerical control hand plate are commonly used hand-made models. So how can we make use of their advantages? We should learn to compare the following points:

　　型号材质对比:

　　Model material comparison:

　　3D印制板:材料利用率高，不浪费，材料要求高。

　　3D PCB: high material utilization, no waste, high material requirements.

　　数控手板:材料利用率不高，浪费大，但能加工的材料种类很多。

　　CNC hand board: the utilization rate of materials is not high and the waste is large, but there are many kinds of materials that can be processed.

　　手板型号处理对比:

　　Comparison of handboard model treatment:

　　3D打印手版:可加工各种复杂表面及异形结构。

　　3D printing hand plate: it can process various complex surfaces and special-shaped structures.

　　数控手版:复杂零件需要多次加工，编程需要分离。

　　CNC hand plate: complex parts need to be processed many times, and programming needs to be separated.

　　手板型号成本对比:

　　Cost comparison of handboards:

　　3 d打印平板电脑:

　　3 D printing tablet:

　　配有驱动软件，生产速度快，无需培训。

　　Equipped with driver software, fast production speed, no need for professional training.

　　一次多件，无需人工加工。

　　More than one piece at a time, no need for manual processing.

　　精度低，无加工误差;

　　Low precision, no machining error;

　　数控加工handplate:

　　CNC handplate:

　　的程序员和的健美操。

　　Professional programmer and professional aerobics.

　　一次只能加工一个零件，人工成本高。

　　Only one part can be processed at a time, with high labor cost.

　　机械故障或夹紧不良。

　　Mechanical failure or poor clamping.

　　3D打印和CNC手的样品通常需要少量的试产，发现批次不足以改善。产品设计不可能，甚不能使用，一旦缺陷完全被抛弃，直接生产，极大地浪费了人力物力和时间。3D打印和数控加工板主要用于制造家用电器和数码产品。CTS、儿童玩具、汽车零部件等工业制造领域。

　　3D printing and CNC hand samples usually need a small amount of trial production, and it is found that the batch is not enough to improve. Product design can not be perfect, or even can not be used. Once defects are completely abandoned, direct production, a great waste of human and material resources and time. 3D printing and NC processing board are mainly used to manufacture household appliances and digital products. CTS, children's toys, auto parts and other industrial manufacturing fields.
