The purpose of making hand board is to verify whether the product design is reasonable and whether it meets the use requirements of the product, and can detect the structure, appearance and function of the product. Before making the hand board, it is necessary to prepare the 3D drawing of the design of the prototype. The 3D drawing is generally in the format of IGS, STP, step, PRT and XTL. It is based on the design of the drawing to process the hand board. According to the template, there are several common Processing method:

　　3D打印：就是激光快速成型SLA/SLS，不会受到形状的限制，可以打印任何形状复杂的手板，越复杂可以体现出3D打印技术的优越性，无论多么复杂的手板，都可以打印出来，它的优点是减少生产成本和时间成本。这种加工方式是按重量收费的，如果体积大的手板用3D打印方式来做就不划算。
                

　　3D printing: Laser Rapid Prototyping SLA / SLS is not limited by the shape. It can print any complex shape hand board. The more complex it is, the more it can show the advantages of 3D printing technology. No matter how complex the template is, it can be printed. Its advantage is to reduce the production cost and time cost. This kind of processing method is charged by weight. It is not cost-effective if 3D printing is used for large-scale handpieces.

　　cnc加工：所加工的材质非常广泛，除了软胶类，其它塑胶和金属的材料都可以加工，而且加工出来的精度高，可以达到正负0.02-0.10mm；他的特点是速度快，强度高，可加工大尺寸手板，CNC加工的形状会受到限制，如果太复杂的手板，则需要拆件来做了。

　　CNC processing: the processed materials are very wide, except for soft rubber, other plastic and metal materials can be processed, and the processing precision is high, which can reach 0.02-0.10 mm; its characteristics are high speed, high strength, and can process large-scale hand board, and the shape of CNC processing will be limited. If the hand board is too complex, it needs to be disassembled.

　　真空复模：用于小批量生产，需要先做原版，再去做一个硅胶模具，硅胶复模制作周期短，便宜，容易占领市场，适用于小批量手板制作，一个硅胶模具可以做出10-15件左右；再使用就容易产生变形，缩水等情况，在真空条件下，对浇注料进行脱泡、搅拌、预热、注型，并在恒温箱中进行二次固化成型，硅胶复模的手板模型可以达到ABS等材质的强度和硬度。

　　Vacuum re mold: for small batch production, the original version should be made first, and then a silica gel mold should be made. The production cycle of silica gel mold is short, the price is cheap, and it is easy to occupy the market. It is suitable for small batch production. A silica gel mold can make about 10-15 pieces. If it is used again, it is easy to deform and shrink. Under vacuum condition, the castable can be defoaming, stirred and pre processed The hand model of silica gel compound mold can reach the strength and hardness of ABS and other materials.
