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，不會受到形狀的限制，可以打印任何形狀復雜的手板，越復雜可以體現出3D打印技術的優越性，無論多么復雜的手板，都可以打印出來，它的優點是減少生產成本和時間成本。這種加工方式是按重量收費的，如果體積大的手板用3D打印方式來做就不劃算。
                

　　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：所加工的材質非常廣泛，除了軟膠類，其它塑膠和金屬的材料都可以加工，而且加工出來的精度高，可以達到正負0.02-0.10mm；他的特點是速度快，強度高，可加工大尺寸手板，CNC加工的形狀會受到限制，如果太復雜的手板，則需要拆件來做了。

　　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.

　　真空復模：用于小批量生產，需要先做原版，再去做一個硅膠模具，硅膠復模制作周期短，便宜，容易占領市場，適用于小批量手板制作，一個硅膠模具可以做出10-15件左右；再使用就容易產生變形，縮水等情況，在真空條件下，對澆注料進行脫泡、攪拌、預熱、注型，并在恒溫箱中進行二次固化成型，硅膠復模的手板模型可以達到ABS等材質的強度和硬度。

　　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.
