The handboard model itself is not mass-produced. Generally, only a few or dozens of products can be produced at a time. If we want to reproduce, we need to open the mold. The handboard model is mainly to inspect the external performance of the product, so that the manufacturer can understand the feasibility of the product and avoid the huge cost of directly opening the mold. So the handboard model is not many, Here are some plans for making handboards:

CNC手板模型制作

CNC handboard model making

CNC手板模型综合计算机辅助设计（CAD）、计算机辅助制造(CAM)、计算机数字控制（CNC）等技术，把计算机上构成的三维模型由整块材料在CNC数控加工上雕铣而成，再配合精湛的手工处理，因此近代工业称之为CNC手板模型。

CNC handboard model integrates advanced technologies such as CAD, cam and CNC. The three-dimensional model made up of computer is carved and milled by a whole piece of material in CNC machining center, and then matched with exquisite manual processing. Therefore, modern industry is called CNC handboard model.

快速成型

Rapid prototyping

SLA（StereolithogrphyApparatus）工艺也称光造型或激光固化快速成型，由CharlesHul于1984年获美国。1988年美国3DSystem公司推出商品化样机SLA-I，这是世界上台快速成型机。SLA各型成型机机占据着RP设备市场的较大份额。

SLA (stereolithography apparatus) process, also known as light modeling or laser curing rapid prototyping, was patented by Charles hul in 1984 in the United States. In 1988, 3dsystem company of the United States launched SLA-I, the first rapid prototyping machine in the world. SLA molding machines occupy a large share of RP equipment market.

真空注型（硅胶复模、翻模）

Vacuum injection (silica gel mold, turn over mold)

真空注型，又称真空复模，即在真空条件下利用原型直接复制出产品。设计完善后的产品可通过各种加工方法如CNC、SLA等先得到原型，再通过原型复制得到产品。复制出来的产品精度高、强度好，为一完整整体，完全满足设计需求的各种功能。适用于小批量的功能型零件的试制，减少直接开钢模的成本和风险。

Vacuum injection molding, also known as vacuum re molding, is to use the prototype to directly copy the product under vacuum conditions. After the design is completed, the product can get the prototype first through various processing methods such as CNC, SLA, and then get the product through the prototype replication. The copied products have high precision and high strength, and are a complete whole, which fully meet the design requirements of various functions. It is suitable for trial production of small batch of functional parts and reduces the cost and risk of directly opening the steel mould.
