Light curing rapid prototyping system and laser selective sintering rapid prototyping system are two main processing methods in the application of hand model making. So what are the similarities and differences between the two rapid prototyping??

一、兩種快速成型技術的相同點

1、 Similarities between the two rapid prototyping technologies

這兩種成型技術的原理都是非常相似的，另外都是作為手板模具制作用不可缺少的技術，在工業(yè)設計上也是應用的方法。

The principles of these two forming technologies are very similar. In addition, they are indispensable technologies for hand mold making, and they are also applied in industrial design.

二、兩種快速成型技術的不同點

2、 Differences between two rapid prototyping technologies

光固化快速成型系統所用的材質是粉末狀的物質激光選區(qū)燒結快速成型系統所采用的一種液態(tài)形狀的光敏樹脂，光固化快速成型系統優(yōu)點在于，凡是可以溶解的所有粉末狀的物質，都是可以用來制造原型或者模型的，所制造出來的產品都是可以用作產品的首樣測試和結構組裝件的。所以激光選區(qū)燒結法可以利用的材質非常廣泛，比如說尼龍材質，比如說PC材質，比如說其他的臘粉，甚有些五金的材質都是可以做到的。

The material used in the light curing rapid prototyping system is powdery material, a liquid photosensitive resin used in the laser selective sintering rapid prototyping system. The advantage of the light curing rapid prototyping system is that all powdery substances that can be dissolved can be used to manufacture prototypes or models, The manufactured products can be used as the first sample test and structural assembly of products. Therefore, laser selective sintering can use a wide range of materials, such as nylon, PC, other wax powder, and even some hardware materials.

通過以上方式加工出來的產品，精度都是相差比較大，但是因為激光選區(qū)燒結法可以燒結很多的材質，甚有些冷門的陶瓷層都能做到，所以說激光選區(qū)燒結法工藝更加具有廣泛的應用性，在行業(yè)的應用范圍大，吸引力強，這些特點也能掩蓋一下他精度不高的缺點，和表面粗糙，已經效率低下的問題。因為廣大客戶了解了這些屬性之后，就可以將自己的產品在選擇工藝的時候有個參考依據了。

The precision of the products processed by the above methods varies greatly, but because the laser selective sintering method can sinter a lot of materials, and even some unpopular ceramic layers, the laser selective sintering process is more widely applied, has a wide range of applications in the industry and strong attraction. These characteristics can also cover up its shortcomings of low precision, And rough surface, which has been inefficient. Because after knowing these attributes, customers can have a reference basis for their products when selecting the process.

一般是高檔的工藝品，精度要求高，表面光潔度要求高的產品，適合用光固化成型快速成型，如果是一般的大型的產品，粗糙程度要求不高，相對低廉的產品，就選擇光固化成型激光粉末燒結成型了。

Generally, it is a high-grade handicraft product with high precision and high surface finish requirements, which is suitable for rapid prototyping with light curing molding. If it is a general large product with low roughness requirements and relatively low price, it will choose light curing molding and laser powder sintering molding.

在工業(yè)的實際應用中結合上述兩種快速成型技術的優(yōu)缺點，為自己的產品增加成功的幾率，以及降低公司的預算成本。這在行業(yè)競爭激烈的當下顯得非常重要！

In the practical application of industry, combined with the advantages and disadvantages of the above two rapid prototyping technologies, it can increase the probability of success for its own products and reduce the budget cost of the company. This is very important in the current fierce competition in the industry!
