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(shù)的相同點(diǎn)

1、 Similarities between the two rapid prototyping technologies

這兩種成型技術(shù)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(shù)，在工業(yè)設(shè)計(jì)上也是應(yīng)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(shù)的不同點(diǎn)

2、 Differences between two rapid prototyping technologies

光固化快速成型系統(tǒng)所用的材質(zhì)是粉末狀的物質(zhì)激光選區(qū)燒結(jié)快速成型系統(tǒng)所采用的一種液態(tài)形狀的光敏樹(shù)脂，光固化快速成型系統(tǒng)優(yōu)點(diǎn)在于，凡是可以溶解的所有粉末狀的物質(zhì)，都是可以用來(lái)制造原型或者模型的，所制造出來(lái)的產(chǎn)品都是可以用作產(chǎn)品的首樣測(cè)試和結(jié)構(gòu)組裝件的。所以激光選區(qū)燒結(jié)法可以利用的材質(zhì)非常廣泛，比如說(shuō)尼龍材質(zhì)，比如說(shuō)PC材質(zhì)，比如說(shuō)其他的臘粉，甚有些五金的材質(zhì)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(guò)以上方式加工出來(lái)的產(chǎn)品，精度都是相差比較大，但是因?yàn)榧す膺x區(qū)燒結(jié)法可以燒結(jié)很多的材質(zhì)，甚有些冷門(mén)的陶瓷層都能做到，所以說(shuō)激光選區(qū)燒結(jié)法工藝更加具有廣泛的應(yīng)用性，在行業(yè)的應(yīng)用范圍大，吸引力強(qiáng)，這些特點(diǎn)也能掩蓋一下他精度不高的缺點(diǎn)，和表面粗糙，已經(jīng)效率低下的問(wèn)題。因?yàn)閺V大客戶(hù)了解了這些屬性之后，就可以將自己的產(chǎn)品在選擇工藝的時(shí)候有個(gè)參考依據(jù)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(chǎn)品，適合用光固化成型快速成型，如果是一般的大型的產(chǎn)品，粗糙程度要求不高，相對(duì)低廉的產(chǎn)品，就選擇光固化成型激光粉末燒結(jié)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(shí)際應(yīng)用中結(jié)合上述兩種快速成型技術(shù)的優(yōu)缺點(diǎn)，為自己的產(chǎn)品增加成功的幾率，以及降低公司的預(yù)算成本。這在行業(yè)競(jìng)爭(zhēng)激烈的當(dāng)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!
