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??
1、 Similarities between the two rapid prototyping technologies
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.
2、 Differences between two rapid prototyping technologies
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.
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.
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.
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!
