Light curing rapid prototyping system and laser selective sintering rapid prototyping system are the main two processing methods in the application of prototype model making. So what are the similarities and differences between these two types of rapid prototyping? ? 1. The similarities between the two rapid prototyping technologies The principles of these two molding technologies are very similar. In addition, they are both indispensable technologies for the production of prototype molds, and are also the most used methods in industrial design. Two, the difference between the two rapid prototyping technologies The material used in the light-curing rapid prototyping system is a powdery material. A liquid-shaped photosensitive resin used in the laser selective sintering rapid prototyping system. The advantage of the light-curing rapid prototyping system is that all powdery materials that can be dissolved are all Can be used to manufacture prototypes or models, and the manufactured products can be used as the first sample test and structural assembly of the product. Therefore, the laser selective sintering method can use a wide range of materials, such as nylon materials, such as PC materials, such as other wax powder, and even some hardware materials. The products processed by the above methods have a relatively large difference in accuracy, but because the laser selective sintering method can sinter a lot of materials, even some unpopular ceramic layers can do it, so the laser selective sintering method has more extensive applications. It has a wide range of applications in the industry and has a strong appeal. These characteristics can also cover up the shortcomings of its low precision, and the rough surface, which has been inefficient. Because after the majority of customers understand these attributes, they can have a reference basis for their products when choosing a process. Generally high-end crafts, products with high precision requirements and high surface finish requirements, are suitable for rapid prototyping with light curing. If it is a general large product, the roughness is not required, and the price is relatively low, light curing is the choice. Laser powder sintering is formed.Combining the advantages and disadvantages of the above two rapid prototyping technologies in practical industrial applications can increase the probability of success for their products and reduce the company's budget costs. This is very important in the current fierce competition in the industry!
