Generally speaking, rapid prototyping can be divided into two major processing technologies: light curing rapid prototyping system and laser selective sintering rapid prototyping. But what are the differences between the two processes? Today, we will briefly explain the different processing methods of rapid prototyping for your reference.
The principle of these two forming technologies are very similar. In addition, these two processes, which are indispensable for the manufacture of hand plate dies, are widely used in industrial design.
①Photosolidification Rapid Prototyping Process: The material used in this process is powder material. A liquid-shaped photosensitive resin is common. Its advantage is that all powdered substances that can be dissolved can be used to make prototypes or models. But the disadvantage is that the precision of the products processed is quite different.
②Laser selective sintering method: This process can sinter many materials, even some cold door ceramic layer. Therefore, the technology of laser selective sintering is more widely used, and has the characteristics of wide application range and strong attraction.
①Rapid prototyping of UV curing is suitable for some high-grade crafts, which requires high precision and high surface finish.
②Laser powder sintering is suitable for large-scale products with low roughness and relatively low price.
