Laser technology, as one of the most important technologies in additive manufacturing, has an important position in additive manufacturing.
I. Application of laser technology in additive manufacturing:
1. Metal powder sintering: laser technology can sinter metal powder into a continuous entity, which will eventually form the desired product. This method can be used to manufacture a variety of different products, such as aerospace parts, automotive parts, medical devices and so on.
2, plastic 3D printing: laser technology can also be used for plastic 3D printing, by heating and fusion of plastic powder, and finally make the required products. This method can be used to make a variety of different products, such as household appliances, toys, models and so on.
3, laser melting: laser melting technology is a manufacturing method in which metal or plastic materials are heated and melted by a laser, and accurately stacked in a specific location. This method can be used to manufacture a variety of different products, such as aerospace parts, automotive parts, medical devices and so on.
II. Advantages and disadvantages of laser technology in additive manufacturing:
1. Advantages: laser technology can provide very high precision and resolution, and can manufacture products with complex shapes. Laser technology can realize rapid production, can greatly reduce the production cycle and production costs. Laser technology can reduce material waste and can increase the material utilization rate to more than 90%. Laser technology is applicable to a variety of different materials, including metals, plastics, ceramics and so on.
2. Disadvantages : The price of laser equipment is high and requires a large investment. The manufacturing speed of laser technology is slow and cannot meet the needs of mass production. The surface quality of products manufactured by laser technology is not as good as products manufactured by traditional production methods.
