High Power Blue Laser Module for SLS 3D Printing (SLS Sintering)

        Selective Laser Sintering (SLS) is a 3D printing technology that uses laser as a heat source to sinter powder materials layer by layer into three-dimensional objects. The application of blue laser in SLS technology is because blue light has a high energy density and good material absorption characteristics, which enables it to effectively heat the powder material to the melting point and achieve bonding between powder particles.

The role of blue laser in SLS technology can be summarized as follows:

1. High energy density: The energy density provided by blue laser is sufficient to quickly melt powder materials, thereby speeding up printing.

2. Precise control: Blue laser integrates field mirror and galvanometer. The laser beam can be moved and adjusted accurately according to the digital file of the 3D model through the galvanometer to achieve high-precision printing.

3. Material compatibility: Blue laser is suitable for a variety of polymer powders, including nylon, polycarbonate, etc., which increases the material selection range of SLS technology.

4. Economical: The use of semiconductor blue laser reduces costs, making SLS technology more economical and practical, making it possible for 3D printing (SLS sintering) to enter the consumer level.

5. High-speed printing: Blue laser can achieve high-speed printing and improve production efficiency.

6. Easy to adjust: Using existing laser accessories, such as field mirrors, the parallelism of the laser beam can be easily adjusted to meet different printing needs.

        However, SLS technology also has some challenges, such as post-processing work after printing, material shrinkage problems, surface roughness, etc., which need to be considered and solved in practical applications.

The mature application of blue lasers has not only promoted the development of SLS technology, but also brought more possibilities to the 3D printing industry, especially in the manufacture of complex structures and high-performance parts. With the continuous advancement of technology, we can expect that the application of SLS technology will be more extensive and efficient in the future.
