Technical principle of selective laser sintering (SLS).
Selective laser sintering (SLS) is a powder sintering technology that uses a high-energy laser beam to melt powder materials and selectively sinter them together to create complex three-dimensional objects. SLS technology has the advantages of high precision, high strength, and high flexibility, and is widely used in the manufacture of complex parts, medical devices, automotive parts, and other fields.
The basic principles of SLS technology are:
A layer of powder material is first laid on a powder bed, and then the powder is scanned and sintered using a high-energy laser beam based on data information in a digital model file. In this process, the energy of the laser beam melts and sinters the powder material together to form layers of solid. After each layer of sintering is completed, the table is lowered a certain distance to allow a new powder layer to be laid on the powder bed and the next layer is sintered. This process is repeated until the entire three-dimensional object is manufactured.
Compared to other 3D printing technologies, SLS technology has some unique advantages. First of all, SLS technology can use a variety of powder materials, such as metals, plastics, ceramics, etc., so it is possible to manufacture a variety of objects with different properties and functions. Secondly, SLS technology has high manufacturing accuracy and surface quality, which can manufacture complex geometries and fine internal structures. In addition, SLS technology can also realize the parallel manufacturing of multiple parts, which greatly improves production efficiency.
