Selective laser melting of metals (SLM)-This is a 3D printing technology in which metal powder is used for direct printing of metal parts. When printing, the scraper applies a layer of metal powder to the supporting plate of the forming cylinder, and the laser beam selectively melts the powder in accordance with the transverse section of each layer of the part for processing the current layer. After the sintering of one layer is completed, the lifting system reduces the height of one layer of cross section. The video for the distribution of the powder distributes another layer of metal powder into the formed layer of cross section and sins the next layer. This is the layer by the layer. Until the whole part is in a way. The entire molding process is carried out in a technological chamber, vacuumed or filled with protective gas to prevent metal reaction with other gases at high temperatures.

In the technology of selective laser melting of metalsTaisinA laser with a high energy density and a small diameter of the spot is used, which can complete the manufacture of complex parts, the manufacture of which with conventional methods would require weeks or even months, for an extremely short cycle. Formed parts not only have accurate dimensional accuracy, high strength and high mass density, but also have excellent mechanical properties and other aspects. It is mainly used for the rapid manufacture of high -precision and high -quality metal parts.
Formed parts have the best surface quality without polishing.
Formed parts have high accuracy and are used for the manufacture of accurate prototypes.
The direct production of metal functional parts without intermediate processes, which greatly simplifies the production process.
It has a metallurgical structure, high density (> 99%), excellent mechanical properties and allows us to exclude the need for subsequent processing.
Details can be made in a matter of minutes or hours, depending on the size and complexity of the part.
Functional details of a complex geometric shape (for example, latches, living loops) can be made directly.
The material has a wide range of application, and its metal powder can be various single -component materials or multicomponent materials.
Especially suitable for individual production of functional parts by single or small batches.
