The wavelength of red ray green laser pointer

The wavelength of red ray green laser pointer is approximately 600nm or more.
The results show that: slice part way, the laser cladding layer thickness, the laser output power, spot size, intensity distribution, scanning speed, scan spacing, scan mode, powder feeding device, the powder feed rate and the size of the powder particles and other factors forming the accuracy and strength of the parts affected. Is the difference with other rapid prototyping technology, laser cladding forming can be made into a very dense metal parts, and its strength to meet or exceed conventional casting or forging method of production of parts, and thus has a good prospect. Laser near shape (LENS) technology laser-shaped near the LENS technology is a combination of SLS and LCF, and maintain the advantages of both technologies. For the time being, semiconductor laser technology of this wave band for green ray green laser pointer is not that mature.
The selection of the metal powder in three forms: 1) a single metal; 2) metal and the low melting point metal binder; 3) metal and organic binder. As a result of a powder spreading, so no matter what form of powder, the lower the density of the laser sintering of metal, porous, low strength. To improve the sintering part strength, the need for post-processing, such as infiltration of resin, the low melting point metal, or hot isostatic pressing. But these post-processing will change the accuracy of the metal parts. Laser wafer stack Manufacturing (LOM) technology laser wafer stack manufacturing LOM technology is used to produce molds a new rapid prototyping technology. The principle is cutting sheet metal with a high-power laser beam, multi-layer thin slices and then superimposed, and its shape gradually changes, eventually to obtain the necessary prototype three-dimensional geometry. On the whole, the biggest distinguishes between these two types of green ray green laser pointer lie in their technology.
LOM technology to produce die, the cost is about 1/2, than the traditional method of saving and greatly shorten the production cycle. Used to produce the composite modulus of thin mold, the Progressive mold and other economic benefits are very significant. The technology has been widely used in foreign countries 2.6 Laser-induced thermal stress forming (LF), laser-induced thermal stress forming LF principle is based on thermal expansion and contraction of metal properties, the uneven heating of the material, resulting in pre-plastic deformation.
