a combination of physical metallurgy

Meanwhile, the Soviet Union also proposed the theory of laser Basov and general Huoluo Fu. The three shared the 1964 Nobel Prize in Physics. Currently, laser technology has been integrated into our daily lives the. In the coming years, the laser will give us more of a miracle. This kind of  laser pointer  sells really good in American market.
Selective laser melting (SelectiveLaserMelting, referred to as SLM) technology is in selective laser sintering (SLS) technology developed on the basis of. SLM features are: (1) the use of high power density, small spot of laser beam machining of metal, making the metal parts with a size of 0.1 mm accuracy; (2) melting of metal parts produced with a combination of physical metallurgy, the relative density of almost 100%, greatly improving the performance of metal parts; (3) The laser spot diameter is small, so a lower melting point metal melting power, making the use of single-component metal powder to produce parts as possible. Figure 2 shows the German EOSGmbH companies use selective laser melting (SLM) process manufacturing metal parts. Laser multi-layer (or D / D) Cladding direct rapid prototyping technology is based on rapid prototyping technology with simultaneous feeding laser cladding technology developed a high-tech manufacturing techniques, and its essence is a computer-controlled three-dimensional laser cladding. Because of the rapid solidification characteristics of laser cladding, the manufacture of metal parts with a uniform dense dendrites and excellent quality, density and performance of its metal parts with quite conventional. The customer wants to know the shipping details of laser pointer before ordering laser pointer .
Laser multi-layer cladding developed a variety of methods, including the most representative of the U.S. Sandia National Laboratories (SandiaNationalLaboratories) developed called laser engineered net shaping technology (LaserEngineeredNetShaping, called LENS) Rapid Prototyping of metal parts. This method has been successfully manufactured using stainless steel, maraging steel, nickel-based superalloys, tool steels, titanium alloys, magnetic materials and nickel-aluminum intermetallic compound parts, parts density reached almost 100%.
