Chinaâ€™s 3D Laser Direct Manufacturing technology beyond the U.S. and Japan Recently emergent 3D printing technology is hot in world wide.In fact, 3D printing is one of 3D rapid shaping technologies, which can be broadly divided into seven categories, including 3D printing, laminated object manufacturing, selective laser sintering, selective laser melting, Electron beam melting, powder bed and inkjet head 3d printing and so on. The AVIC LASER is a subsidiary of AVIC Heavy Machinery as AVIC LASERâ€™s 30% stake held by the AVIC Heavy Machinery. The AVIC laser production technology team was established as early as 2000 when it has been put into R&D in â€œ3D Laser Direct Manufacturing technologyâ€. At first its study just followed the United States. In 2005, the United States Company Aeromet, which engaged in the titanium alloy laser molding manufacturing, never been able to produce large-size complex titanium alloy components for the performance to meet the requirements on main load-bearing parts, then has to closed down. However the AVIC LASER team does not give up. Especially by the continued support of the Chinese military funds, and after several years of R&D, it finally independently breaks through several world class technical problems, such as â€œinert gas protection systemâ€, â€œthermal stress discreteâ€, â€œdefect controlâ€, â€œmetal lattice growth controlâ€ and produces a 4-meter size and complex structure product whose performance meets the main load-bearing structure requirements and has showed its great commercial value. In Japan mechanical show, Japanese KOIWAI displays its power generation equipment radiators which produced by the technology imported from Sweden â€œAcramâ€â€˜s â€œEBMâ€ (Electron Beam Melting). Seen from the product picture, the radiator size in less than 1 meter. Besides, the generation radiator is not main load-bearing component and its structural strength and fatigue life performance is greatly backward from the AVIC LASERâ€™s. Japan still has big technology gap in this area. AVIC LASERâ€™s 3D molding technology, which estimated by the Ministry of Financeâ€™s State-owned intellectual property valuation, worth more than 100 million yuan. The project is also expected to be the national technology invention award which represents the highest honor in the field of national technical achievements. After 10 years of theory and technology accumulation, AVIC LASER overcome the difficulty of large structural parts 3D Direct Manufacturing technology on high temperature metal, including titanium alloy, high-strength steel, high temperature & high strength steel. Compared with conventional processes, it saves 90% of the very expensive raw materials, and creates a myth of ultra-high 90% gross margin in manufacturing. Assuming processing 1 ton weight titanium alloy complex structural parts, a traditional process cost is about 25 million yuan, and Laser Direct Manufacturing costs only 1.3 million, only 5% of the traditional process.
