Only a few companies in the world,titanium round bar, such as Sciaky in the United States and Xi'an Zhirong in China, can provide commercial products. Expand the full text The technical principle is as follows: in a vacuum environment, an electron beam with high energy density bombards a metal surface to form a molten pool, a metal wire is fed into the molten pool through a wire feeding device and is molten, the molten pool moves according to a pre-planned path, and the metal material is solidified and accumulated layer by layer to form compact metallurgical bonding until a metal part or blank is manufactured. Schematic diagram of electron beam fuse additive manufacturing technology Shaanxi Satellite TV's Report on Xi'an Intelligent Fuse Electron Beam Metal 3D Printing System in 2017 The characteristics of this technology are very obvious,ti6al4v eli, such as printing in vacuum environment, effectively avoiding the mixing of impurity elements, fast forming speed, high material utilization rate, stainless steel fuse efficiency up to 15 kg/H, suitable for rapid manufacturing of large structural parts, good consistency of forming process, and so on; It can be used for additive manufacturing of functional gradient materials (FGM) and metal matrix composites, as well as processing of refractory metals such as tungsten, molybdenum, 3d titanium wire ,3d titanium wire, niobium and tantalum. However, the surface accuracy of the parts is not high, and CNC processing is needed in the later stage. Its self-developed fuse-based electron beam metal additive manufacturing system is suitable for high-speed and low-cost manufacturing of large metal structural parts. In the field of fuse electron beam metal printing technology and powder bed electron beam metal printing technology,nickel titanium wire, it has the core technology of independent intellectual property rights. It designs and produces the Zcomplex ® series of fusible electron beam metal printing systems based on its leading EBVF3 ® technology platform and the ZScan ® series of powder bed electron beam metal printing systems based on its exclusive SmartBeam ® technology platform. In order to expand the application of aviation titanium alloy structural parts with high material performance requirements, especially those bearing fatigue loads, Xi'an Zhiyu Technology Team has carried out a large number of research on titanium alloy electron beam fuse additive manufacturing technology since 2017 and made a breakthrough by the end of 2020.
