JEOL Brings Electron Beam Melting and a Taste of Japan

New exhibitor JEOL USA is showcasing the JAM-5200EBM electron beam melting 3D printer, its first foray into additive manufacturing. But the organization, headquartered in Japan, has a 70+ year history in electron beam technology as a supplier of electron microscopy and e-beam lithography, plus experience with additive manufacturing through products such as its scanning electron microscopes (SEMs), fine powder feeder, and a powder recovery system.

The JAM-5200EBM is the result of work with TRAFAM, an additive manufacturing consortium in Japan, through which JEOL applied its expertise to 3D printing technology. In electron beam melting (EBM), electrons are fired at a bed of metal powder to melt the material and form parts layer by layer; the JEOL machine uses the same energy source as a conventional microscope gun, which is said to be more consistent and precise than electron guns meant for welding. The EBM printer offers a long-life cathode, a helium-free environment and an “e-shield” to prevent powder dispersal. The platform is launching with Ti6Al4V, Ni718, and pure copper as its initial materials.
