Product News Laser Sintering System Builds Metal Parts EOS's M 290 direct metal laser sintering (DMLS) system, the successor to its EOSINT M 280, is designed for the production of serial components, spare parts and prototypes. In addition to a build volume of 250 × 250 × 325 mm (9.8" × 9.8" × 12.8"), the M 290 offers monitoring functions for both the system itself and for the build process. Separately, EOS has collaborated with Airbus Group Innovations (previously EADS Innovation Works) to eval- uate the environmental impact of rapid investment casting versus DMLS using an Airbus A320 nacelle hinge bracket. The study found reduced carbon dioxide emissions over the lifecycle of the DMLS-produced part, in addition to weight reduction. The testing will serve as the basis for continued "cradle-to-cradle" study into other aerospace parts, pro- cesses and end-of-life strategies, EOS says. eos.info 14— AM Supplement Hybrid Machine Combines Additive, Subtractive Processes DMG MORI's Lasertec 65 hybrid manufacturing machine combines additive and subtractive processes to produce a complete part from powder. Rather than powder bed technology, the machine uses a powder spray technique that deposits material at 10× to 40× rates. It then uses conven- tional milling/turning processes to remove material from unwanted areas. us.dmgmori.com Trumpf Forms Joint Venture for 3D Printing German machine tool maker Trumpf has formed a joint venture with Italian laser manufacturer Sisma to develop a 3D printer capable of mass production of metal components. Both companies are bringing expertise, human resources and capital to the venture. us.trumpf.com / sisma.com LPW Technology Adds U.S. Subsidiary The U.K.'s LPW Technology has established a subsidiary based in Pittsburgh, Pennsylvania, to provide support and sales to U.S. customers of its metal powders for addi- tive manufacturing. The new offce will develop powders specifcally for selective laser melting, laser metal deposition and electron beam melting, including standard powders and custom alloys. lpwtechnology.com GKN Aerospace to Lead AM R&D; Group GKN Aerospace will lead a consortium of U.K. companies in "Horizon (AM)," a research and development program aimed at building on the company's additive manufacturing capability to produce lighter, complex components cost effectively. The company expects the new processes to unlock innovations in low-drag, high-performance wing designs, and lighter, more effcient engine systems, leading to reductions in aircraft fuel consumption and emissions. The Horizon (AM) team includes GKN, Renishaw, Delcam, and the Universities of Sheffeld and Warwick. It is backed by the U.K.'s Aerospace Technology Institute. gknaerospace.com Electron Beam AM System Comes to Market Sciaky Inc. will be offering its electron beam additive manu- facturing (EBAM) systems for purchase. The company has predominantly offered the process as a service-only option to help manufacturers produce large-scale prototypes and production parts from metals such as titanium, tantalum, stainless steel and Inconel. The process starts with a 3D model from a CAD pro- gram, then a fully-articulated, moving electron beam welding gun deposits metal (via wire), layer by layer, until the part reaches near-net shape and is ready for minor post-produc- tion machining. Deposition rates range from 7 to 20 lbs/hr., depending on part geometry and material. sciaky.com System Incorporates Sintering, Milling The Lumex Avance-25 from MC Machinery Systems and Matsuura Machinery Corp. combines metal laser sintering technology with high-speed milling technology to produce complex parts using digital engineering and 3D data. Metal powders are melted and sintered via laser, while surfaces are precisely milled at high speeds. mcmachinery.com / lumex-matsuura.
