Selective laser sintering

  • 27-Dec-2010 01:24 EST

The EOSINT M280 machine from EOS is an additive manufacturing system for metal components. The machine maximizes part quality and reproducibility while improving cost-effectiveness and user-friendliness. Its technological advancements compared to the previous version include a 400-W fiber laser option to melt more metal powder per second for shorter build times and higher system productivity. An increase in the maximum build height to 325 mm, compared with 215 mm for the M 270, allows production of taller parts. This is useful for hybrid part building, a concept used for prototype tooling, in which complex parts are produced by building additional material on top of a prefabricated part. Optimized gas management includes a high-velocity laminar flow of protective gas across the build area combined with a high-capacity recirculating filter system for more uniform process conditions and stable melting behavior, even over long periods and with higher laser power. The system incorporates the Part Property Management concept and supports 10 series of materials, including EOS NickelAlloy IN625.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.
Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
