SEPTEMBER 2018 Additive Manufacturing NEWS 8 Stephanie Hendrixson / Senior Editor Siemens reports that it successfully 3D-printed and engine tested a dry low emission (DLE) pre-mixer for the SGT-A05 aeroderivative gas turbine, with the results showing potential for significant reductions in CO emissions. In first engine testings of the 3D-printed DLE pre-mixer, there were no start issues; all fuel transitions were accomplished successfully without any controls modifications required; there were no combustion dynamics or noise; measurable CO emissions reductions were realized; and full power was achieved, the company says. The benefits of using additive manufacturing to produce this Siemens Successfully 3D Prints Combustion Component for SGT-A05 The gas turbine part showed potential for reduced CO emissions in engine testing. This 3D-printed dry low emission (DLE) pre-mixer for the SGT-A05 gas turbine was developed and tested by Siemens. Formnext 2018 to Take Place November 13-16 AM exhibition and conference Formnext encompasses more than 470 exhibitors showcasing 3D printing technologies and devel- opments, as well as conference sessions highlighting trends and issues in AM. Topics of discussion include industrial tooling, materials, mechanical engineering, metrology, prototyping, product processing and accessories.The event also offers an introductory seminar series titled Discover3DPrinting for attendees interested in adding 3D printing to their production processes. Additional highlights include the fourth-annual Formnext Start-up Challenge for businesses less than five years old and the Purmundus Challenge highlighting innovative ideas in design made possible through AM. Formnext 2018 will be held in hall 3 of Messe Frankfurt in Frankfurt, Germany, November 13-16. GE Additive Launches Manufacturing Partner Network GE Additive has launched its Manufacturing Partner Network (MPN) designed to create an open, competitive marketplace that will accelerate both supply and demand for AM. Manufacturing Partners (MPs) who are AM specialists will help customers make additive parts in volume, while benefiting from demand opportunities generated by GE Additive's sales teams and particular gas turbine component include time savings and a reduced number of parts in the component. From concept to engine test, the development took only seven months. The DLE pre-mixer is highly complex with over 20 parts involved in the casting and assembly using traditional manufacturing meth- ods. By utilizing Siemens-qualified nickel superalloys as the AM printing material, the 3D-printed component requires only two parts and lead time is reduced by approximately 70 percent. 3D printing of the DLE pre-mixer allows Siemens to simplify complexity in the production pro- cess, reduce external dependencies in the supply chain, and improve the geometry of the component, thus allowing a better fuel-air mix.
