6 September 13-14, 2016 | @learnadditive | Connecting Additive Manufacturing + Production 11:00 – 11:30 Automated Design of Functional Support Structures for Direct Metal Laser Sintering Joel Neidig | ITAMCO ITAMCO, along with University of Pittsburgh, Johnson & Johnson, and the University of Notre Dame have been in development of parametric designs of functional support structures for metal alloy feedstocks. Specifically, the project team aims to codify the design rules for support structures used in Direct Metal Laser Sintering (DMLS) to inform and then automatically recommend the optimal part orientation and the designs for optimized supports. Currently during part builds, support structures are not only essential to laying part foundations and providing structural support, but also are critical to eliminating part warp during powder recoating and improving heat extraction. However, few rules exist for designing support structures. Moreover, while AM machine tool software packages have the ability to add support structures, these existing capabilities are fairly primitive, not taking into consideration part orientation, distortion, or heat extraction uniformity. ITAMCO has written an Autodesk plugin called Atlas that assists designers in this environment. The benefits are two-fold, imparting expert knowledge to novice designers and automatic cost benefit analysis to the build process. 11:30 – 12:00 Challenges and Best Practices in Implementing a Production Unit for Industrial Additive Manufacturing Güngör Kara | EOS Products created by additive manufacturing have the ability to revolutionize entire industries and trigger shifts in a market's equilibrium. Companies that wish to take advantage of this innovative production method often have a problem finding the right application with which to make a start. The Consulting group of EOS, a leader in high-end AM solutions, has defined the lessons learned from various projects with internal OEMs and defined the "way to success" to benefit fully from the technology's potential. Industrial 3D printing offers a new dimension of design freedom to product developers and engineers. The combination of these new rules of engineering, such as functional part integration, geometries of unimaginably complex parts together with endless individualization offer totally new options to reshape the manufacturing and supply chain setup. The EOS Consulting group has identified key drivers and success factors during intensive customer projects around the globe. There is a similar pattern across industries when it comes to successful implementations of industrial AM production units, and this pattern will be shared during this presentation. 1:30 – 2:00 Which DLA Legacy Parts Are Additive Manufacturing Candidates? Thomas K Parks | LMI When is additive manufacturing a viable (and smart) option for legacy parts that were not designed for AM? Under an ongoing R&D; project (expected to be completed in mid- 2016), the Defense Logistics Agency (DLA) is developing a method to screen existing legacy parts for compatibility with AM. This project was undertaken in response to requests by Military Service activities for lists of DLA parts that they could manufacture as part of their own AM projects. Since DLA manages over 4.5 million unique weapon system parts on behalf of the Military Services, answering the request "please identify some DLA parts as AM candidates" was not a simple or quick evolution. This R&D; project built a screening process based on the following questions to address the
