1. ADDITIVE MANUFACTURING PROJECT CLUSTER MEETING AM for Metal Parts Fundació CIM C/Llorens i Artigas, 12 Parc Tecnològic de Barcelona Barcelona, Spain 2 May 2016 Jeff Grabowski Manager of Applications and Product Commercialization QuesTek Innovations (Chicago, USA)

2. Design of new alloys specifically tailored for AM Use of traditional wrought/cast alloys to AM processing has limitations (e.g., forging alloys not meant for casting) New alloys designed specifically for AM need to consider: Rapid solidification Intense residual stresses Non-equilibrium microstructures QuesTek has demonstrated ability to modify alloys across Al, Ni, Ti and W to improve properties and processibility vs “off the shelf” alloys

3. Exploitable results (ERs) Scale up and commercialize QuesTek’s Al alloy for AM, combining processing of AlSi12/AlSi10Mg but with performance of 6061/7050 Further development and commercialization of QuesTek-designed Ti-6-4 Mod, which has demonstrated capability to outperform traditional Ti-6-4 Design of entirely new alloys tailored for AM, based on Ni, Ti, Co, Fe, or other elements, achieving a set of performance requirements defined by an end-user QuesTek has already shown success in designing new alloys that are aerospace approved (AMS and MMPDS) and are being used in demanding aerospace and other applications.
