Laser Metal Deposition System for Additive Manufacturing Material Property Development and Performance Predictions
Abstract
Additive Manufacturing (AM) has the promise and potential to dramatically affect how wedesign, manufacture, maintain, and repair the parts critical to our systems and platforms.Metallic AM today utilizes titanium, high nickel steels, and aluminum to produce through laseror electron beam by either selectively melting in a power bed or by directly depositing in a freeform method by building parts in a layer process. Parts from these AM processes can be utilizedin numerous applications from electronics, structural, propulsion, medical and all means oftransportation. As sophisticated as the new equipment is, there is relatively little informationavailable to the designer that allows them to design and predict finished part performance. Newresearch and education needs to be initiated that aligns with the new technology so a newgeneration of engineers and designers can exploit the technology in a safe and reliable(predictable) manner. Next generation design tools must build in the design requirements forstrength, durability, deformation, etc., so the part as it is integrated into the overall system is anefficient and optimized solution. Strategic initiatives require a dramatic shift in our ability toquickly design and deploy new hardware and systems in a rapidly changing world.State-of-the art AM equipment is proposed that will support a wide range of materials, materialresearch and the development of design concepts and design tools. This proposal is to purchase aRPMI-222~ Powder Fed Laser Metal Deposition System. This equipment will integrate into afamily of additive technology already available at NIAR providing a unique combination ofmaterials research, analytical modeling, and design optimization. This purchase will accelerateneeded research and open up opportunities for industry and academia.
