| Abstract Scope |
In this talk, I will primarily focus on applicability of multiscale directed energy deposition (DED) processes for real world applications. Two major efforts will be discussed in particular utilizing large scale wire arc additive manufacturing (WAAM) for automotive tooling and laser powder blown DED for hardfacing coating applications. Large Scale Additive Manufacturing (LSAM) is a rapidly growing research domain which allows printing heavy metallic objects and large-size parts more quickly and efficiently. However, there are several challenges while fabricating large scale components using metal AM process such as proper deposition process development, heat management and consistent mechanical properties of printed parts. In this talk, fabrication of large-scale steel components using closes loop deposition system-based wire arc additive manufacturing (WAAM) will be discussed. The specific manufacturing process was used to fabricate thin walled builds using ER410 welding wire. Necessity of microstructural analyses to reduce the scatter in mechanical properties of ‘as-printed’ large-scale components will be identified to resolve anisotropy and scatter in mechanical properties. |
