Abstract Scope |
Powder metallurgy hot isostatic pressing (PM-HIP) through additive manufacturing (AM) is an innovative process that combines traditional and advanced manufacturing advantages. It enables the creation of large parts, several feet in size, with complex geometries that are nearly impossible or take very long to produce, up to several months, using current AM techniques. The PM-HIP process increases part density under high temperature and pressure, making it sensitive to external forces during sintering. However, using AM, specifically wire-arc direct energy deposition (wire-arc DED), to print the shell structure for PM-HIP can lead to part distortion. Understanding AM-induced distortion behavior is essential for optimizing the PM-HIP process. In this research, we model a complex, large part using the finite element method and validate distortion with laser scanning data. We will examine the effect of AM-induced distortion on PM-HIP and propose optimal conditions to minimize its impact. |
