Abstract
The combination of Additive Manufacturing (AM) and Hot Isostatic Pressing (HIP) offers great potential for industrial applications. Skillfully connecting AM and HIP creates a manufacturing process that unites the advantages of both processes. We demonstrate a production route for composite components by AM + HIP. A capsule made of wear-resistant or corrosion-resistant steel is additively manufactured by Laser-Powder Bed Fusion (LPBF). Before building, the geometry of the capsule is optimized by FEM simulation to obtain a desired shape. In a second step, the capsule is filled with structural steel powder and sealed in a conventional powder HIP process. The capsule remains on the component as an outer layer. In this way a complex-shaped, functional net shape composite component is produced. The composite components created by this route are characterized by metallographic investigations.
